I recommend oatmeal milk. Oatmeal not only contains enough carbohydrates, rich soluble fiber and B vitamins, but also can increase people's satiety, and will not produce a lot of energy, so as to avoid the phenomenon that your body secretly gains weight after sleeping. Milk contains a lot of trace elements such as protein, calcium and magnesium, so the combination of them is not only a combination of "dry" and "wet", but also a good partner of nutrition. Not only healthy and full, but also with milk, nuts and so on, which is more nutritious and delicious. When choosing, you should choose oatmeal with low processing degree and no added sugar instead of oatmeal with various food additives. Saccharin is high in calories and is not an essential nutrient for human body. You can choose instant oatmeal when eating at night, so you can eat it as long as you brew it with hot milk for a few minutes.
