If you exercise during the day, eat something to restore energy at night, such as sugar-based foods, such as porridge and steamed bread, which can quickly replenish the energy consumed by the human body without consuming a lot of nutrients to replenish energy. But don't eat anything particularly greasy. First, eating too greasy things before going to bed is not good for your health, it is not easy to digest, and it will increase the burden on your stomach. Secondly, it is too difficult to convert the fat contained in greasy food into sugar that can be directly consumed, and more of it is still accumulated in the body, which may make people fatter and fatter, and others seem to be getting fatter and fatter.
If it is convenient for you to eat at night, you can eat some foods containing more plant fiber, such as potatoes and celery. The fiber in this kind of food is difficult to digest and has no advantage over other foods in supplementing energy. But plant fiber can clean the stomach, because it is difficult to digest, so it can take away excess intestinal oil and inevitable food residues from the stomach. This will make your appetite better the next day, and you will have enough energy intake when you meet the next day's exercise.
