Why can't you exercise on an empty stomach? The harm of exercising on an empty stomach

For modern young people, exercise is a very good thing, but we should also exercise at different times and in different situations. However, it is better not to exercise on an empty stomach, because it is harmful to our body. So I hope that those who like exercise should remember: it is best not to exercise on an empty stomach.

Why can't you exercise on an empty stomach?

Adhering to moderate physical exercise can consume energy, increase the number of insulin receptors in muscle cells, lower blood sugar, and improve the effectiveness of insulin. Exercise can also promote blood circulation, reduce blood lipids and blood viscosity, and help control complications; patients can also enhance heart and respiratory functions and strengthen bone toughness during exercise, making diabetic patients happy, muscular, and physically fit. However, you should pay attention to the following when exercising:

1. Choose the right time

Many people like to exercise in the early morning, but it is not suitable for diabetic patients. Because when the patient is fasting, the blood sugar level is the lowest. Exercise at this time can easily cause hypoglycemia. Therefore, diabetic patients should arrange exercise time one hour after a meal. To prevent hypoglycemia, you can carry some biscuits, candies, chocolates or sugary drinks and water with you.

2. Exercise should not be too intense

You should do moderate-intensity, slow-paced aerobic exercise, such as walking, jogging, doing exercises, practicing Tai Chi, practicing Tai Chi sword, dancing, and dancing Yangko.

3. Prevent foot injuries

When exercising, you need to wear elastic sports shoes with slightly thick soles and neither soft nor hard uppers, as well as cotton socks with good water absorption. You should always check whether there are foreign objects in your shoes and clean them in time to prevent foot injuries.

4. It is best to test your blood sugar before exercise

You cannot exercise when your blood sugar is too high (greater than 16 mmol/L) or too low (less than 6 mmol/L). People with cardiovascular disease or kidney disease should limit their activity.

5. Check your heart rate at any time during exercise

The best heart rate during exercise should be 170-age. Avoid exercising blindly without any consideration.

The dangers of exercising on an empty stomach

There are some things to pay attention to when exercising. Is it better to exercise on an empty stomach or on a full stomach? There is some controversy on this issue. Experts will introduce to you the harms of exercising on an empty stomach.

People know that it is not good to exercise on a full stomach, but they do not agree with exercising on an empty stomach. They think that the stomach and intestines do not need much blood when exercising on an empty stomach, and the stomach and intestines will not conflict with the limbs for blood. In fact, this is a wrong understanding. Exercising on an empty stomach is more dangerous.

The main source of energy for the human body is carbohydrates (sugar) in the diet. After a night's rest, the energy in the body is almost consumed, and the blood sugar concentration in the body is low. At this time, if we exercise without eating anything, we will inevitably consume a lot of energy, and the blood sugar concentration will be even lower. Blood sugar is the direct energy substance for the brain. If the blood sugar concentration is too low, the brain will feel tired due to lack of power, and people will feel dizzy and weak. Some people will also turn pale and sweat. If it continues, they will become unconscious or even comatose.

Another disadvantage of exercising on an empty stomach is that when a person is on an empty stomach, the main source of energy is converted from body fat. At this time, the free fatty acids in the blood will increase significantly. Fatty acids are the energy source for muscle activity such as the myocardium, but when the amount is too much, it can become a poison to the myocardium, causing various arrhythmias and even sudden death.

Therefore, we must not exercise on an empty stomach. If you exercise in the morning, you can drink some honey water before exercising to avoid danger.
