All parents want their children to be fit and healthy, but it can be hard to persuade them to eat less junk food and take more exercise. However, research shows that, in the UK, childhood obesity has tripled since 1995.
A government report predicts that, unless we tackle the problem now, half of primary school boys and 20% of primary school girls could be obese by 2050, and our children could be the first to have a shorter life expectancy than their parents, as a result of obesity-related illnesses like heart disease and diabetes.
