According to the traditional living habits, it is generally better to have three meals a day, and the interval between meals should be 4 6 hours. Eat more for lunch, less for dinner and less for breakfast. After a night's sleep, the function of digestive system has not recovered to the best state, so fine food with small size, complete nutrition and high calorie should be used for breakfast; Before and after lunch are working hours, to make up for the calories consumed in the morning and prepare for the work in the afternoon, so it is necessary to take up more calories, so it is advisable to choose foods rich in protein and fat; After dinner, it is a rest time, which consumes less energy. You should eat some digestible foods, such as sugar and vegetables. Because you sleep at night and eat too much nutrition, it will be converted into fat and stored, and you will get fat over time. At the same time, overeating at dinner will increase the burden on the stomach and affect sleep.
Modern medicine believes that a regular work and rest system can establish various conditioned reflexes in the brain nerve center, and make them constantly consolidate and form stable and good living habits. This series of conditioned reflex can regularly promote the healthy development of human physiological activities.
