How to eat scientifically when exercising

　　Many fitness friends will experience some kind of physical discomfort during fitness. In fact, a large part of the reason is caused by our failure to pay attention to dietary hygiene. For example, stomachache due to running, hypoglycemia due to exercise, etc. These situations can be avoided if we pay attention to the following meals before and after fitness and ensure that the meals are reasonable. Below we will introduce to you how to ensure dietary hygiene during your fitness process.

    1. Not on an empty stomach exercise：

　　The blood sugar in the human body decreases during fasting, which can cause dizziness, weakness in the limbs and even fainting. Additionally, exercising on an empty stomach can cause feelings of hunger, which may occur stomach ache , it will also inhibit the secretion of digestive juices, reduce digestive function, and easily cause accidents.

　　2. Don’t do a lot of exercise after meals:

　　The activity of digestive organs after meals requires a large amount of blood supply. This is due to participation in fitness exercises. Since a large amount of blood flows to the muscles of the limbs, the blood flow in the gastrointestinal tract is reduced, thus affecting the digestion and absorption of food. In addition, when the gastrointestinal tract is compressed by equipment or its own load, peristalsis is restricted, which can easily cause mechanical dysfunction, gastric cramps, abdominal pain, sweating, or vomiting. Therefore, exercise usually starts 1.5 to 2 hours after a meal.
