How long after a meal should you do aerobic exercise?

The safest choice is to wait 1 to 2 hours after a regular meal before doing medium-to-high-intensity aerobic exercise. If you have a small snack, you can exercise in 40 minutes to an hour. For a full meal with high oil and fat, it is recommended to do more than 3 hours.

I have met many friends who have fallen into the trap in running groups before. Last week, there was a young man who had a meal of heavy oil and spicy Chongqing hot pot for lunch, which made his belt loose. He followed the group for 10 kilometers after resting for less than 50 minutes. After finishing the first kilometer, he held on a tree trunk and vomited. Finally, he suffered from gastroenteritis all afternoon, and it took him three days to recover before he dared to run again.

In fact, there is no hard and fast rule for this time. It all depends on what you have eaten and the tolerance of your gastrointestinal tract. If you eat half a corn and drink a glass of Americano as a snack in the afternoon, there is no need to wait for two hours. The burden on your gastrointestinal tract will be small. You won’t feel panicked when you stand up and take a few steps. It’s no problem to just go for a brisk walk or aerobics.

I used to hear elders say that exercising after meals can lead to gastroptosis and appendicitis. In fact, there is no clear clinical evidence to support these claims. Gastroptosis mostly occurs in people with loose ligaments and long-term overeating. Appendicitis is basically caused by fecal stone blockage. It has a very low correlation with occasional exercise after meals. Don’t scare yourself.

If I usually eat light multi-grain rice and stir-fried vegetables for dinner, I usually take a break of one and a half hours and then go ride a spinning bike. I have never been short of breath.； If I catch up with friends to have a barbecue buffet on the weekend, I usually stroll around the streets for two hours, wait until the fullness in my stomach is gone, and then go for a jog, and I haven't had any problems. If you are really not sure, you can start with low-intensity slow walking. Walking slowly for 10 to 20 minutes immediately after a meal will not hurt your stomach and intestines, but it can also help promote digestion. Just wait until your body adapts and then gradually increase the intensity. There is no need to wait with a stopwatch to count the time before you dare to move.
