How long can I run after eating dinner? This varies from person to person, and also has a lot to do with the amount of food eaten. If it is a normal diet, it is recommended to run half an hour to an hour after eating, when the food eaten at dinner is almost emptied in the stomach, and running will not cause a great burden on the stomach. If you go running immediately after eating, it may cause stomach prolapse, stomach pain or even nausea and vomiting, but you can’t run on an empty stomach either, which will cause hypoglycemia and is not good for your body. The best advice is to eat less dinner, eat a fifth full, and go out running half an hour to an hour after eating, so that there is no discomfort, and it is also more suitable for weight loss. Two hours after eating can do fast running or strenuous running exercise, an hour or do jogging or brisk walking is better.
