The analysis in The Lancet looks at obesity (肥胖) trend in over 200 countries. In the UK, one in every 10 young people aged 5 to 19, is obese. Obese children are likely to become obese –adults, posting them at risk of serious health problems, say experts. Researchers believe wide availability of cheap, lattening food is one of the main drivers.

Although child obesity rates appear to be stabilizing in many high-income European countries, including the UK, they are accelerating at an alarming rate in many other parts of the world. The largest increase in the number of obese children has been in East Asia. China and India have seen rates “balloon” in recent years. Polynesia and Micronesia have the highest rate of all — around half of the young population in these countries is overweight or obese.

The researchers say that if current world trends continue, “obese” will soon be more common than “underweight”. “We have not become more weak-willed, lazy or greedy. The reality is that the world around us is changing.”

Dr Fiona Bull from the World Health Organization suggested tough measures to prevent “calorie-rich, nutrient-poor food” and entourage more physical activity. “But so far, just over 20 countries around the world have introduced a tax on sugary drinks,” she said.

Dr Alison Tedstone, chief nutritionist (营养学家) at Public Health England, said, “Our sugar reduction programme and the government’s sugar tax are world-leading, but this is just the beginning of a long journey to meet the challenge of a generation. The evidence is clear that just telling people what to do won’t work. While education and information are important, deeper actions are needed to help us lower calorie consumption and achieve healthier diets.”
