Carlton mourns the loss of one of the greats of the game

<p>The Australian football world is in mourning following the passing of one of the game's most electrifying figures, Peter Bosustow, aged 67.</p> <p>Bosustow, affectionately known as "The Buzz", died early Monday morning in Perth after a long battle with cancer. He was surrounded by his wife Shelley, son Brent and daughter Brooke, who were by his side to say their final goodbyes.</p> <p>The son of former Carlton player Bob Bosustow, Peter lit up Princes Park from the moment he crossed from Perth in 1981, joining fellow Western Australian Ken Hunter. Both became instant sensations, but it was Bosustow's acrobatics, sharp goal sense and larger-than-life personality that quickly made him a Carlton cult hero.</p> <p>In just three seasons and 65 games for the Blues, Bosustow made an indelible impact, booting 146 goals and helping lead the club to back-to-back premierships in 1981 and 1982. His inaugural season remains one of the most memorable in AFL history, winning both the Goal of the Year and Mark of the Year awards, alongside lifting the premiership trophy.</p> <p>Former teammate Ken Hunter remembered Bosustow fondly, saying, “I think of what a character ‘Buzz’ was and how much he took to the big stage. He was a unique character and a rare football talent in equal measure. The Carlton people loved ‘Buzz’ and he loved Carlton.”</p> <p>Bosustow's highlight reel moments – none greater than his soaring mark over Geelong's John Mossop at Princes Park and his instinctive goal against Ian Nankervis at VFL Park – are still cherished by Blues fans. His ability to turn a game in a few magical moments made him a constant crowd favourite.</p> <p>Former Carlton coach David Parkin paid a heartfelt tribute, describing Bosustow as “an exceptional talent” who was "probably as exciting a player to watch as we ever had". Parkin recalled Bosustow's breathtaking smother, gather and goal during the 1981 semi-final as the quintessential example of his rare brilliance.</p> <p>After three seasons, Bosustow returned to WA in 1984 due to his father's illness. He continued to shine at WAFL level with Perth, where he played 141 games and kicked 379 goals, also representing WA against Victoria and South Australia. He topped Perth’s goalkicking three times and was later named in the club's Team of the Century.</p> <p>A comeback attempt at Carlton in 1986 ultimately fell short, but his connection with the club and its supporters never wavered.</p> <p>Bosustow's final years were marked by courage in the face of illness. Diagnosed with bowel and liver cancer, he fought valiantly and even celebrated a brief cancer-free period in 2023. However, his second battle with cancer recently became public, and earlier this month he was hospitalised in Perth.</p> <p>Remarkably, Bosustow spent his final evening watching his beloved Blues claim a stirring victory over Geelong at the MCG – the same club against which he once performed some of his most iconic feats. According to reports, he raised a fist in celebration at the final siren.</p> <p>Throughout his illness, Bosustow received widespread support from the football community, with fundraising efforts in 2022 attended by many of his former teammates and friends.</p> <p>Peter Bosustow leaves behind a legacy as one of football’s most charismatic and spectacular talents. His high-flying marks, impossible goals and infectious spirit will forever be part of Carlton's rich history — and in the hearts of all who were lucky enough to witness "The Buzz" in full flight.</p> <p><em>Images: Carlton FC</em></p>

Australia has the highest gambling losses in the world. Is it time for mandatory limits?

<div class="theconversation-article-body">Gambling prevalence studies provide a snapshot of gambling behaviour, problems and harm in our communities. They are typically conducted about every five years.</p> <p>In some Australian states and territories, four or five have been conducted over the past 20 or so years. These have provided a snapshot into how gambling has changed – and how it has not.</p> <p>So, how has gambling in Australia changed in the past two decades or so, and where may we be heading?</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">Australia has the highest gambling losses in the world.<br />Australia should: <br />🚫 Ban gambling ads<br />🎰 Introduce loss limits on pokies and online gambling<br />📉 Progressively cut the number of pokies in each state</p> <p>Our new report shows how governments should prevent gambling harm.… <a href="https://t.co/7U3IgzOLSp">pic.twitter.com/7U3IgzOLSp</a></p> <p>— Grattan Institute (@GrattanInst) <a href="https://twitter.com/GrattanInst/status/1831297414080176469?ref_src=twsrc%5Etfw">September 4, 2024</a></p></blockquote> <h2>The intensification of gambling</h2> <p>In 1997-98, the Productivity Commission found <a href="https://www.pc.gov.au/inquiries/completed/gambling/report/summary.pdf">about 82% of Australians</a> had gambled in the previous 12 months.</p> <p>Almost all further prevalence studies show the proportion of adults gambling has declined substantially over time.</p> <p>The <a href="https://www.gambleaware.nsw.gov.au/resources-and-education/check-out-our-research/published-research/nsw-gambling-survey-2024">2024 NSW prevalence survey</a>, for example, found 54% reported gambling in the previous 12 months, down from 69% in 2006.</p> <p>While fewer people are gambling, the proportion of people experiencing problems has not changed much, <a href="https://www.qgso.qld.gov.au/statistics/theme/society/gambling/australian-gambling-statistics">nor has gambling turnover</a>.</p> <p>In some states, gambling turnover has increased, even when you take inflation into account.</p> <p>So while a smaller proportion of people are gambling, those who do gamble are doing so more frequently, and spend more money – a phenomenon we have described as the “intensification” of the industry.</p> <p>As figures from the Grattan Institute show, the vast majority of gambling spend comes from a very small proportion of people who gamble.</p> <p><iframe id="Z6EYJ" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/Z6EYJ/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe></p> <h2>What’s the problem?</h2> <p>Typically, the focus in gambling studies has been on “problem gamblers”, a term we now avoid because it can be stigmatising.</p> <p>This refers to those experiencing severe problems due to their gambling, which is typically <a href="https://www.justice.vic.gov.au/justice-system/safer-communities/gambling/victorian-population-gambling-and-health-study-2023">about 1% of the adult population</a>, and around 2% of people who gamble.</p> <p>This doesn’t sound like much, until you remember 1% of adults in Australia is more than 200,000 people. That’s a lot of people struggling with severe problems.</p> <p>Based on recent prevalence surveys in Australia, these gamblers spend <a href="https://www.gambleaware.nsw.gov.au/resources-and-education/check-out-our-research/published-research/nsw-gambling-survey-2024">about 60 times as much</a> as people who do not experience problems.</p> <p>However, that’s just the most severe cases.</p> <h2>How gambling harms people</h2> <p>When most people think of gambling harm, they think about financial harm. But gambling can cause problems with relationships, work and study, emotional and psychological harm, and <a href="https://bmcpublichealth.biomedcentral.com/articles/10.1186/s12889-016-2747-0">even cause health issues</a>.</p> <p>Some degree of gambling harm is experienced by <a href="https://www.gambleaware.nsw.gov.au/resources-and-education/check-out-our-research/published-research/nsw-gambling-survey-2024">around 10-15%</a> of people who gamble.</p> <p>Some groups are overrepresented: young men typically experience very high levels of harm compared to others. Other overrepresented groups are:</p> <ul> <li>those who have not completed tertiary education</li> <li>people who speak a language other than English</li> <li>people who identify as Aboriginal or Torres Strait Islander.</li> </ul> <p>Harm isn’t just experienced by people who gamble, though – it impacts the people around them.</p> <p>While young men are more likely to experience harm from their own gambling, <a href="https://www.gambleaware.nsw.gov.au/resources-and-education/check-out-our-research/published-research/nsw-gambling-survey-2024">women, particularly young women</a>, are most likely to experience harm from someone else’s gambling.</p> <p>When we take all of these sources of harm into account, we get a much better picture of gambling harm in our community: <a href="https://www.gambleaware.nsw.gov.au/resources-and-education/check-out-our-research/published-research/nsw-gambling-survey-2024">around 15-20% of all adults</a> (not all gamblers) experience harm.</p> <p>That’s very different to the figure of 1% we’ve focused on in the past.</p> <p>We’re still missing some accounting, though: we don’t know how much harm is experienced by people under 18, for example, because prevalence studies typically only include adults.</p> <h2>Where does the harm come from?</h2> <p>The most problematic form in Australia is pokies, responsible for <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10260219/#:%7E:text=EGMs%20are%20responsible%20for%2051,problems%20due%20to%20low%20participation.">about 51-57% of problems</a>.</p> <p>Casinos are responsible for <a href="https://ftp.justice.vic.gov.au/justice-system/safer-communities/gambling/victorian-population-gambling-and-health-study-2023">another 10-14%</a>, although fewer people have been gambling in casino games in recent years.</p> <p>Sports betting and race betting together account for about another 19-20% of harm.</p> <p>Between them, pokies, casino games and sports and race betting account for about 90% of harm to Australian gamblers.</p> <p><iframe id="w2wEY" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/w2wEY/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe></p> <h2>Availability is an issue</h2> <p>This widespread availability of pokies is the biggest single driver behind gambling harm in Australia.</p> <p><iframe id="hIgeD" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/hIgeD/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe></p> <p>In other countries, pokies are limited to venues that are specifically used for gambling, like casinos or betting shops.</p> <p>We have pokies in a huge number of our pubs and clubs, except in Western Australia.</p> <p>A couple of years ago, we used national prevalence data to compare gambling problems in WA <a href="https://akjournals.com/view/journals/2006/12/3/article-p721.xml">to the rest of the country</a>.</p> <p>A higher percentage of adults in WA gamble, but mostly on the lotteries which are typically <a href="https://theconversation.com/pokies-lotto-sports-betting-which-forms-of-problem-gambling-affect-australians-the-most-240665">not associated with much harm</a>.</p> <p>Gambling on pokies is far less prevalent in WA because they’re only available in one casino. Gambling problems and harm are about one-third lower in WA, and our analysis shows this can be attributed to the limited access to pokies.</p> <p>This also tells us something important. If pokies are not available, people will typically not substitute them with other harmful forms. It points to the role of the availability of dangerous gambling products in gambling harm, rather than personal characteristics.</p> <p>Online gambling has also become a lot more available. Most of us now have a mobile phone almost surgically implanted onto our hand, making online gambling more accessible than ever. Not surprisingly, <a href="https://www.gamblingresearch.org.au/publications/second-national-study-interactive-gambling-australia-2019-20">online gambling continues to increase</a>.</p> <h2>An obvious solution to try</h2> <p>Governments have taken increasingly proactive measures to help address gambling harm, such as the <a href="https://www.dss.gov.au/gambling/resource/national-consumer-protection-framework-online-wagering-national-policy-statement">National Consumer Protection Framework for Online Gambling</a>, strategies for minimising harm such as NSW’s investment into <a href="https://www.nsw.gov.au/media-releases/gambleaware-week-0">gambling harm minimisation</a>, Victoria’s <a href="https://www.theguardian.com/australia-news/2024/nov/26/victoria-pokies-changes-limits-new-laws">proposed reforms on pokies</a> including mandatory precommitment limits, Queensland’s <a href="https://www.publications.qld.gov.au/dataset/gambling-harm-min/resource/84d444db-97e0-4be0-8e87-0c6f0cb412d6">Gambling Harm Minimisation Plan</a> and the ACT’s <a href="https://www.gamblingandracing.act.gov.au/__data/assets/pdf_file/0009/1436580/Strategy-for-gambling-harm-prevention.pdf">Strategy for Gambling Harm Prevention</a>.</p> <p>Voluntary limits have been trialled to help people keep their gambling under control, but have had <a href="https://www.abc.net.au/news/2024-12-03/nsw-government-cashless-gaming-trial-findings-released/104679384">virtually no uptake</a>.</p> <p>For example, the recent <a href="https://www.liquorandgaming.nsw.gov.au/__data/assets/pdf_file/0018/1340136/evaluation-of-the-nsw-digital-gaming-wallet-trial-2024.pdf">NSW Digital Gaming Wallet trial</a> was conducted in 14 venues. Only 32 people were active users, and 14 of these were deemed genuine users. <a href="https://www.adelaide.edu.au/saces/ua/media/652/evaluation-of-yourplay-final-report_0.pdf">Another study</a> found only 0.01% of all money put through machines in Victoria used the voluntary YourPlay scheme.</p> <p>The problem with voluntary limits is, no one volunteers.</p> <p>Mandatory limits though are almost certainly necessary, just like we have mandatory limits for how fast you can drive, or how much you can drink before the bartender puts you in a taxi.</p> <p>There will almost certainly be push back against this, just like the introduction of mandatory seatbelts in the 1970s, or <a href="https://www.abc.net.au/news/2023-10-04/road-safety-history-australia-toll-increase/102903364">the introduction of random breath testing</a>.</p> <p>Now, we accept them as important public health measures.</p> <p>History tells us the same will happen with mandatory gambling limits, even if we’re a bit uncomfortable about it at first.<!-- Below is The Conversation's page counter tag.

