Introduction

Running on an empty stomach in the morning is not good for the body. Exercising while fasting increases the level of free fatty acids in the bloodstream. Excessively high levels of free fatty acids can produce toxins that damage the heart muscle, potentially leading to arrhythmia or even sudden death. Additionally, fasting exercise may cause hypoglycemia. Therefore, intense or strenuous physical activity should be avoided on an empty stomach in the morning.

In general, whether running on an empty stomach in the morning is beneficial depends on an individual's physical condition and health goals. If any discomfort occurs, it is recommended to seek medical advice promptly. The details are as follows:

1. Beneficial

For individuals who are not suffering from hypoglycemia, as well as pregnant women, children, elderly people, or those at risk of cardiovascular disease—especially those aiming for fat loss—running on an empty stomach in the morning may be beneficial. At this time, glycogen stores in the body are relatively low, causing the body to rely more on fat as an energy source, which can enhance fat-burning efficiency and support weight management.

2. Not Beneficial

For individuals with hypoglycemia, pregnant women, children, elderly individuals, and those at risk of cardiovascular disease, running on an empty stomach in the morning may be harmful. Hypoglycemic individuals may experience dizziness, fatigue, or even fainting due to insufficient immediate energy supply. Pregnant women and children may have their growth and developmental needs negatively affected by fasting exercise. For older adults and those with cardiovascular risks, running while fasting may increase cardiac workload and trigger adverse reactions.

To avoid unnecessary physical harm, it is advisable to consult a healthcare professional. Regardless of when you exercise, adjust the intensity and duration according to your physical condition to prevent overexertion. It is also important to properly hydrate and replenish nutrients before and after exercise to maintain bodily balance and optimal function.
