In order to achieve the purpose of rapid weight loss, some people will choose to do aerobic exercise on an empty stomach, although fasting exercise can lose weight, but it may bring certain harm to the body for a long time.

Can you lose weight by exercising on an empty stomach?

First of all, let's talk about fasting exercise, which mainly refers to aerobic exercise in an fasting state. The digestion process of food in the human body is mainly divided into fasting state and eating state, fasting state mainly refers to the stage after people digest and absorb food, and the eating state is the stage when people are digesting and absorbing food. When you are in the eating stage, your blood sugar will rise, and a large amount of insulin will be secreted, which is actually easy to accumulate fat. When fasting, the blood sugar level will slowly decrease, and the insulin will return to its normal state, and the fat will be easily broken down. Aerobic exercise when people are in a fasting state can speed up the breakdown of fat, especially in the morning, which can burn 20% of the fat in the body. When you do aerobic exercise on an empty stomach, your body doesn't have more carbohydrates to provide energy, which burns fat.

What are the dangers of fasting exercise?

1. Cause irregular heartbeat

If you exercise without eating any food, it will increase the burden on the liver, which will cause people to have irregular heartbeats. Because we need to burn more calories when exercising, our body's energy mainly comes from carbohydrates stored in the body, and when fasting, the body consumes a lot of fat to provide energy.

2. Dizziness

Some people may experience dizziness and dizziness when exercising on an empty stomach, which generally occurs during morning exercise. Because there are no nutrients in the body after waking up in the morning, the blood sugar concentration will decrease, and exercising on an empty stomach will not only not improve the body, but also cause dizziness and even vomiting.

3. Gastrointestinal diseases

Nowadays, people's pace of life is relatively fast, and some people will eat immediately after exercising on an empty stomach in the morning, which will disturb the metabolism of the gastrointestinal tract and cause gastrointestinal diseases for a long time.