Dave Hughes reveals I’m A Celeb weight loss

<p>Dave Hughes spent 25 days in the jungle for this year's season of<em> I'm A Celebrity...Get Me Out of Here! </em>and despite being eliminated, his three-and-a-half weeks of camp life had a staggering effect on his body.</p> <p>“I lost eight kilos and I’m stronger now than when I went in there,” he told <em>news.com.au</em>.</p> <p>He explained that when he first joined the show he struggled to do laborious tasks like carrying a crate of firewood back to camp without assistance.</p> <p>“I’d be holding one side of the crate while my fingers almost snapped off, with another burly bloke like (former NRL player) Sam Thaiday on the other side,” he said.</p> <p>“But by the end of the month, I’m carrying the whole crate on my own. My fingers are loving the task. I’m just living my best life.”</p> <p>He also made progress in the "jungle gym" a workout station contestants could use to keep fit. </p> <p>“There was a bench press there and on the first day, the heaviest weights, I could do 20 (reps). On the day I got kicked out, I did 52," he said. </p> <p>“Sam (Thaiday) says I now look like a pregnant greyhound … I think that’s a compliment, so I’m happy," he said. </p> <p><em>Image: I'm A Celeb/ news.com.au</em></p>

Why do some people’s hair and nails grow quicker than mine?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/michelle-moscova-310728">Michelle Moscova</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>Throughout recorded history, our hair and nails played an important role in signifying who <a href="https://www.psychiatrictimes.com/view/gender-culture-and-social-constructs-in-body-focused-repetitive-behaviors">we are and our social status</a>. You could say, they separate the caveman from businessman.</p> <p>It was no surprise then that many of us found a new level of appreciation for our hairdressers and nail artists during the COVID lockdowns. Even Taylor Swift reported <a href="https://abcnews.go.com/GMA/Culture/taylor-swift-reveals-shes-cutting-hair-covid-19/story?id=74757540&amp;t">she cut her own hair during lockdown</a>.</p> <p>So, what would happen if all this hair and nail grooming got too much for us and we decided to give it all up. Would our hair and nails just keep on growing?</p> <p>The answer is yes. The hair on our head grows, on average, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9917549/">1 centimeter per month</a>, while our fingernails grow an average of just <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11436330/">over 3 millimetres</a>.</p> <p>When left unchecked, our hair and nails can grow to impressive lengths. Aliia Nasyrova, known as the Ukrainian Rapunzel, holds the world record for the longest locks on a living woman, which measure an <a href="https://www.youtube.com/watch?v=1TdlEIQdVwo&amp;t=81s">impressive 257.33 cm</a>.</p> <p>When it comes to record-breaking fingernails, Diana Armstrong from the United States holds that record <a href="https://www.youtube.com/watch?v=nwql937j-7Q">at 1,306.58 cm</a>.</p> <p>Most of us, however, get regular haircuts and trim our nails – some with greater frequency than others. So why do some people’s hair and nails grow more quickly?</p> <h2>Remind me, what are they made out of?</h2> <p>Hair and nails are made mostly from keratin. Both grow from matrix cells below the skin and grow through different patterns of cell division.</p> <p>Nails grow steadily from the matrix cells, which sit under the skin at the base of the nail. These cells divide, pushing the older cells forward. As they grow, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5383514/">the new cells slide</a> along the nail bed – the flat area under the fingernail which looks pink because of its rich blood supply.</p> <p>A hair also starts growing from the matrix cells, eventually forming the visible part of the hair – the shaft. The hair shaft grows from a root that sits under the skin and is wrapped in a sac known as the hair follicle.</p> <p>This sac has a nerve supply (which is why it hurts to pull out a hair), oil-producing glands that lubricate the hair and a tiny muscle that <a href="https://www.ncbi.nlm.nih.gov/books/NBK546248/">makes your hair stand up</a> when it’s cold.</p> <p>At the follicle’s base is the hair bulb, which contains the all-important hair papilla that supplies blood to the follicle.</p> <p>Matrix cells near the papilla divide to produce new hair cells, which then harden and form the hair shaft. As the new hair cells are made, the hair is pushed up above the skin <a href="https://www.jidonline.org/article/S0022-202X(15)41553-2/fulltext">and the hair grows</a>.</p> <p>But the papilla also plays an integral part in regulating hair growth cycles, as it sends signals to the stem cells to move to the base of the follicle and form a hair matrix. Matrix cells then get signals to divide and start a new growth phase.</p> <h2>Unlike nails, our hair grows in cycles</h2> <p>Scientists have identified <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9917549/">four phases of hair growth</a>, the:</p> <ol> <li> <p>anagen or growth phase, which lasts between two and eight years</p> </li> <li> <p>catagen or transition phase, when growth slows down, lasting around two weeks</p> </li> <li> <p>telogen or resting phase, when there is no growth at all. This usually lasts two to three months</p> </li> <li> <p>exogen or shedding phase, when the hair falls out and is replaced by the new hair growing from the same follicle. This starts the process all over again.</p> </li> </ol> <figure class="align-center "><img src="https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=308&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=308&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=308&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=387&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=387&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=387&amp;fit=crop&amp;dpr=3 2262w" alt="Stages of hair growth graphic" /><figcaption><span class="caption">Hair follicles enter these phases at different times so we’re not left bald.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-vector/stages-hair-growth-cycle-vector-isolated-2433656865">Mosterpiece/Shutterstock</a></span></figcaption></figure> <p>Each follicle goes through this cycle <a href="https://www.longdom.org/open-access/a-note-on-the-human-hair-follicle-from-the-origin-to-the-death-93871.html?t">10–30 times in its lifespan</a>.</p> <p>If all of our hair follicles grew at the same rate and entered the same phases simultaneously, there would be times when we would all be bald. That doesn’t usually happen: at any given time, only one in ten hairs is in the resting phase.</p> <p>While we lose about <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9917549/">100–150 hairs daily</a>, the average person has <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9917549/">100,000 hairs</a> on their head, so we barely notice this natural shedding.</p> <h2>So what affects the speed of growth?</h2> <p>Genetics is the most significant factor. While hair growth rates vary between individuals, they tend to be <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4201279/">consistent among family members</a>.</p> <p>Nails are also influenced by genetics, as siblings, especially identical twins, tend to have <a href="https://link.springer.com/referenceworkentry/10.1007/978-3-319-26594-0_121-1">similar nail growth rates</a>.</p> <p>But there are also other influences.</p> <p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9917549/">Age makes a difference</a> to hair and <a href="https://link.springer.com/referenceworkentry/10.1007/978-3-319-26594-0_121-1">nail</a> growth, even in healthy people. Younger people generally have faster growth rates because of the slowing metabolism and cell division that comes with ageing.</p> <p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7432488/">Hormonal changes</a> can have an impact. Pregnancy often <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7432488/">accelerates</a> hair and nail growth rates, while menopause and high levels of the stress hormone cortisol can <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7432488/">slow growth rates</a>.</p> <p>Nutrition also changes <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6380979/">hair</a> and <a href="https://ijdvl.com/nails-in-nutritional-deficiencies/?t">nail</a> strength and growth rate. While hair and nails are made mostly of keratin, they also contain water, fats and various minerals. As hair and nails keep growing, these minerals need to be replaced.</p> <p>That’s why a balanced diet that includes sufficient nutrients to support your hair and nails is essential for maintaining their health.</p> <p>Nutrient deficiencies may contribute to hair loss and nail breakage by disrupting their growth cycle or weakening their structure. Iron and zinc deficiencies, for example, have both been linked to <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6380979/">hair loss</a> and <a href="https://ijdvl.com/nails-in-nutritional-deficiencies/?t">brittle nails</a>.</p> <p>This may explain why thick hair and strong, well-groomed nails have long been associated with perception of good health and high status.</p> <p>However, not all perceptions are true.</p> <h2>No, hair and nails don’t grow after death</h2> <p>A persistent myth that may relate to <a href="https://www.britannica.com/topic/vampire">the legends of vampires</a> is that hair and nails continue to grow after we die.</p> <p>In reality, they only <em>appear</em> to do so. As the body dehydrates after death, the skin shrinks, making hair and nails <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2151163/">seem longer</a>.</p> <p>Morticians are well aware of this phenomenon and some <a href="https://www.adomonline.com/mortuary-man-reveals-how-he-handles-nails-of-the-dead/?t">inject tissue filler</a> into the deceased’s fingertips to minimise this effect.</p> <p>So, it seems that living or dead, there is no escape from the never-ending task of caring for our hair and nails.<!-- Below is The Conversation's page counter tag.

