Is it good to run on an empty stomach in the morning?

In general, whether it is beneficial to run on an empty stomach in the morning needs to be analyzed according to individual circumstances. If a person is in good health, running on an empty stomach in the morning can be beneficial. However, for individuals with digestive system diseases such as gastritis or peptic ulcer, it is not recommended to run on an empty stomach in the morning. Detailed analysis is as follows:

When in good health, the body's glycogen reserves are relatively low, and running can effectively mobilize fat for energy supply, helping to improve fat-burning efficiency and promote weight management. In addition, fasting running can help enhance the body's metabolic rate, promote blood circulation, and improve cardiopulmonary function. Therefore, if physical conditions permit, running on an empty stomach in the morning is acceptable.

For individuals with digestive system diseases such as gastritis or peptic ulcer, running on an empty stomach in the morning may have adverse effects. During fasting running, the body requires more energy to support physical activity, which may lead to increased gastric acid secretion, thereby aggravating damage to the gastric mucosa. For those who already have inflammation or ulcers in the gastric mucosa, this stimulation may trigger discomfort symptoms such as stomach pain and nausea, and may even worsen the condition. Therefore, these individuals should avoid running on an empty stomach in the morning to prevent unnecessary harm to their health.

In daily life, it is important to maintain adequate hydration, avoid excessive fatigue, and gradually increase exercise intensity in order to promote overall health and improve physical fitness.
