A top health expert has urged Chinese authorities to better implement policies aimed at averting a national obesity crisis.

The call comes after the latest report on the general health of Beijing residents discovered that more people are at risk of diseases brought on by being overweight.

Wang Linhong, deputy director of the National Center for Chronic and Non-Communicable Disease Control and Prevention, said sedentary lifestyles and poor diets containing large amounts of sugar and fat have made obesity an increasingly serious problem in China.