Christmas can be challenging for people with hearing loss. Here are 7 ways you can help

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/katie-ekberg-1534998">Katie Ekberg</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> and <a href="https://theconversation.com/profiles/louise-hickson-2280688">Louise Hickson</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p>For many people, Christmas can be the most social time of the year. The holiday period is often filled with parties, lunches, dinners and celebrations of all kinds with family, friends and colleagues.</p> <p>For adults with hearing loss, however, these social gatherings can bring unique challenges. Communicating with others can be difficult, particularly in group conversations. And the more <a href="https://www.tandfonline.com/doi/full/10.1080/14992027.2019.1670363">background noise</a> there is (for example, Christmas music or children playing), the harder it is.</p> <p>For age-related or acquired hearing loss, hearing ability typically starts to decline from <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0107720">age 50 onwards</a>. <a href="https://www.health.gov.au/hearing-health/resources/publications/one-in-six-australians-experience-hearing-loss-poster-0?language=en">One in six Australians</a> experience some hearing loss, so it’s possible someone around your Christmas dinner table will be struggling to hear.</p> <p>Unfortunately, many adults with hearing loss suffer these challenges in silence. Our <a href="https://www.tandfonline.com/doi/full/10.1080/14992027.2023.2293651">research</a> shows adults with hearing loss often hide their hearing loss from others, even close family members and friends, because of feeling shame due to stigma.</p> <p>But there are some things you can do to ensure a loved one with hearing loss is included this Christmas.</p> <h2>Stigma and stereotypes</h2> <p>Stigma is when someone is treated differently by others due to a particular physical or social attribute.</p> <p>Across a <a href="https://www.tandfonline.com/doi/full/10.1080/14992027.2023.2293651">series of studies</a>, we conducted surveys and interviews with adults with hearing loss, their families and hearing care professionals to explore experiences of stigma for adults with hearing loss. Our research also included video recordings of real-life conversations between adults with hearing loss and their families and friends.</p> <p>The <a href="https://www.tandfonline.com/doi/full/10.1080/14992027.2024.2353862">results</a> suggested people often associate hearing loss with negative stereotypes of ageing, disability, reduced intelligence, having a problem or weakness, and difference. For example, one participant with hearing loss told us:</p> <blockquote> <p>Once they are aware that you can’t really comprehend or hear what they’re saying, they treat you different. And it’s not always positive, it’s quite often negative […] Even people who are familiar with you, my twin brother, he thinks that there’s something wrong with me because I can’t hear him properly.</p> </blockquote> <p>Old age was the most common stereotype associated with hearing loss. For example, one adult with hearing loss commented:</p> <blockquote> <p>I guess it’s just a sign of ageing. Like wearing glasses and grey hair.</p> </blockquote> <p>But as hearing can start declining from middle age, many adults experiencing hearing difficulties do not fit this stereotype.</p> <p>We see this stereotype appear in popular media as well. For example, in the TV show Bluey, the character Bingo dresses up as a “<a href="https://www.bluey.tv/characters/granny-rita/">Can’t-Hear-Anything granny</a>” in a number of episodes.</p> <p>In <a href="https://www.tandfonline.com/doi/full/10.1080/14992027.2024.2418970">our research</a>, people with hearing loss reported feeling embarrassment, shame, frustration, sadness and fatigue from trying to manage their hearing difficulties during everyday conversations.</p> <p>In the results of <a href="https://www.tandfonline.com/doi/full/10.1080/14992027.2023.2293651">a survey</a> currently under peer review, almost two-thirds felt other people laughed about or treated their hearing loss as a joke, often making them feel uncomfortable.</p> <p>An example <a href="https://www.tandfonline.com/doi/full/10.1080/14992027.2024.2389189">of this teasing</a> can be seen in a real-life conversation we recorded with a grandfather with hearing loss and his extended family while having afternoon tea.</p> <p>After the older man has ongoing trouble hearing his granddaughters, his wife teases him with the question “You got your hearing aids in Grandpa?”, which receives laughter from his son and granddaughters.</p> <p>While this sort of teasing might seem light-hearted, it can cause someone with hearing loss to feel embarrassed when they have trouble hearing.</p> <p>A key finding from <a href="https://www.tandfonline.com/doi/full/10.1080/14992027.2024.2406885">our interview research</a> was that adults with hearing loss respond to experiences of stigma by not telling others about their hearing loss.</p> <p>Similarly, in an international <a href="https://www.tandfonline.com/doi/full/10.1080/14992027.2023.2293651">survey of 331 adults</a> with hearing loss, the results of which are yet to be published in a peer-reviewed journal, one in four had not told anyone about their hearing loss. Others only told certain people in specific circumstances.</p> <p>There might, therefore, be family and friends at your Christmas gatherings facing the challenges of hearing loss without anyone knowing.</p> <h2>Supporting loved ones with hearing loss this Christmas</h2> <p>For adults with hearing loss, experiences of stigma can cause them to start to withdraw from social situations, participate less in conversations, and become more <a href="https://journals.lww.com/psychosomaticmedicine/abstract/2013/02000/social_isolation_and_loneliness__relationships.9.aspx">socially isolated and lonely</a>.</p> <p>But a greater awareness about hearing loss and inclusive communication can help tackle the stigma. Here are some simple ways you can be more inclusive of people with hearing loss this festive season:</p> <ol> <li> <p>Think about the location of your event – how noisy is it? When possible, choose restaurants and social settings that are quieter. Outdoor settings will generally be less noisy than indoor ones (apps such as <a href="https://theambientmenu.com.au/">The Ambient Menu</a> can help you choose).</p> </li> <li> <p>Turn down background noise if you can (for example, TV, radio, music).</p> </li> <li> <p>Speak face-to-face as much as possible. This allows for lip-reading so that people are not just reliant on their hearing. If you know someone has difficulty hearing, move closer to them and talk clearly and slightly more slowly.</p> </li> <li> <p>Arrange seating in a way that allows everyone to face each other. Round tables are best.</p> </li> <li> <p>Give people the opportunity to choose where they are seated around a table or in a restaurant. Adults with hearing loss may position themselves in the middle of a table or next to specific people they need to hear.</p> </li> <li> <p>If you are at an event with speeches, use a microphone when possible.</p> </li> <li> <p>If you notice a person not joining in the conversation you could ask them if they can hear OK and, if not, what you can do to help.<!-- Below is The Conversation's page counter tag.

George Clooney's heartfelt message after sad loss

<p>George Clooney has shared a heartfelt message to his <em>Ocean's Eleven </em>co-star, Scott L. Schwartz, who sadly passed away aged 65. </p> <p>"I'm sorry to hear that Scott is gone," he told <em>Variety</em>. </p> <p>"We did three films together and I've never been so gently punched," Clooney continued. </p> <p>"He was a gentle soul and he will be dearly missed."</p> <p>Schwartz, who stood at six feet and 10 inches (approx. 208.3cm) tall, played Bruiser in the <em>Ocean's Eleven </em>trilogy, alongside Clooney, Matt Damon, Brad Pitt, Julia Roberts and more Hollywood stars. </p> <p>Clooney's character in the film, Danny Ocean, hires Bruiser to pretend to beat him up during the group's casino heist. </p> <p>Schwartz's wife Misty confirmed he died on November 26 at his Covington, Los Angeles home, according to <em>People</em>. His cause of death is understood to be congestive heart failure. </p> <p>Misty said while he was known for the Ocean's film, she was "most proud of his charity work", which saw him be honoured with the Glass Slipper Award from children's healthcare foundation CHOC.</p> <p>"Most people associate Scott with the movies, but those who know him personally associated him with being a jolly person, so full of life, a strong loving person, foodie and travel aficionado," his wife told <em>People.</em></p> <p><em>"Life won't be the same without him."</em></p> <p>Schwartz is survived by his wife, Misty, and children Angela and Adam.</p> <p><em>Image: SplashNews.com/ Shutterstock Editorial</em></p> <p> </p>

New study suggests weight loss drugs like Ozempic could help with knee pain. Here’s why there may be a link

