Young people are so worried about obesity these days that they often go on strict diets which put their health at risk, a top psychologist has warned.
Children who go on crash diets are 12 times more likely to develop an eating disorder in later life, a recent study in Australia showed.

"Starting to diet in teenage years can be very dangerous," said Professor Marion Hetherington.
"Dieting is a struggle, it involves us trying to beat our biological desires, but it can lead to yo-yo dieting."
Teenagers should be taught about staying healthy, but they must be careful not to go overboard and risk developing an eating disorder.
