Unable to reason
If you exercise just after a meal, the food in your stomach will vibrate up and down, left and right with the exercise, causing mechanical stimulation to your stomach, causing stomach cramps and vomiting, so you can't exercise immediately after a meal.
Correct approach
The correct way is to have a rest after meals, and the rest time varies according to the specific situation. It is appropriate to rest for enough time before running or doing other physical exercises. Generally, a lot of water will be consumed during exercise, and various inorganic salts will be taken away with the evaporation of sweat, so water should be replenished in time after exercise.
According to the intensity of exercise, you can take a walk and take a walk for half an hour to one hour after meals. Moderate exercise such as jogging, weight-loss exercises and cycling can be carried out one to two hours after meals. High-intensity sports such as long-distance running, skipping rope, playing football and basketball should be carried out two to three hours after meals.
According to the appetite, if you eat a lot before exercise, and the food you eat is mainly protein and fat, which is not easy to digest, then it is best to exercise for more than two hours after meals. If the amount of food is small and the food is mainly carbohydrates, vegetables and fruits, the interval between exercise and eating can be relatively shortened according to the intensity of exercise.