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/giovanni-e-ferreira-1030477">Giovanni E. Ferreira</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/christina-abdel-shaheed-425241">Christina Abdel Shaheed</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>The drug semaglutide, commonly known by the brand names Ozempic or Wegovy, was <a href="https://theconversation.com/the-rise-of-ozempic-how-surprise-discoveries-and-lizard-venom-led-to-a-new-class-of-weight-loss-drugs-219721">originally developed</a> to help people with type 2 diabetes manage their blood sugar levels.</p> <p>However, researchers have discovered it may help with other health issues, too. Clinical trials show semaglutide can be effective for <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2032183">weight loss</a>, and hundreds of thousands of people around the world are using it <a href="https://theconversation.com/considering-taking-a-weight-loss-drug-like-ozempic-here-are-some-potential-risks-and-benefits-219312">for this purpose</a>.</p> <p>Evidence has also shown the drug can help manage <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2306963">heart failure</a> and <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2403347">chronic kidney disease</a> in people with obesity and type 2 diabetes.</p> <p>Now, a study published in the <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2403664">New England Journal of Medicine</a> has suggested semaglutide can improve knee pain in people with obesity and osteoarthritis. So what did this study find, and how could semaglutide and osteoarthritis pain be linked?</p> <h2>Osteoarthritis and obesity</h2> <p>Osteoarthritis is a common joint disease, affecting <a href="https://www.aihw.gov.au/reports/chronic-musculoskeletal-conditions/osteoarthritis">2.1 million Australians</a>. Most people with osteoarthritis <a href="https://theconversation.com/do-you-have-knee-pain-from-osteoarthritis-you-might-not-need-surgery-heres-what-to-try-instead-236779">have pain</a> and find it difficult to perform common daily activities such as walking. The knee is <a href="https://pubmed.ncbi.nlm.nih.gov/37675071/">the joint most commonly affected</a> by osteoarthritis.</p> <p>Being overweight or obese is a <a href="https://pubmed.ncbi.nlm.nih.gov/25447976/">major risk factor</a> for osteoarthritis in the knee. The link between the two conditions <a href="https://pubmed.ncbi.nlm.nih.gov/26821091/">is complex</a>. It involves a combination of increased load on the knee, <a href="https://www.nature.com/articles/s41413-023-00301-9">metabolic factors</a> such as high cholesterol and high blood sugar, and inflammation.</p> <p>For example, elevated blood sugar levels increase the production of inflammatory molecules in the body, which can damage the cartilage in the knee, and lead to the <a href="https://pubmed.ncbi.nlm.nih.gov/30712918/">development of osteoarthritis</a>.</p> <p>Weight loss is strongly recommended to reduce the pain of knee osteoarthritis in people who are overweight or obese. <a href="https://pubmed.ncbi.nlm.nih.gov/31908149/">International</a> and <a href="https://www.safetyandquality.gov.au/sites/default/files/2024-08/osteoarthritis-knee-clinical-care-standard-2024.pdf">Australian guidelines</a> suggest losing as little as 5% of body weight can help.</p> <p>But losing weight with just diet and exercise can be difficult for many people. <a href="https://pubmed.ncbi.nlm.nih.gov/26180980/">One study</a> from the United Kingdom found the annual probability of people with obesity losing 5% or more of their body weight was less than one in ten.</p> <p>Semaglutide has recently entered the market as a potential alternative route to weight loss. It comes from a class of drugs known as GLP-1 receptor agonists and works by increasing a person’s sense of fullness.</p> <h2>Semaglutide for osteoarthritis?</h2> <p>The rationale for the <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2403664">recent study</a> was that while we know weight loss alleviates symptoms of knee osteoarthritis, the effect of GLP-1 receptor agonists was yet to be explored. So the researchers set out to understand what effect semaglutide might have on knee osteoarthritis pain, alongside body weight.</p> <p>They randomly allocated 407 people with obesity and moderate osteoarthritis into one of two groups. One group received semaglutide once a week, while the other group received a placebo. Both groups were treated for 68 weeks and received counselling on diet and physical activity. At the end of the treatment phase, researchers measured changes in knee pain, function, and body weight.</p> <p>As expected, those taking semaglutide lost more weight than those in the placebo group. People on semaglutide lost around 13% of their body weight on average, while those taking the placebo lost around 3% on average. More than 70% of people in the semaglutide group lost at least 10% of their body weight compared to just over 9% of people in the placebo group.</p> <p>The study found semaglutide reduced knee pain significantly more than the placebo. Participants who took semaglutide reported an additional 14-point reduction in pain on a 0–100 scale compared to the placebo group.</p> <p>This is much greater than the pain reduction in another <a href="https://pubmed.ncbi.nlm.nih.gov/36511925/">recent study</a> among people with obesity and knee osteoarthritis. This study investigated the effects of a diet and exercise program compared to an attention control (where participants are provided with information about nutrition and physical activity). The results here saw only a 3-point difference between the intervention group and the control group on the same scale.</p> <p>The amount of pain relief reported in the semaglutide trial is also larger than that reported with commonly used pain medicines such as <a href="https://pubmed.ncbi.nlm.nih.gov/35442752/">anti-inflammatories</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/35137418/">opioids</a> and <a href="https://www.bmj.com/content/372/bmj.m4825">antidepressants</a>.</p> <p>Semaglutide also improved knee function compared to the placebo. For example, people who took semaglutide could walk about 42 meters further than those on the placebo in a six-minute walking test.</p> <h2>How could semaglutide reduce knee pain?</h2> <p>It’s not fully clear how semaglutide helps with knee pain from osteoarthritis. One explanation may be that when a person loses weight, there’s less stress on the joints, which reduces pain.</p> <p>But recent studies have also suggested semaglutide and other GLP-1 receptor agonists might have <a href="https://www.sciencedirect.com/science/article/pii/S1043661822002651">anti-inflammatory</a> properties, and could even protect against <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6731440/">cartilage wear and tear</a>.</p> <p>While the results of this new study are promising, it’s too soon to regard semaglutide as a “miracle drug” for knee osteoarthritis. And as this study was funded by the drug company that makes semaglutide, it will be important to have independent studies in the future, to confirm the findings, or not.</p> <p>The study also had strict criteria, excluding some groups, such as those taking opioids for knee pain. One in seven Australians seeing a GP for their knee osteoarthritis <a href="https://pubmed.ncbi.nlm.nih.gov/34527976/">are prescribed opioids</a>. Most participants in the trial were white (61%) and women (82%). This means the study may not fully represent the average person with knee osteoarthritis and obesity.</p> <p>It’s also important to consider semaglutide can have a range of <a href="https://theconversation.com/considering-taking-a-weight-loss-drug-like-ozempic-here-are-some-potential-risks-and-benefits-219312">side effects</a>, including gastrointestinal symptoms and fatigue.</p> <p>There are some concerns that semaglutide could reduce <a href="https://www.sciencealert.com/experts-are-concerned-drugs-like-ozempic-may-cause-muscle-loss">muscle mass</a> and <a href="https://www.healthline.com/health-news/ozempic-muscle-mass-loss">bone density</a>, though we’re still learning more about this.</p> <p>Further, it can be difficult to access.</p> <h2>I have knee osteoarthritis, what should I do?</h2> <p>Osteoarthritis is a disease caused by multiple factors, and it’s important to take <a href="https://www.safetyandquality.gov.au/standards/clinical-care-standards/osteoarthritis-knee-clinical-care-standard/information-consumers-osteoarthritis-knee-clinical-care-standard">a multifaceted approach</a> to managing it. Weight loss is an important component for those who are overweight or obese, but so are other aspects of <a href="https://theconversation.com/do-you-have-knee-pain-from-osteoarthritis-you-might-not-need-surgery-heres-what-to-try-instead-236779">self-management</a>.

How hip pain led Sydney karate master to life-changing weight loss journey

<div> <p>Sydney-based karate instructor and personal trainer Glenn Stephenson knows the toll that joint pain and extra weight can take on physical activity. Despite decades of experience as a martial arts coach, Glenn found himself increasingly limited by severe hip pain and unwanted weight gain.</p> </div> <div> <p>In 2021, at 95 kilograms, the 64-year-old’s arthritis and reduced mobility affected not only his work but also his confidence. “I couldn’t move around like I wanted to, and as a master instructor, it felt wrong to be teaching students while carrying so much extra weight,” he admits.</p> </div> <div> <p>Glenn’s pain and discomfort prompted him to make a drastic change. Instead of resorting to extreme dieting, he adopted a more sustainable approach to weight loss to reduce joint and liver inflammation, and regain his mobility. He shed 20 kilograms and now walks four kilometres daily. “I can move better, my mental health has improved, and I feel more capable of guiding my students,” he says.</p> </div> <div> <p>Today, Glenn encourages others struggling with weight to take a balanced approach to fitness and health. “I look the part now, which gives me confidence as a master instructor to show my students that staying active is achievable at any age.”</p> </div> <div> <p>Dietitian Kirby Sorenson, from health platform <a title="https://www.getmosh.com.au/?utm_term=mosh&amp;utm_campaign=Cross_Search_Brand_Mosh&amp;utm_source=paid-search&amp;utm_medium=adwords&amp;utm_content=100740202037&amp;hsa_acc=5792635568&amp;hsa_cam=1701000406&amp;hsa_grp=100740202037&amp;hsa_ad=697110582898&amp;hsa_src=g&amp;hsa_tgt=kwd-295213997936&amp;hsa_kw=mosh&amp;hsa_mt=p&amp;hsa_net=adwords&amp;hsa_ver=3&amp;gclid=CjwKCAiAxKy5BhBbEiwAYiW--5qfGzQVQBG-CmA6baVMEeP5Zmk_oB_GOstA1n2vabFrLzbeDrEEnxoCM4YQAvD_BwE" href="https://www.getmosh.com.au/?utm_term=mosh&amp;utm_campaign=Cross_Search_Brand_Mosh&amp;utm_source=paid-search&amp;utm_medium=adwords&amp;utm_content=100740202037&amp;hsa_acc=5792635568&amp;hsa_cam=1701000406&amp;hsa_grp=100740202037&amp;hsa_ad=697110582898&amp;hsa_src=g&amp;hsa_tgt=kwd-295213997936&amp;hsa_kw=mosh&amp;hsa_mt=p&amp;hsa_net=adwords&amp;hsa_ver=3&amp;gclid=CjwKCAiAxKy5BhBbEiwAYiW--5qfGzQVQBG-CmA6baVMEeP5Zmk_oB_GOstA1n2vabFrLzbeDrEEnxoCM4YQAvD_BwE" data-outlook-id="bc4b923a-a4a3-4af0-80db-e837cd64b4c7">Mosh</a>, is encouraging Australians to ditch the Body Mass Index (BMI) in favour of more modern diagnostics to determine the risk of disease linked to higher body fat, declaring it’s unfairly categorising people as being overweight.</p> </div> <div> <p>Ms Sorenson says knowing your Body Roundness Index (BRI) as well as your Basal Metabolic Rate (BMR) can more accurately predict the risk of diseases like high blood pressure, type 2 diabetes and heart disease because it works out body fat levels based on height and waist circumference, rather than the BMI method which relies on height and weight.</p> </div> <div> <p>“BMI has long been criticised for inaccurately categorising people as overweight or obese because it doesn’t differentiate between those who carry a lot of muscle and individuals with fat in the wrong places,” Ms Sorenson says.</p> </div> <div> <p>“The problem is that it only looks at overall weight, while the BRI focuses on fat held around the abdomen which is the riskiest fat in terms of overall health.</p> </div> <div> <p>Once the BRI is determined, Ms Sorenson says it can help to know your Basal Metabolic Rate, which is largely determined by your total lean mass to help determine a healthy path to maintaining a healthy weight range.</p> </div> <div> <p>“The basal metabolic rate or BMR gives you an idea of how many calories your body burns doing the bare minimum; breathing, blood circulation, brain and nerve function.

