问答题 The announcement comes after experts estimated that most of the population in Britain would be obese by 2050 unless urgent action is taken and the related rise in ill health would cost the National Health Service 50 billion pounds a year. According to ministers, giving people incentives to fight the flab will help avoid larger costs associated with treating cancer, heart disease and diabetes caused by obesity. The government said that it wants to make Britain the first major nation to quash the rising tide of obesity. And the milestone strategy-Healthy Weight, Healthy Lives-is their solution to the problem. The strategy will feature a series of projects run through a Well@work scheme led by British Heart Foundation, which will offer rewards to workers who lose weight.
