When we do aerobic training to lose weight in the morning, many people say that it is best to do some aerobic training on an empty stomach, so that the weight loss effect will be better. Some people think that doing aerobic training on an empty stomach is not as good as others say, and it is likely to hurt themselves. So do you think aerobic training on an empty stomach is more beneficial to lose weight? Let's take a look at fitness knowledge!

First, what is fasting aerobic exercise?

The so-called aerobic training on an empty stomach refers to aerobic training such as jogging, brisk walking and swimming on an empty stomach without eating or drinking boiled water after getting up in the morning. The scientific principle of fasting aerobic training: it can accelerate the decomposition of lipids. Fat decomposition promotes fat oxidation and accelerates fat loss. People who exercise on an empty stomach in the morning burn 20% more fat than when they eat. Because on an empty stomach, the body has no extra carbohydrates as energy supply, so it will burn more fat to provide aerobic training for the body.

Second, is it better to lose weight by aerobic exercise on an empty stomach?

Aerobic exercise on an empty stomach is not good for losing weight. In the early days, fasting exercise does increase the proportion of fat burning, but these studies are often only short-term effects of exercise, not long-term analysis. Although fasting can burn more fat during exercise, interestingly, the body has a "smart" compensation mechanism, which in turn reduces the use of fat at rest. So if you think about it all day, it doesn't really make any difference. Only exercise after breakfast can improve the fever reaction after exercise, which is usually called heat consumption after exercise, so it increases the total heat consumption of a day in disguise.

Third, what are the hazards?

According to expert research, if you exercise without eating any food, especially running, it will not only increase the burden on the liver, but also lead to arrhythmia. Because the human body needs a lot of energy when exercising, and the main source of human energy is carbohydrates in food. If it is on an empty stomach, the energy consumed by the human body mainly comes from fat.
