First, do exercise on an empty stomach?
Generally not recommended, but it depends.
Your body is yours, and you know best. Some people don't pursue high-intensity exercise. Exercise on an empty stomach is time-saving and convenient, easy to arrange in daily life, and moderate and low-intensity exercise is not too dangerous. When you doubt whether a certain method is suitable for you, you might as well try it and make a record to compare which method is more suitable for you. Of course, the premise is that these methods are relatively safe, so people with blood sugar regulation and cardiovascular and cerebrovascular problems should try fasting exercise.
Second, what is the harm of doing exercise on an empty stomach?
1, easy to cause gastrointestinal diseases, gastrointestinal diseases are not only related to daily overeating, but also related to exercise without eating anything after getting up early. Because most people's lives are tense, they start eating lunch immediately after exercising in the morning. In fact, eating immediately after fasting exercise will reduce gastrointestinal metabolic function, and it is more likely to suffer from gastrointestinal diseases in the long run.
2, it will lead to dizziness, and some people are prone to dizziness in morning exercise. In fact, the main reason for this symptom is because of fasting exercise in the morning. Because after getting up in the morning, the nutrients in the human body are almost exhausted, and the blood sugar concentration in the blood will be greatly reduced. If you exercise on an empty stomach, you will not only be unable to stay healthy, but also feel dizzy and vomit in severe cases.
3, easy to lead to arrhythmia According to expert research, if you exercise without eating any food, especially running, it will not only increase the burden on the liver, but also lead to arrhythmia. Because the human body needs a lot of energy when exercising, and the main source of human energy is carbohydrates in food. If it is on an empty stomach, the energy consumed by the human body mainly comes from fat.
