Exercise plus dieting not only affects the stomach, but also needs food to replenish energy after exercise. Excessive dieting can easily cause hypoglycemia and dizziness after a long time. Dieting should be done at dinner, because there is less exercise after dinner and fat is long at this time. You can adjust your eating habits, eat dry food for breakfast and lunch, and give priority to liquid food for dinner, that is, eat enough water. If you eat like this, your stomach will be relieved at night and your sleep quality will be good. You just have to get used to it.
