Over the past 20 years, the number of children who are overweight has increased by more than 50%.About 25% to 30% of school-age children in the United States are overweight or obese (肥胖的), which puts them at a high risk for heart disease and other health problems.
According to the experts, poor eating habits and inactivity are the root causes of childhood obesity. In addition, the high level of fat calories in the average United States diet combined with the inactive lifestyle of many children is contributing to (促成) the rapid increase in childhood obesity.
If a child is more than 40% overweight, a scientific weight loss program may be suggested to change the child's eating behaviors. During the course of the program, the emphasis should be on developing a healthier lifestyle for the long term, not just on losing weight now. Children are developing physically and mentally, and they need adequate nutrition (足够的营养) as they grow. Combining a healthy diet with exercise is the best way to achieve healthy level of body fat.

Make good nutrition and exercise a family affair by planning lower fat meals, nutritious snacks and family activities.”
