First of all, we should pay attention to the diet, not to say that we are not hungry, but to balance the diet, eat as little greasy things as possible, and not eat fat, skin and viscera, which are high in cholesterol and fat. Lean meat can be eaten in moderation, not in excess. Eat more yogurt, vegetables and fruits. Then exercise at ordinary times, don't eat too much dinner every day, just eat until you are not hungry, and go downstairs for a walk and run after 20 minutes.
