Pay attention to consumption is greater than intake. Increase the amount of exercise according to your physique and reduce the time spent sitting and playing computer games. 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 your body can digest food almost before going to bed. Don't deliberately lose weight, so as not to affect your physical development.
