Because exercise at this time can best mobilize the metabolic function of the human body, which is conducive to decomposing more fat, secreting more growth hormone, promoting muscle production and delaying aging. Therefore, if there is no problem of blood sugar control and hyperlipidemia, exercise before meals is no problem. Going to the gym immediately after work, or running and playing ball, going home after an hour of exercise, and having dinner after half an hour's rest are all good arrangements. However, in order to avoid blood concentration and dehydration, you should drink some water before and after exercise.

However, if you have three high hypoglycemia, you are hungry, your legs are weak, you are flustered, you are depressed, and your stomach is upset. It is best not to do high-intensity exercise. People with stomach problems should also pay attention, because when the exercise intensity is slightly higher, the blood supply to the stomach will decrease and they will feel more uncomfortable.

However, this does not mean that these people can't exercise before meals, just need some food to prevent all kinds of discomfort and stabilize blood sugar supply. You can eat an apple, drink a glass of milk, yogurt, or drink a small bowl of porridge before exercise. In this way, the low blood sugar level can be raised, and the physical quality can also be uplifted. At the same time, because these foods also supply water, the problem of blood concentration during exercise can also be avoided.
