Hello, aerobic exercise on an empty stomach refers to low to moderate intensity aerobic exercise on an empty stomach in the morning or within 2 hours after meals, such as jogging, brisk walking and cycling. This kind of exercise is considered to promote fat burning and achieve the effect of reducing fat and weight.

Studies have shown that aerobic exercise on an empty stomach can really promote fat burning, but its lipid-lowering effect is not faster than aerobic exercise at other times. In fact, some studies even found that aerobic exercise on an empty stomach may lead to muscle decomposition and affect health.

In addition, fasting exercise may also affect sports performance. Because in the fasting state, the body's energy reserves are less, and it is easy to feel uncomfortable symptoms such as fatigue and dizziness, which affects the duration and intensity of exercise. Therefore, for beginners or people in poor health, aerobic exercise on an empty stomach is not recommended.

In short, aerobic exercise on an empty stomach is not a "panacea" for reducing fat and weight. When choosing exercise time and mode, we should choose according to our physical condition and exercise purpose, exercise moderately and eat a balanced diet to achieve the effect of healthy fat reduction.
