For some people, eating supper is a habit. If you often work overtime, midnight snack is a physiological need to replenish energy. Don't believe the lie that eating at night will make you fat. Starving and sleeping at night is not necessarily a good idea. However, there is little exercise at night, so be careful when choosing snacks. Eating too many calories will make you fat. It is best to give priority to oats, low-fat milk or fresh fruits and vegetables for supper, so that you can be full and slim.
