If a child is obese, parents should control their child’s diet and increase their physical activity, such as swimming or jogging. In terms of diet, encourage the child to eat more cucumbers, carrots, spinach, etc., and strictly prohibit high-calorie foods like cakes and chestnuts. Also, help correct bad habits like not being active after eating or picky eating. If the child’s condition is severe during treatment for obesity, it is essential to take the child to a regular hospital for treatment.