Fasting, eating earlier in the day or eating fewer meals – what works best for weight loss?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/hayley-oneill-1458016">Hayley O'Neill</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> and <a href="https://theconversation.com/profiles/loai-albarqouni-452476">Loai Albarqouni</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p>Globally, <a href="https://www.who.int/news-room/fact-sheets/detail/obesity-and-overweight">one in eight people</a> are living with obesity. This is an issue because <a href="https://www.aihw.gov.au/reports/risk-factors/risk-factors-to-health/contents/overweight-and-obesity">excess fat</a> <a href="https://pubmed.ncbi.nlm.nih.gov/27423262/">increases the risk</a> of type 2 diabetes, heart disease and certain cancers.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/33393504/">Modifying your diet</a> is important for managing obesity and preventing weight gain. This might include reducing your calorie intake, changing your <a href="https://pubmed.ncbi.nlm.nih.gov/39143663/">eating patterns</a> and prioritising healthy food.</p> <p>But is one formula for weight loss more likely to result in success than another? Our <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11530941/">new research</a> compared three weight-loss methods, to see if one delivered more weight loss than the others:</p> <ul> <li>altering calorie distribution – eating more calories earlier rather than later in the day</li> <li>eating fewer meals</li> <li>intermittent fasting.</li> </ul> <p>We analysed data from 29 clinical trials involving almost 2,500 people.</p> <p>We found that over 12 weeks or more, the three methods resulted in similar weight loss: 1.4–1.8kg.</p> <p>So if you do want to lose weight, choose a method that works best for you and your lifestyle.</p> <h2>Eating earlier in the day</h2> <p>When our metabolism <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/metabolic-syndrome">isn’t functioning properly</a>, our body can’t respond to the hormone insulin properly. This can lead to weight gain, fatigue and can increase the risk of a number of chronic diseases such as diabetes.</p> <p>Eating later in the day – with a <a href="https://pubmed.ncbi.nlm.nih.gov/23512957/">heavy dinner</a> and late-night snacking – seems to lead to <a href="https://pubmed.ncbi.nlm.nih.gov/33172509/">worse metabolic function</a>. This means the body becomes less efficient at converting food into energy, managing blood sugar and regulating fat storage.</p> <p>In contrast, consuming calories <a href="https://pubmed.ncbi.nlm.nih.gov/31151228/">earlier</a> in the day appears to <a href="https://pubmed.ncbi.nlm.nih.gov/29754952/">improve</a> metabolic function.</p> <p>However, this might not be the case for everyone. Some people naturally have an evening “chronotype”, meaning they wake up and stay up later.</p> <p>People with this chronotype appear to have <a href="https://pubmed.ncbi.nlm.nih.gov/36803075/">less success losing weight</a>, no matter the method. This is due to a combination of factors including genes, an increased likelihood to have a poorer diet overall and higher levels of hunger hormones.</p> <h2>Eating fewer meals</h2> <p><a href="https://pubmed.ncbi.nlm.nih.gov/30700403/">Skipping breakfast</a> is common, but does it hinder weight loss? Or is a <a href="https://pubmed.ncbi.nlm.nih.gov/28967343/">larger breakfast and smaller dinner</a> ideal?</p> <p>While <a href="https://pubmed.ncbi.nlm.nih.gov/28137935/">frequent meals</a> may reduce disease risk, recent studies suggest that compared to eating one to two meals a day, eating six times a day might increase <a href="https://pubmed.ncbi.nlm.nih.gov/32437566/">weight loss success</a>.</p> <p>However, this doesn’t reflect the broader research, which tends to show consuming <a href="https://pubmed.ncbi.nlm.nih.gov/33485709/">fewer meals</a> can lead to greater weight loss. <a href="https://pubmed.ncbi.nlm.nih.gov/39485353/">Our research</a> suggests three meals a day is better than six. The easiest way to do this is by cutting out snacks and keeping breakfast, lunch and dinner.</p> <p>Most studies compare three versus six meals, with limited evidence on whether <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7490164/">two meals is better than three</a>.</p> <p>However, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11530941/">front-loading your calories</a> (consuming most of your calories between breakfast and lunch) appears to be better for weight loss and may also help <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9605877/">reduce hunger</a> across the day. But more studies with a longer duration are needed.</p> <h2>Fasting, or time-restricted eating</h2> <p>Many of us eat over a period of more than <a href="https://pubmed.ncbi.nlm.nih.gov/26411343/">14 hours a day</a>.</p> <p>Eating late at night <a href="https://pubmed.ncbi.nlm.nih.gov/26411343/">can throw off</a> your body’s natural rhythm and alter how your organs function. Over time, this can increase your risk of type 2 diabetes and other chronic diseases, particularly among <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8617838/">shift workers</a>.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/35194176/">Time-restricted eating</a>, a form of intermittent fasting, means eating all your calories within a <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7262456/">six- to ten-hour window</a> during the day when you’re most active. It’s not about changing what or how much you eat, but <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7262456/">when you eat it</a>.</p> <p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7262456/">Animal studies</a> suggest time-restricted eating can lead to weight loss and improved metabolism. But the evidence in humans is still limited, especially about the long-term benefits.</p> <p>It’s also unclear if the benefits of time-restricted eating are due to the timing itself or because people are eating less overall. When we looked at studies where participants ate freely (with no intentional calorie limits) but followed an eight-hour daily eating window, they naturally consumed about 200 fewer calories per day.</p> <h2>What will work for you?</h2> <p>In the past, clinicians have thought about weight loss and avoiding weight gain as a simile equation of calories in and out. But factors such as how we distribute our calories across the day, how often we eat and whether we eat late at night may also impact our metabolism, weight and health.</p> <p>There are no easy ways to lose weight. So choose a method, or combination of methods, that suits you best. You might consider</p> <ul> <li>aiming to eat in an eight-hour window</li> <li>consuming your calories earlier, by focusing on breakfast and lunch</li> <li>opting for three meals a day, instead of six.</li> </ul> <p>The <a href="https://link.springer.com/article/10.1007/s13679-024-00555-2">average adult gains 0.4 to 0.7 kg per year</a>. Improving the quality of your diet is important to prevent this weight gain and the strategies above might also help.</p> <p>Finally, there’s still a lot we don’t know about these eating patterns. Many existing studies are short-term, with small sample sizes and varied methods, making it hard to make direct comparisons.</p> <p>More research is underway, including well-controlled trials with larger samples, diverse populations and consistent methods. So hopefully future research will help us better understand how altering our eating patterns can result in better health.<!-- Below is The Conversation's page counter tag.

"An incredible loss": Quincy Jones dies at age 91

<p>Legendary music producer Quincy Jones, who worked with the likes of Michael Jackson and Frank Sinatra throughout his career, has died at the age of 91. </p> <p>According to a statement from his family, he died on Sunday night at his home in Bel Air surrounded by friends and family. </p> <p>“Tonight, with full but broken hearts, we must share the news of our father and brother Quincy Jones’ passing,” the statement read. </p> <p>“And although this is an incredible loss for our family, we celebrate the great life that he lived and know there will never be another like him.”</p> <p>“He is truly one of a kind and we will miss him dearly; we take comfort and immense pride in knowing that the love and joy, that were the essence of his being, was shared with the world through all that he created. Through his music and his boundless love, Quincy Jones’ heart will beat for eternity.”</p> <p>A pioneer in the music industry, Jones arranged records for Frank Sinatra and Ella Fitzgerald, composed the soundtracks for <em>Roots</em> and <em>In the Heat of the Night</em>, produced Michael Jackson's iconic album <em>Thriller</em>, and oversaw the all-star recording of <em>We Are the World</em>: the 1985 charity record for famine relief in Africa.</p> <p>Dozens of movie and music stars have paid tribute to Jones, such as American singer and pianist Harry Connick Jr., who said that Jones was his "hero".</p> <p>“My hero. truly one of the greatest minds the music world has ever known. he was so kind to me, so wonderful, such an influence. his legacy and his music will live forever. thank you for everything, Q. you were the dude,” he wrote on Instagram.</p> <p>Acting icon Morgan Freeman said the producer had "left an enduring legacy" behind.</p> <p>"Today, we say goodbye to the legendary Quincy Jones – a musical giant whose genius reshaped our world and left an enduring legacy. Rest well, Quincy."</p> <p>Actor Colman Domingo recalled meeting Jones in a personal message, writing, “He asked, where are you from? Philly I replied, his eyes twinkled and he talked about the Uptown Theatre. I was so thrilled to meet Mr. American Music himself. I literally kneeled because he was a King. Thank you Mr. Quincy Jones for giving us all the sound."</p> <p><em>Image credits: John Salangsang/Shutterstock Editorial </em></p>

