It is suggested to encourage children to exercise more, sit less and play less computers, games and mobile phones. Drink a glass of water before each meal. Eat in the order of the main meat in the soup. This can effectively reduce calorie intake. I wouldn't be so hungry. Eat early and eat less at dinner, so that the body can digest the food almost before going to bed. Don't deliberately lose weight, so as not to affect the normal development of children. I hope I can help you.
