Being too fat is bad for children' s health.According to the World Health Organization （WHO），overweight children are more likely to develop diseases like diabetes（糖尿病） at a younger age.This can lead to a higher chance of earlier death.

On Oct 23rd，the NHC，together with five other national departments，worked out a plan.The plan aims to reduce the growth of fatness among children aged 0﹣18 years by 70 percent from 2020 to 2030，Xinhua reported.

Kids are putting on weight because of changes in their diet and lifestyle，according to experts.Too much schoolwork and greater use of electronic devices（ 电子产品） could also be a cause.

According to the plan，teachers should not allow their classes to run too late or too early.They should make sure that students have breaks and enough physical（躯体上的） activity.School students should have at least three hours of active physical activity each week.

Parents should reduce their children's use of electronic devices and stop their children from eating foods that are high in sugar，fat and salt.