Trying to lose weight? Here’s why your genetics could be just as important as your exercise regime

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/henry-chung-1279176">Henry Chung</a>, <a href="https://theconversation.com/institutions/university-of-essex-1291">University of Essex</a>; <a href="https://theconversation.com/profiles/chris-mcmanus-2226445">Chris McManus</a>, <a href="https://theconversation.com/institutions/university-of-essex-1291">University of Essex</a>, and <a href="https://theconversation.com/profiles/sally-waterworth-2226444">Sally Waterworth</a>, <a href="https://theconversation.com/institutions/university-of-essex-1291">University of Essex</a></em></p> <p>Weight loss is a complicated process. There are so many factors involved including your diet, how much sleep you get each night and the kind of exercise you do. Our recent study shows that your <a href="https://www.tandfonline.com/doi/full/10.1080/02701367.2024.2404981">specific genetic profile</a> may also have a dominant effect on how well you lose weight through exercise. This might explain why two people who do an identical workout will see very different results.</p> <p>We identified 14 genes that appeared to significantly contribute to how much weight a person lost through running. This suggests that some of us have a natural talent when it comes to burning fat and losing weight through exercise.</p> <p>To conduct our study, we recruited 38 men and women born in the UK aged between 20 and 40. None of the participants regularly exercised at the start of the study. The group was randomly divided, with one half following a strict eight-week endurance programme that consisted of three weekly runs of 20-30 minutes.</p> <p>The other group acted as a <a href="https://www.britannica.com/science/control-group">control</a>. They were instructed to refrain from exercise and continue their daily routines as normal over this study period, including diet and lifestyle habits.</p> <p>All participants conducted a running test to see how far they could run in 12 minutes, and were weighed before and after the study period. This was to gauge their initial fitness level and see how much they changed over the duration of the study. <a href="https://www.nhs.uk/conditions/obesity/">Body mass index</a> (BMI) was also calculated.</p> <p>Additionally, a saliva sample was collected from each person with a <a href="https://muhdo.com/?gclid=Cj0KCQjwiIOmBhDjARIsAP6YhSUB3WI81JP4Q_snYLhh-SBVNeCJNy2m63C8bKJFvO-nJ5UsHuCCdqMaAhTeEALw_wcB">DNA test kit</a> at the end of the study to assess their unique genetic profile.</p> <p>It’s important to note that everyone who participated in the study had a similar body weight, BMI and aerobic fitness level at the start of the study. This is beneficial for <a href="https://casp-uk.net/news/homogeneity-in-research/">multiple reasons</a>. It meant everyone was at the same starting point, and some <a href="https://www.sciencedirect.com/topics/nursing-and-health-professions/confounding-variable">confounding variables</a> were already controlled for such as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10128125/">fitness level</a>. This ultimately improves accuracy in interpreting the results.</p> <h2>Exercise genes</h2> <p>Everyone in the exercise group managed to lose weight – around 2kg on average. The control group, on the other hand, put on a little bit of weight.</p> <p>While a 2kg weight loss may not sound like a lot, it’s significant considering the exercise regime only lasted eight weeks and participants made no <a href="https://www.intechopen.com/chapters/87186">changes to their diet</a>.</p> <p>More significant, however, was the large variation in results among those that exercised – with an up to 10kg difference in weight loss between some of the participants. In fact, everyone within the exercise group improved at different rates.</p> <p>Since we controlled for factors such as the <a href="https://pubmed.ncbi.nlm.nih.gov/3529283/">intensity, duration and frequency</a> of the exercises and used participants who’d had a similar body weight and fitness level at the start of the study, this suggests that some people naturally benefited more than others from endurance training.</p> <p>When we looked at the genetic profiles of our participants, we found that differences in each person’s response to the exercise was strongly associated with their specific genetics.</p> <p>We showed there was a strong linear correlation between the amount of weight participants lost and 14 genes that have previously been shown to be associated with body weight, metabolism or <a href="https://www.nature.com/articles/s41380-018-0017-5">psychological conditions</a> that affect BMI. The greater number of these genes a participant had, the more weight they lost. Our results also revealed that around 63% of the variance in weight lost among participants were explained by the genes identified.</p> <p>For example, research has shown the <a href="https://www.ncbi.nlm.nih.gov/gene/10891">PPARGC1A gene</a> plays a role in metabolism and the <a href="https://link.springer.com/article/10.1007/S11033-020-05801-Z">use of fats for energy</a> while exercising. Our study found that all participants who lost more than 1.5kg from exercise had this gene. Those who lost less than this did not have this gene.</p> <p>Our findings align with what <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0249501&amp;s2=P875440273_1683331208925004155">previous studies</a> have shown. But while previous papers have only looked at the link between individual genes and weight loss, ours is the first to show that 14 different genes appear to work in combination to affect whether a person loses weight from endurance exercise.</p> <h2>Piece of the puzzle</h2> <p>Our study also suggests that while some people possess genes that make it easier for them to get fit and lose weight, people with these favourable genetics can only flourish if they actually exercise. In fact, our control group also had a number of these listed genes, but without exercise these genes could not activate, and so the participants did not lose any weight.</p> <p>While our study provides compelling findings, it’s not without limitations. Since we only looked at endurance-based exercise, it will be important for future studies to investigate whether there are similar links between weight loss, genetics and combinations of different types of training (such as a mixture of endurance and strength sessions into a training plan).</p> <p>It’s also worth mentioning that exercise is only <a href="https://www.who.int/activities/controlling-the-global-obesity-epidemic">one piece of the puzzle</a> when it comes to weight loss. So even if you have all 14 of these genes, you won’t lose any weight or get fit if you don’t exercise and maintain a healthy diet and sleep pattern.</p> <p>On the flip side, someone that only has a few of these favourable genes can still benefit if they exercise and are mindful of other aspects of their lifestyle.<!-- Below is The Conversation's page counter tag.

How do heat protectants for hair work? A chemistry expert explains

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/daniel-eldridge-1494633">Daniel Eldridge</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>Heat can do amazing things to change your hairstyle. Whether you’re using a curling wand to get ringlets, a flat iron to straighten or a hair dryer to style, it’s primarily the heat from these tools that delivers results.</p> <p>This comes with casualties. While your hair is surprisingly tolerant to heat compared with many other parts of your body, it can still only withstand so much. Heat treatment hair appliances frequently operate at over 150°C, with some reportedly <a href="https://www.frontiersin.org/journals/bioengineering-and-biotechnology/articles/10.3389/fbioe.2019.00298/full#B13">reaching</a> <a href="https://www.researchgate.net/publication/289291195_Thermal_degradation_of_hair_I_Effect_of_curling_irons">over 200°C</a>. At these temperatures, your hair can end up fried.</p> <p>Many people use heat protectants, often in the form of sprays, to minimise the damage. So how do these protectants work? To answer that, I first have to explain exactly what heat does to your tresses on the molecular level.</p> <h2>What heat does to your hair</h2> <p>A large proportion of your hair is made up of proteins. There are attractive forces between these proteins, known as hydrogen bonds. These bonds play a big role in dictating the shape of your locks.</p> <p>When you heat up your hair, the total attraction of these hydrogen bonds become weaker, allowing you to more easily re-shape your hair. Then, when it cools back down, these attractions between the proteins are re-established, helping your hair hold its new look until the proteins rediscover their normal structure.</p> <p>The cuticle – the outermost protective layer of your hair – contains overlapping layers of cells that lose integrity when they’re heated, damaging this outer protective layer.</p> <p>Inside that outer layer is the cortex, which is rich in a protein called keratin.</p> <p>Many proteins don’t <a href="https://pubmed.ncbi.nlm.nih.gov/21635854/">hold up structurally</a> after intense heating. Think of cooking an egg – the change you see is a result of the heat altering the proteins in that egg, unravelling them into different shapes and sizes.</p> <p>It’s a <a href="https://library.scconline.org/v049n04/33">similar story</a> when it comes to heating your hair. The proteins in your hair are also susceptible to heat damage, reducing the overall strength and integrity of the hair.</p> <p>Heat can also affect substances called melanin and <a href="https://pubmed.ncbi.nlm.nih.gov/21443842/">tryptophan</a> in your hair, resulting in a change in pigmentation. Heat-damaged hair is <a href="https://pubmed.ncbi.nlm.nih.gov/21635854/">harder to brush</a>.</p> <p>The damage is even more devastating if you use heat styling tools such as <a href="https://labmuffin.com/why-you-should-never-straighten-or-curl-wet-hair/">curling irons or straighteners</a> to <a href="https://library.scconline.org/v062n01/23">heat wet hair</a>, as at the high treatment temperatures, the water soaked up by the fibres can violently evaporate.</p> <p>The result of this is succinctly described by science educator and cosmetic chemist Michelle Wong, also known as <a href="https://labmuffin.com/how-do-heat-protectant-hair-products-work/">Lab Muffin</a>. She notes if you heat wet hair this way, “steam will blast through your hair’s structure”.</p> <p>This steam bubbling or bursting through the hair can <a href="https://pubmed.ncbi.nlm.nih.gov/21443842/">cause substantial damage</a>.</p> <p>It’s worth noting hair dryers don’t concentrate heat in the same way as styling tools such as flat irons or curling wands, but you still need to move the hair dryer around constantly to avoid heat building up in one spot and causing damage.</p> <p>Once heat damage is done, regardless of whether it is severe or mild, the best remaining options are symptom management or a haircut.</p> <p>For all of these reasons, when you’re planning to heat treat your hair, protection is a good idea.</p> <h2>How hair protectants work</h2> <p>When you spray on a hair protectant, many possible key ingredients can go to work.</p> <p>They can have <a href="https://library.scconline.org/v062n01/15">daunting-looking names</a> like polyvinyl pyrrolidone, methacrylates, polyquaterniums, silicones and more.</p> <p>These materials are chosen because they readily stick onto your hair, creating a coating, a bit like this:</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=225&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=225&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=225&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=283&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=283&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=283&amp;fit=crop&amp;dpr=3 2262w" alt="A cartoon of coating attached to a strand of hair." /></a><figcaption><span class="caption">Hair protectant applies a coating to your hair.</span> <span class="attribution"><span class="source">Author provided</span></span></figcaption></figure> <p>This coating is a protective layer;

