Fasting exercise is closely related to comfort first. At the same time, fasting exercise may have an advantage in losing weight. Because, after a night without energy intake, the glycogen storage in the body becomes low.

However, the body will continue to consume glycogen during exercise. In order to make up for this glycogen deficiency, the body will automatically consume fat to maintain normal blood sugar levels. In this way, in terms of energy consumption, fasting will burn more fat.

Disadvantages: Exercise on an empty stomach must be cautious. Because, for the body, if the way is improper, fasting exercise will become redundant efforts, which may bring some harm: excessive lack of glycogen will lead to hypoglycemia.

Therefore, exercise on an empty stomach should pay attention to the risk of nausea and fainting. Be sure to take necessary precautions. The first thing is to obey the body: if the exercise is too difficult and intense for me, stop at once.

Take some food with you so that you can eat it when you need it for training. Pay special attention to replenish water in time, and don't neglect the dinner after exercise, which is very important to provide the energy needed by the body.

Finally, exercise on an empty stomach should not exceed two or three times a week, and each exercise should not exceed one hour. Otherwise, not only the consumption of the body is not obvious, but it may even lead to risks.
