How social media can 'trigger' eating disorders in young people
Social media can push vulnerable young people towards developing eating disorders by glorifying thinness and promoting fake, dangerous advice about diet and nutrition, experts warn.
Young women and girls are much more likely to suffer from illnesses such as anorexia, bulimia and binge eating disorder, though rates among men have been increasing.
Research has shown the percentage of people worldwide who have had some kind of eating disorder during their lives rose from 3.5 percent in 2000 to 7.8 percent in 2018, a timeframe that captures the rise of social media.
For the professionals trying to help teenagers recover from these disorders, misinformation from influencers on platforms such as TikTok and Instagram is a huge problem.
"We no longer treat an eating disorder without also addressing social media use," French dietitian and nutritionist Carole Copti told AFP. "It has become a trigger, definitely an accelerator and an obstacle to recovery."
The causes of eating disorders are complex, with psychological, genetic, environmental and social factors all having the potential to make someone more susceptible.
Social media "is not the cause but the straw that may break the camel's back," said Nathalie Godart, a psychiatrist for children and adolescents at the Student Health Foundation of France.
By promoting thinness, strictly controlled diets and relentless exercise, social media weakens already vulnerable people and "amplifies the threat" to their health, she told AFP.
Just one recent example is the #skinnytok trend, a hashtag on TikTok full of dangerous and guilt-inducing advice encouraging people to drastically reduce how much food they eat.
For Charlyne Buigues, a French nurse specializing in eating disorders, social media serves as a gateway to these problems, which are "normalized" online.
She condemned videos showing young girls with anorexia exposing their malnourished bodies -- or others with bulimia demonstrating their "purges".
"Taking laxatives or vomiting are presented as a perfectly legitimate way to lose weight, when actually they increase the risk of cardiac arrest," Buigues said.
Eating disorders can damage the heart, cause infertility and other health problems, and have been linked to suicidal behavior.
Anorexia has the highest rate of death of any psychiatric disease, research has found. Eating disorders are also the second leading cause of premature death among 15- to 24-year-olds in France, according to the country's health insurance agency.
Social media creates a "vicious cycle," Copti said.
"People suffering from eating disorders often have low self-esteem. But by exposing their thinness from having anorexia on social media, they gain followers, views, likes... and this will perpetuate their problems and prolong their denial," she added.
This can especially be the case when the content earns money.
Buigues spoke of a young woman who regularly records herself throwing up live on TikTok and who had "explained that she was paid by the platform and uses that money to buy groceries".
Social media also makes recovering from eating disorders "more difficult, more complicated and take longer", Copti said.
This is partly because young people tend to believe the misleading or fake diet advice that proliferates online.
Copti said consultations with her patients can feel like she is facing a trial.
"I have to constantly justify myself and fight to make them understand that no, it is not possible to have a healthy diet eating only 1,000 calories -- that is half what they need -- or that no, it is not normal to skip meals," she said.
"The patients are completely indoctrinated -- and my 45-minute weekly consultation is no match for spending hours every day on TikTok," she added.
Godart warned about the rise of people posing as "pseudo-coaches", sharing incorrect, "absurd" and potentially illegal nutrition advice.
"These influencers carry far more weight than institutions. We're constantly struggling to get simple messages across about nutrition," she said, pointing out that there are lifelines available for those in need.
Buigues takes it upon herself to regularly report problematic content on Instagram, but said it "serves no purpose".
"The content remains online and the accounts are rarely suspended -- it's very tiring," she said.
The nurse has even advised her patients to delete their social media accounts, particularly TikTok.
"It may seem radical but until young people are better informed, the app is too dangerous," she said.

