Hello, reasonable diet and exercise. First of all, you should arrange your three meals a day reasonably, eat more vegetables and fruits, eat well in the morning, eat less at noon, drink a cup of warm water or honey water in the morning, and eat meat at noon or morning. As for sports, you can go out running, skipping rope, doing sit-ups, dancing and so on in the morning and evening. It won't have a good effect in the short term, but stick to it for a long time.
