Startling new research shows that a weekly injection can help obese people shift a fortune of weight – by turning off their unusually ferocious appetite. It’s led experts to be even more convinced of the idea that obesity is not a result of greed or lack of willpower – but a biological fault that causes extreme hunger. Daily Mail columnist Sarah Vine tells of how the injection, called semaglutide, changed her life by curbing her overwhelming desire to eat junk. Meanwhile, obesity campaigner Sarah Le Brocq argues that treating larger Britons as patients with a sickness is the only way to tackle lifestyle-related disease. Yet, Dr Asher Larmie, a GP and fat activist, passionately disagrees. Shockingly, Dr Larmie even doubts the evidence linking obesity to diseases like diabetes.