Is stress turning my hair grey?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/theresa-larkin-952095">Theresa Larkin</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a></em></p> <p>When we start to go grey depends a lot on <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">genetics</a>.</p> <p>Your first grey hairs <a href="https://elifesciences.org/articles/67437">usually appear</a> anywhere between your twenties and fifties. For men, grey hairs <a href="https://pubmed.ncbi.nlm.nih.gov/22077870/">normally</a> start at the temples and sideburns. Women tend to start greying on the hairline, especially at the front.</p> <p>The most <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">rapid greying</a> usually happens between ages 50 and 60. But does anything we do speed up the process? And is there anything we can do to slow it down?</p> <p>You’ve probably heard that plucking, dyeing and stress can make your hair go grey – and that redheads don’t. Here’s what the science says.</p> <h2>What gives hair its colour?</h2> <p>Each strand of hair is produced by a hair follicle, a tunnel-like opening in your skin. Follicles contain two different kinds of <a href="https://www.sciencedirect.com/science/article/pii/S1534580720301040">stem cells</a>:</p> <ul> <li>keratinocytes, which produce <a href="https://my.clevelandclinic.org/health/body/23204-keratin">keratin</a>, the protein that makes and regenerates hair strands</li> <li>melanocytes, which produce <a href="https://my.clevelandclinic.org/health/body/22615-melanin">melanin</a>, the pigment that colours your hair and skin.</li> </ul> <p>There are <a href="https://www.ncbi.nlm.nih.gov/books/NBK459156/">two main types</a> of melanin that <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">determine hair colour</a>. Eumelanin is a black-brown pigment and pheomelanin is a red-yellow pigment.</p> <p>The <a href="https://theconversation.com/studying-the-complex-genetics-behind-hair-colour-reveals-how-melanin-affects-us-171088#:%7E:text=Eumelanin%20is%20also%20known%20as%20the%20brown-black%20pigment%2C,is%20due%20to%20low%20amounts%20of%20both%20pigments.">amount of the different pigments</a> determines hair colour. Black and brown hair has mostly eumelanin, red hair has the most pheomelanin, and blonde hair has just a small amount of both.</p> <h2>So what makes our hair turn grey?</h2> <p>As we age, it’s normal for cells to become less active. In the hair follicle, this means stem cells produce less melanin – turning our hair grey – and less keratin, causing hair thinning and loss.</p> <p>As less melanin is produced, there is less pigment to give the hair its colour. Grey hair has very little melanin, while white hair has none left.</p> <p>Unpigmented hair <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6290285/">looks grey</a>, white or silver because light reflects off the keratin, which is pale yellow.</p> <p>Grey hair is thicker, coarser and stiffer than hair with pigment. This is because the shape of the hair follicle becomes <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6290285/">irregular</a> as the stem cells change with age.</p> <p>Interestingly, grey hair also grows faster than pigmented hair, but it <a href="https://elifesciences.org/articles/67437">uses more energy</a> in the process.</p> <h2>Can stress turn our hair grey?</h2> <p>Yes, stress can <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6290285/">cause your hair to turn grey</a>. This happens when <a href="https://faseb.onlinelibrary.wiley.com/doi/epdf/10.1096/fj.05-4039fje">oxidative stress</a> damages hair follicles and stem cells and <a href="https://www.frontiersin.org/journals/physiology/articles/10.3389/fphys.2022.839859/full">stops them producing</a> melanin.</p> <p>Oxidative stress is an imbalance of too many damaging free radical chemicals and not enough protective antioxidant chemicals in the body. It can be <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">caused by</a> psychological or emotional stress as well as autoimmune diseases.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/22077870/">Environmental factors</a> such as exposure to UV and pollution, as well as smoking and some drugs, can also play a role.</p> <p>Melanocytes are <a href="https://elifesciences.org/articles/67437">more susceptible to damage</a> than keratinocytes because of the complex steps in melanin production. This explains why ageing and stress usually cause hair greying before hair loss.</p> <p>Scientists have been able to link less pigmented sections of a hair strand to <a href="https://elifesciences.org/articles/67437">stressful events in a person’s life</a>. In younger people, whose stems cells still produced melanin, colour returned to the hair after the stressful event passed.</p> <h2>4 popular ideas about grey hair – and what science says</h2> <p><strong>1. Does plucking a grey hair make more grow back in its place?</strong></p> <p>No. When you pluck a hair, you might notice a small bulb at the end that was attached to your scalp. This is the <a href="https://my.clevelandclinic.org/health/body/23435-hair-follicle">root</a>. It grows from the hair follicle.</p> <p>Plucking a hair pulls the root out of the follicle. But the follicle itself is the opening in your skin and can’t be plucked out. Each hair follicle can only grow a single hair.</p> <p>It’s possible frequent plucking could make your hair <a href="https://pubmed.ncbi.nlm.nih.gov/18713071/">grey earlier</a>, if the cells that produce melanin are damaged or exhausted from too much regrowth.</p> <p><strong>2. Can my hair can turn grey overnight?</strong></p> <p>Legend says Marie Antoinette’s hair went <a href="https://www.healthline.com/health/marie-antoinette-syndrome">completely white</a> the night before the French queen faced the guillotine – but this is a myth.</p> <p>Melanin in hair strands is chemically stable, meaning it can’t transform instantly.</p> <p>Acute psychological stress does rapidly deplete melanocyte stem cells <a href="https://www.nature.com/articles/s41586-020-1935-3">in mice</a>. But the effect doesn’t show up immediately. Instead, grey hair becomes visible as the strand grows – at a rate of <a href="https://www.medicalnewstoday.com/articles/326764">about 1 cm per month</a>.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7432488/">Not all hair</a> is in the growing phase at any one time, meaning it can’t all go grey at the same time.</p> <p><strong>3. Will dyeing make my hair go grey faster?</strong></p> <p>This <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9953601/">depends on the dye</a>.</p> <p>Temporary and semi-permanent dyes should not cause early greying because they just coat the hair strand without changing its structure. But permanent products cause a chemical reaction with the hair, using an oxidising agent such as hydrogen peroxide.</p> <p>Accumulation of hydrogen peroxide and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10232955/">other hair dye chemicals</a> in the hair follicle <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">can damage</a> melanocytes and keratinocytes, which can cause greying and hair loss.</p> <p><strong>4. Is it true redheads don’t go grey?</strong></p> <p>People with red hair also lose melanin as they age, but differently to those with black or brown hair.</p> <p>This is because the red-yellow and black-brown pigments are chemically different.</p> <p>Producing the brown-black pigment eumelanin is more complex and <a href="https://onlinelibrary.wiley.com/doi/full/10.1034/j.1600-0749.2002.02017.x">takes more energy</a>, making it more susceptible to damage.</p> <p>Producing the red-yellow pigment (pheomelanin) causes <a href="https://www.sciencedirect.com/science/article/pii/S016953472030375X">less oxidative stress</a>, and is more simple. This means it is easier for stem cells to continue to produce pheomelanin, even as they reduce their activity with ageing.</p> <p>With ageing, red hair tends to fade into strawberry blonde and silvery-white. Grey colour is due to less eumelanin activity, so is more common in those with black and brown hair.</p> <p>Your genetics determine when you’ll start going grey. But you may be able to avoid premature greying by staying healthy, reducing stress and avoiding smoking, too much alcohol and UV exposure.</p> <p>Eating <a href="https://www.healthline.com/health/melanin-in-hair#b-6-and-b-12">a healthy diet</a> may also help because vitamin B12, copper, iron, calcium and zinc all <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6290285/">influence melanin production and hair pigmentation</a>.<!-- Below is The Conversation's page counter tag.

Ozempic, Wegovy, Rybelsus: Are we losing sight of overall health? Here’s what the science says

