Doing aerobic exercise on an empty stomach will have a certain weight loss effect. However, it is recommended not to exercise on an empty stomach, because on an empty stomach, although you can burn body fat better, your muscles are also lost. At the same time, due to the low energy of the human body, it is prone to dizziness, which is still very harmful to the human body. For people with high physical fitness, if you want to choose fasting exercise, it is recommended to choose intermittent high-intensity exercise. High-intensity exercise can quickly increase the heart rate and accelerate the burning of body fat. At the same time, shortening the exercise time as much as possible can effectively prevent excessive muscle loss. It also helps the body to recover quickly and reduces the influence of fasting exercise.
