Is it good to run on an empty stomach?
In general, whether running on an empty stomach is beneficial or not depends on individual physical conditions and exercise goals. It may be suitable for those aiming to lose weight or improve fat-burning efficiency, but it is not recommended for individuals with weak constitutions or chronic diseases. The detailed analysis is as follows:
For people who want to lose weight or enhance fat-burning efficiency, running on an empty stomach might be a good option. When fasting, glycogen stores in the body are low, so during exercise the body may rely more on fat as an energy source, which can help promote fat burning and weight loss.
However, individuals with weak physical conditions or chronic health issues should avoid running on an empty stomach. Due to insufficient energy supply, they may feel more fatigued and weak. Running in this state increases the risk of hypoglycemia, potentially causing symptoms such as dizziness and fatigue. Additionally, people with sensitive gastrointestinal systems may experience stomach discomfort when exercising while fasting.
It is recommended to choose an appropriate form of exercise, engage in moderate physical activity, and gradually improve overall fitness.
