It is necessary to make up for the nutritional liabilities that may be caused by eating less breakfast, exercising more in the morning and consuming more, and to reserve energy for afternoon activities, so the quality of diet should be high and the quantity should be relatively sufficient. Lunch should have a larger share of staple food and more kinds of non-staple food. It is best to eat fruit once in the afternoon. Eat less dinner because there is little activity in the evening.
