After eating breakfast an hour to an hour and a half can be some low intensity exercise, two hours to be consumed by the breakfast almost can be normal intensity of exercise.
Do not engage in strenuous exercise within half an hour after the meal, it will very much affect the digestive function and thus affect the health of the body.
After the meal the body's energy is mainly concentrated in the digestion, shortly after the meal on the intensity of the exercise is likely to lead to gastroptosis, is not conducive to health. The first thing you can do is to walk slowly to help your digestive system break down and absorb the food.
If you start exercising vigorously while your food is being digested, your body's priorities change and blood flows to your muscles; this also happens when your body is under stress, which triggers a chain reaction that prepares your body for intense exercise (known as the "fight-or-flight response").
The worst-case scenario is usually swimming shortly after a meal, because not only does the blood have to supply the muscles and the digestive system at the same time, but it also has to keep the body in the water at a certain temperature, so the most conservative consequence is that the muscles don't have enough blood supply to cramp up, and you can't swim again for a while.
The length of the interval between meals and pre-exercise depends largely on the meal and its dosage, while other determining factors include age, physical condition and intensity of exercise. Assuming that you are a middle-aged person, if you eat a large amount of food before exercise, and most of it contains a high amount of protein and fat-based food, the interval should be more than two hours; if you eat a smaller amount of food and mainly carbohydrates, the interval can be shortened to 30 minutes to one hour.
