Control diet, that is, light diet, eat more fruits and vegetables, avoid alcohol and tobacco, avoid fried sweets, have seven or eight full breakfasts and six full dinners, and eat less stuffed foods, such as jiaozi, vegetable cakes and steamed stuffed buns. Exercise more, especially after dinner, but don't do strenuous exercise such as long-distance running and jumping. Walking is the best exercise to lose weight. Keep a happy mood, relax and get enough sleep, but don't stay in bed too much. Keep the stool unobstructed.
