Implement the fattening plan. 1. A balanced diet can increase calories by using high-fat and high-sugar foods such as cream or other edible oil, jam and sugar. Although weight gain is relatively rapid, long-term or excessive consumption will destroy appetite, and may bring chronic diseases and endanger health. Take a balanced diet, gradually increase the amount of food, avoid compulsive supply and destroy appetite. 2. Develop good eating habits, regularly quantify, eat a small amount and eat slowly. 3. Change the dining procedure. Eat foods with high concentration and high nutritional density before eating other foods. 4. Choose moderately cooked food. Choose foods with moderate cooking, such as steaming, stewing, marinating, frying and boiling. Avoid food hardening and indigestion due to frying, frying and baking. 5. Keep a happy mood, arrange the dining environment and concentrate on eating. Tension and anxiety not only affect appetite, but also the digestive and absorption function of gastrointestinal tract is not good, and the improvement of metabolic rate consumes relatively more calories.
