How long to run after a meal is mainly related to the amount of food eaten, if it is a normal diet, it is recommended to run after half an hour to an hour after eating, at this time the food eaten in the stomach is basically emptied almost, when running will not cause a lot of burden on the stomach. If you go running immediately after eating, it is likely to cause stomach prolapse, and you will have stomach pain and even nausea and vomiting. But you can’t go running on an empty stomach either, this will cause hypoglycemia at night, which is also very bad for your body. The best advice is to eat dinner five or six minutes full, after eating half an hour to an hour you can go out running, so that the body does not have the effect of discomfort, but also particularly suitable for weight loss.