U.S. star Chen will not defend Olympic figure skating gold in Italy
Reigning Olympic men's figure skating champion Nathan Chen says he will not defend his title at next year's Winter Olympics in Italy figure skating Reigning Winter Olympic men's figure skating champion Nathan Chen of the United States says he will not defend his crown at next year's Games in Italy. Chen told the Los Angeles Times in a story published Saturday that he will continue to pursue a medical career rather return to competition next year for the Milano Cortina Winter Olympics. "I just want to open doors to kind of see what's the best sort of approach for me," Chen told the newspaper. "And frankly, at this point in time in my life, I've already accomplished enough in skating that I'm quite satisfied with my career." Chen, a six-time US champion, won men's world titles in 2018, 2019 and 2021 and helped the US team capture gold in Beijing in 2022 as well as taking his men's crown. The 26-year-old graduated from Yale University last year and is seeking medical school programs. Known as the "Quad King" for his skill at quadruple jumps, Chen holds the combined world record score of 335.30 from the 2019 Grand Prix Final at Turin. Chen is looking to work in cardiology or oncology. "The basis of being a doctor, I think, is to help people," Chen said. "I think that's something that I didn't necessarily feel as an athlete." © 2025 AFP

Global Liver Cancer Cases to Double, Study Says
PARIS (AFP-Jiji) — The number of people with liver cancer will nearly double worldwide by 2050 unless more is done to address preventable causes such as obesity, alcohol consumption and hepatitis, a recent study warned. New cases of liver cancer — the sixth most common form of the disease — will rise to 1.52 million a year from 870,000 if current trends continue, according to data from the Global Cancer Observatory published in the Lancet medical journal. It is also the third deadliest of all cancers, with the study predicting it would take 1.37 million lives by the middle of the century. However three out of five cases of liver cancer could be prevented, the international team of experts said. The risk factors are drinking alcohol, viral hepatitis and a build-up of fat in the liver linked to obesity called MASLD, which was previously known as non-alcoholic fatty liver disease. The viruses that cause hepatitis B and C are expected to remain the leading causes of liver cancer in 2050, according to the study, published on World Hepatitis Day. Vaccination at birth is the best way to prevent hepatitis B, but vaccine coverage remains low in poorer countries including in sub-Saharan Africa, the study said. Unless vaccination rates are increased, hepatitis B is expected to kill 17 million people between 2015 and 2030, it added. It is estimated alcohol consumption will cause more than 21% of all cases of liver cancer by 2050, up more than two percentage points from 2022. Cancer due to obesity-linked fat in livers will rise to 11%, also up more than two percentage points, the researchers calculated. The large-scale study, which reviewed the available evidence on the subject, underscored 'the urgent need for global action' on liver cancer, the authors said. The experts called for more public awareness about the preventable danger of liver cancer, particularly by warning people with obesity or diabetes about fatty-liver disease in the United States, Europe and Asia.

Walking 7,000 steps a day a huge boost to health: research
Step up: Walking even just a little more every day could have big health benefits People who walk 7,000 steps a day have a dramatically lower risk of a broad range of serious health problems, the largest review of the evidence yet said. The most widely promoted target for people tracking their number of steps is 10,000 -- but that figure reportedly originally came from a 1960s marketing campaign for a Japanese pedometer. To find a more scientific target, an international team of researchers sifted through 57 previous studies that covered 160,000 people. The results published in the Lancet Public Health journal found that walking 7,000 steps a day nearly halved people's risk of early death from all causes, compared to 2,000 steps. The study also looked into health problems not previously covered by research into step counts. Walking 7,000 steps a day was linked to people's risk of dementia falling by 38 percent, depression dropping 22 percent and diabetes decreasing 14 percent. It was also associated with lower rates of cancer and falls, though the researchers warned this was based on less evidence. "You don't need to hit 10,000 steps a day to get major health benefits," Paddy Dempsey, a study co-author and medical researcher at Cambridge University, told AFP. "The biggest gains happen before 7,000 steps, and then benefits tend to level off," he said. While people's speeds vary widely, 7,000 steps adds up to roughly an hour of walking throughout the day. Dempsey emphasised that people already managing 10,000 or more steps should keep it up. But he had a message for people who might find 7,000 steps daunting: "don't be discouraged". "If you're only getting 2,000–3,000 steps a day, aim to add an extra 1,000 steps. That's just 10–15 minutes of light walking spread across the day," he said. Andrew Scott, a researcher at the University of Portsmouth not involved in the study, said that "it demonstrates that overall more is always better". "People should not focus too much on the numbers, particularly on days where activity is limited," he added. The World Health Organization recommends at least 150 minutes of moderate to intense physical activity a week. Nearly a third of people worldwide do not reach this target, according to the WHO. © 2025 AFP
