"Walking a hundred steps after a meal, you can live ninety-nine", the simplest truth is that exercise after meals helps digestion and absorption, from a medical point of view, it can promote gastrointestinal peristalsis, and from a deeper level, it can speed up the body's utilization of nutrients such as blood sugar and fat, and avoid the occurrence of hyperglycemia and hyperlipidemia caused by excess, especially for people with diabetes.
But how to exercise to really play its role is particular, for example, how long after a meal to exercise without injuring the body is a time requirement. So, how long after a meal is the right time to exercise?
First of all, from the perspective of the digestion and absorption process of food by the gastrointestinal tract, the food eaten will first be processed in the stomach, and the food will be ground and mixed together like a blender through the continuous contraction and peristalsis of the stomach, which takes about 20-40 minutes; Then the ground chyme is gradually discharged from the stomach into the small intestine, which is not suitable for exercise during this time, otherwise the stomach is full of food, which may increase the weight of the stomach, which may lead to gastric prolapse in the long run. 
When chyme enters the small intestine, various nutrients begin to be absorbed, and since the small intestine is about 5 meters long, proper exercise at this time can help to quickly distribute the chyme throughout the small intestine, thus promoting the absorption of nutrients. At the same time, the energy substances such as blood sugar and fat absorbed into the blood will be consumed at an accelerated pace during exercise, which helps to avoid excess energy, which can not only avoid the occurrence of high blood sugar, but also prevent the accumulation of excess fat and cause obesity.
It can be seen that it is better to start exercising 45 minutes after meals, and 30-45 minutes to exercise time, because this period is the time when the small intestine absorbs a large amount of nutrients, and the benefits of exercise during this period can be maximized. So, how do you calculate the time 30 minutes after eating? 
If your entire meal time is 15-20 minutes, if you want to exercise after eating, you should start 25-30 minutes after putting down the dishes and chopsticks. Do you understand?
