According to your physical activity, calculate the total calories of a day. While ensuring the intake of carbohydrate, protein, fat and three nutrients, we should appropriately increase foods rich in dietary fiber, such as celery, bean sprouts and fresh fruits and vegetables. Drink more water after meals and pay attention to exercise. Try not to eat after 8 pm. Avoid frying foods high in fat and sugar. In short, three meals are not excessive, and exercise reasonably after meals. Perseverance will achieve the effect of losing weight.
