At the same time, the diet should also be calorie-controlled, and three meals a day should be eaten on time, and each meal should be 7 minutes full. The overall diet should be light and less oily, eat more vegetables, replace flour and rice with coarse grains, and ensure sufficient fruit and high-protein food every day. Meat is mainly low-fat lean meat such as chicken and fish, and high-calorie foods such as fat meat, alcohol, cakes and desserts, carbonated drinks, fried foods and various snacks should be eaten as little as possible. Foods with low calorie and strong satiety, such as fruits, vegetables or dairy products, can be added as meals between meals to control dietary calories.
