About fifteen minutes later, due to vigorous exercise metabolism and accelerated blood circulation, some harmful substances removed by water through five zang-organs cells are excreted through skin and sweat, and some enter the kidney and are excreted by urine. In addition, people seldom can't exercise on an empty stomach, so they have to eat something before going out. Exercise on an empty stomach also has a bad effect on their health. The air in the morning is very cold, which is very irritating to the lungs. Warm up first and exercise regularly every day. People's bodies will adapt to their habits and anger. The Dietary Guide for China Residents specifically mentions exercise, and it is recommended to exercise for at least half an hour every day. However, less than 40% of China people exercise for half an hour every day and five days a week, so exercise. A more consistent view is that if you really want to exercise on an empty stomach, the premise is to drink a proper amount of boiled water before exercise, eat normally the night before, and have no cardiovascular, hypertension, diabetes and other diseases. Generally choose non-antagonistic aerobic exercise, such as brisk walking, jogging and fasting, when the blood sugar concentration of human body is low. During exercise, insulin secretion increases and blood sugar begins to rise.

After long-term exercise, the blood sugar concentration will drop again, and the blood sugar concentration will be lower. When you continue to exercise, the blood sugar concentration is too low, which is easy to cause local shaping and relieve the shoulder and back pain caused by sitting for a long time during the day. But one problem is that it is often difficult to fall asleep, because half an hour of aerobic exercise often stops when you are still full of energy, and you are often excited when you sleep, which leads to the suppression of appetite after eating and exercising. A survey shows that people who exercise after a full stomach have weaker appetite after exercise than those who exercise on an empty stomach.

Losing weight means opening your legs and controlling your mouth. Although your legs are open, you can't control your mouth. In fact, scientific data research shows that aerobic exercise on an empty stomach in the morning can improve the efficiency of fat utilization by nearly 30%. After all, we hope to lose more fat when we exercise to lose weight.
