Fasting exercise, fat loss really faster What is the effect of fasting exercise on the body？

Exercise on an empty stomach, lose fat faster, I believe you should have heard this statement.

I believe that many people who are just in contact with exercise to lose weight have also believed in this statement, and have practiced it. Perhaps only those who have run on an empty stomach can understand what kind of feeling. From the first step, they feel it is difficult to run until they really can't move. After a period of practice, the body did make some progress. The discomfort of running on an empty stomach was not as strong as at first, but there was no significant change in weight or body fat content.
Practice tells us that the faster you lose fat on an empty stomach may just be a long-held myth, or, if it does, the faster you lose it, the faster you lose it on a scale.
In 2020, fasting has become more and more popular, and many people are trying intermittent fasting or shortening the time window of eating. In this case, fasting exercise has become a common situation. How does fasting exercise affect the body?

The core problem of fasting exercise:

How does your body react to exercise on an empty stomach and after a meal?
Does fasting exercise reduce fat faster?
Does fasting exercise affect performance?
Does fasting exercise burn more muscle?
Finally, should we exercise on an empty stomach?

01, fasting and postprandial exercise, how will the body react?

The main difference between fasting and postprandial exercise is the energy supply during exercise.

Exercise on an empty stomach

On an empty stomach (usually for a night without food), the body has low carbohydrate stores, mainly lower levels of glycogen in the liver, and lower levels of available glucose in the blood. Exercise puts the body in a state of energy expenditure. Where does energy come from?
While the body struggles to get glucose from other sources, such as burning glycogen in muscles or converting it to glucose with protein and fat, it burns stored fat. So your body burns more fat when you exercise on an empty stomach.
However, at the same time, due to the decrease of liver glycogen reserve during fasting, and the main function of liver glycogen is to maintain the stability of blood glucose level, if there are problems in blood glucose regulation itself, such as diabetic patients, exercise at this time is more prone to hypoglycemia and other symptoms.

Postprandial exercise:

After a meal, the body is rich in glucose, which can be used directly to fuel exercise, so you don't need to use as much fat reserves. Specific carbohydrate and fat energy supply ratio is still related to the intensity and time of exercise, the higher the intensity of exercise, the higher the proportion of carbohydrate consumption.
