How to treat childhood obesity and laziness effectively

Patient's question:
My son is 2 years old. Recently, I feel that he has gained a lot of weight, and he's been eating more lately. He's also particularly lazy. What's the best way to treat childhood obesity and lethargy?
Doctor's answer:
If your child has obesity, parents should improve the situation through exercise and dietary changes. Encourage your child to engage in activities suitable for his age, such as swimming or jogging. Also, make sure he eats plenty of vegetables, like tomatoes and cucumbers, and avoid high-calorie, high-fat foods, such as burgers, fries, and cookies. Additionally, it's essential to change your child's habit of disliking exercise, as it can easily lead to fat accumulation. During the treatment for childhood obesity, if your child's symptoms are severe, it's crucial to seek medical treatment promptly. Don't blindly trust certain medications.
