2. Exercise: Encourage children to take proper physical exercise, such as swimming, running, cycling and other aerobic exercises, to help consume excess calories and enhance physical fitness.

3. Establish healthy living habits: keep regular work and rest time, get enough sleep time, and avoid bad habits such as excessive use of electronic products.

4. Seek professional help: If your child has a serious weight problem, you can consult a doctor or dietitian and make a personalized weight loss plan.

5. Parents' guidance and support: Parents should give their children enough care and support, encourage them to face the weight problem positively, and don't put too much pressure on them or criticize them.