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/aude-bandini-1488512">Aude Bandini</a>, <a href="https://theconversation.com/institutions/universite-de-montreal-1743">Université de Montréal</a>; <a href="https://theconversation.com/profiles/jean-philippe-drouin-chartier-1533338">Jean-Philippe Drouin-Chartier</a>, <a href="https://theconversation.com/institutions/universite-laval-1407">Université Laval</a>; <a href="https://theconversation.com/profiles/pierre-marie-david-1375228">Pierre-Marie David</a>, <a href="https://theconversation.com/institutions/universite-de-montreal-1743">Université de Montréal</a>, and <a href="https://theconversation.com/profiles/remi-rabasa-lhoret-1533515">Rémi Rabasa-Lhoret</a>, <a href="https://theconversation.com/institutions/universite-de-montreal-1743">Université de Montréal</a></em></p> <p>The craze for new drugs in the GLP-1 (Glucagon-like peptide 1) and GIP (Gastric inhibitory polypeptide) analogue class, better known under the trade names Ozempic and Wegovy, is remarkable, but it’s not totally unprecedented in the history of pharmaceutical blockbusters.</p> <p>The volume of prescriptions and the budget allocated to them by public health insurance schemes are exploding, as are the <a href="https://www.forbes.com/sites/roberthart/2024/05/02/ozempic-maker-novo-nordisk-beats-profit-forecasts-amid-weight-loss-drug-frenzy/">profits of the companies that manufacture them</a>.</p> <p>Part of the popularity of these drugs owes to social networks, but these are not always the best source for health information. When it comes to the subject of weight loss, both fantasy and prejudice come into play. This works to the detriment of everyone’s well-being, but particularly those who are already stigmatized.</p> <p>As specialists in the philosophy of medicine (Université de Montréal), nutrition and food science (Université Laval), the sociology of medication (Université de Montréal) and endocrinology (Institut de recherches cliniques de Montréal), we feel it’s necessary to step back and take stock of both the promises and the limitations of these new treatments.</p> <h2>The best of both worlds</h2> <p>GLP-1/GIP analogues were originally developed to regulate glycemia (blood sugar levels) in people with Type 2 diabetes, thereby preventing the complications associated with this disease. When studies were carried out to assess their safety and efficacy, it was discovered that these drugs also led to weight loss. This prompted new research which showed that at higher doses, the drugs could lead to <a href="https://pubmed.ncbi.nlm.nih.gov/38078870/">very significant weight loss</a>, from 15 to 25 per cent of the starting weight.</p> <p>The mode of action of these drugs on blood sugar regulation is clear: they simulate incretin hormones which, in turn, increase insulin secretion. Weight loss, on the other hand, was only explained after the fact: in addition to the pancreas, these molecules also act on the brain by regulating the sensation of satiety and, indirectly, on the stomach by slowing gastric emptying. These two combined effects reduce appetite and lead to weight reduction.</p> <p>This is how a new use for the drug appeared, at which point the company Novo Nordisk began marketing the same drug under two different names: Ozempic to treat Type 2 diabetes, and <a href="https://theconversation.com/considering-taking-wegovy-to-lose-weight-here-are-the-risks-and-benefits-and-how-it-differs-from-ozempic-237308">Wegovy to manage obesity</a>.</p> <h2>A new era</h2> <p>GLP-1/GIP analogues are a welcome therapeutic breakthrough at a time when the <a href="https://www.diabetes.ca/advocacy---policies/advocacy-reports/national-and-provincial-backgrounders/diabetes-in-canada">prevalence of Type 2 diabetes</a> and <a href="https://www.statcan.gc.ca/o1/en/plus/5742-overview-weight-and-height-measurements-world-obesity-day">obesity</a> is exploding and affecting people younger and younger.</p> <p>These diseases particularly affect women, members of racialized groups and socio-economically disadvantaged populations. The physical and mental suffering these cause and the costs associated with treating them are both considerable. So the arrival of new weapons in the therapeutic arsenal is a source of hope.</p> <p>Draconian changes in lifestyle are certainly effective. But they are very difficult to implement and maintain over time for reasons that go beyond the individual sphere; on the one hand, genetic predisposition plays a major role in the development of Type 2 diabetes and obesity; on the other, because these conditions are <a href="https://obesitycanada.ca/managing-obesity/">multifactorial</a>, management of them must be comprehensive to be effective and long lasting: it must combine medical interventions but also nutritional, functional, psycho-social, environmental and even institutional interventions.</p> <p>Support services of this kind do exist, but only in large university hospital centres to which many people do not have access. Nor do many people have easy access to <a href="https://health-infobase.canada.ca/health-inequalities/index">healthy and varied food options</a>, sports facilities or social and psychological support.</p> <h2><strong>Treating the effects but not the causes</strong></h2> <p>To be effective over the long term, GLP-1/GIP analogues must be taken continuously: without drastic lifestyle changes, the <a href="https://pubmed.ncbi.nlm.nih.gov/35441470/">weight that was lost is regained within a year of stopping</a>, and glycemic control is compromised once again.</p> <p>In other words, the drugs treat the effects of Type 2 diabetes and obesity but not their causes. And yet some of these causes are modifiable: for example, according to <a href="https://www150.statcan.gc.ca/n1/pub/75-006-x/2023001/article/00013-eng.htm">Statistics Canada</a>, less than half the Canadian population (49.2 per cent for adults; 43.9 per cent for young people and children) achieves the recommended amount of weekly physical activity. According to the same source, <a href="https://www150.statcan.gc.ca/n1/pub/75-006-x/2023001/article/00013-eng.htm">food insecurity</a> affects around 14 per cent of the Québec population (22 per cent in Alberta).</p> <p>Pharmacological treatment, even if it allows an individual to eat less, does not necessarily mean that person will <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10837702/">eat better</a>. Similarly, losing weight does not mean one will become more active or healthier. So these new drugs do not cure Type 2 diabetes or obesity. Nor do they prevent these diseases from developing, although they do help to limit the many complications to which they give rise.</p> <h2><strong>Prescribe and treat</strong></h2> <p>A drug such as Mounjaro is as effective at weight loss as bariatric surgery. Much easier to administer and much less risky, it could be a real game changer in the treatment of obesity. Prescribed directly by family doctors and dispensed in pharmacies, it would also be much more accessible and easier to administer for those who need it.</p> <p>This raises the question of costs and reimbursement, but not only that: prescribing is not the same as treating. Here, the manufacturers are following the recommendations of the health authorities: this treatment must be preceded by a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10748770/">careful assessment</a>, then management, and above all a close and regular monitoring of diet, physical activity, mental health, and if necessary, socio-economic assistance.</p> <p>This requires not only time that GPs do not have, but also co-ordination with other players in the health-care network. The problem is not whether the treatment will be effective, but what can happen if it is. Losing 25 per cent of your body weight in just a few months has serious consequences, which are not always beneficial: it involves a loss of body fat, but also of muscle mass, which is associated with intense fatigue. Nor should we underestimate the <a href="https://pubmed.ncbi.nlm.nih.gov/37990685/">challenge of adapting physically and psychologically</a> to a body transformation of this scale. Losing weight doesn’t solve everything, and expectations must remain realistic.</p> <h2>What lessons can we learn?</h2> <p>The clinical effectiveness of GLP-1/GIP analogues in reducing the complications associated with Type 2 diabetes and obesity is indisputable. However, these drugs are not suitable for everyone, and they are certainly not miracle cures that will make it possible for one to regain health without making any changes to lifestyle or environment.</p> <p>We must bear in mind that their success, both commercial and medical, is also the result of a failure: that of our societies to prevent these diseases, to promote healthy lifestyles and to develop environments conducive to the health of all.<!-- Below is The Conversation's page counter tag.

How to revive your curls without paying salon prices

<p>Maintaining curly hair takes a lot of time and effort and sometimes no matter what you do, the frizz just cannot be tamed. </p> <p>While getting your hair done at the salon can be a treat, having to pay salon prices to get softness, shine and definition for your curls is just not sustainable in the long run. </p> <p>Enter <a href="https://www.johnfrieda.com/en-au/home/" target="_blank" rel="noopener">John Frieda</a>'s newest Frizz Ease Miraculous Recovery range, which is now infused with repairing ceramides designed to transform frizzy and damaged hair. </p> <p>The Miraculous Recovery Repairing shampoo and conditioner are two of my personal faves, as I could feel the difference in how soft my hair felt after the first use.</p> <p>Not only are the products safe for colour-treated hair, they also made my curls more manageable and easy to style, with the effects lasting for two days, which is amazing considering how quickly my curls can go limp. </p> <p>I also loved how subtle the scent was, and found the most effective way of applying the conditioner was to comb it through my hair with a detangling brush in the shower, as it helps distribute the product evenly. </p> <p>While different curls all need slightly different care, I found the shampoo provided the perfect balance of cleaning build-up on my hair without leaving it dry or flaky. </p> <p>The star of the range was definitely the All-in-1 extra strength serum, which provided extra protection for my colour-treated and chemically treated hair. I love that you can apply this product through wet or dry hair, and it was the perfect way to revive my curls. </p> <p>The Finishing Creme was a bit too thick for my fine, curly hair, but for those with tighter curls or  those looking for some extra moisture during more humid days, a light layer of the product would surely tame any flyaways or frizz. </p> <p>With most of their products retailing for around $20 it is an affordable solution to bringing life back into colour-treated and damaged curls. The product can be found in all major supermarkets and pharmacies across <a href="https://www.chemistwarehouse.com.au/shop-online/5571/john-frieda-haircare" target="_blank" rel="noopener">AU</a> and <a href="https://www.chemistwarehouse.co.nz/shop-online/5571/john-frieda-haircare" target="_blank" rel="noopener">NZ</a>. </p> <p><em>Images: Supplied</em></p> <p> </p>

Jelena Dokic's powerful message on body image

<p>Jelena Dokic has shared a powerful message about body image, after years of online trolls commenting on her weight. </p> <p>The tennis great took to Instagram to share before and after photos of her from nine months ago with the caption: "NOW THE SAME PERSON REGARDLESS OF MY SIZE".</p> <p>"Whether 30 kilos more on the left 10 months ago or now. Proud of myself in exactly the same way," she said.</p> <p>"Because my size and number on the scale doesn't define me.</p> <p>"My kindness, hard work, humility, loyalty, good heart, resilience, strength in face adversity and fighting spirit does. And that's what really matters."</p> <p>"Nobody at your funeral will ever talk about your size," Dokic continued.</p> <p>"They will talk about who you were as a person. So make sure they can say what an amazing and kind person you were. And that's what it's about. Legacy of kindness and being a good person.</p> <p>"And if you do it at a size 20 or a size 2, it really doesn't matter. But don't ever judge anyone and don't ever base your opinion on others based on their size.</p> <p>"Because then you are just not a good person and it's not kind."</p> <p>She then urged her followers to be kind before saying that she is not ashamed of who she was "because it doesn't matter what size I am as long as I am a good person."</p> <p>She continued saying that no matter what size she is "nobody will shame me into feeling bad about myself and who I am especially nobody that sits behind a keyboard or phone and takes time out of their life to write something negative to someone else especially someone that you don't even know." </p> <p>"And the same goes if you see me or anyone else in person and you judge us and base your opinion of us based on our size," she said.</p> <p>"That's just terrible. And what you think of me and others based on size says everything about you. Full stop."</p> <p>Dokic has been a vocal advocate for body positivity, after years of online trolls commenting on her changing body size. </p> <p>Just last month she opened up about her <a href="https://www.oversixty.com.au/health/body/jelena-dokic-s-candid-admission-on-weight-loss" target="_blank" rel="noopener">body transformation </a>and struggles with depression and an eating disorder. </p> <p><em>Images: Instagram</em></p>
