As for really loud toots, the same answer applies, per medical director of the weight management and bariatric surgery program at Northwestern Medicine Delnor Hospital, Dr. Matthew R. Pittman (via Women’s Health). “Even if you experienced the most violent, explosive fart you can imagine, it would be pretty difficult to burn calories during it,” explained the doctor.
But what about if you strain to fart? Would you burn any calories then? According to Healthline, there’s a chance you might in this case, but the amount would be pretty insignificant — we’re talking one or two calories at most. “You cannot fart yourself thin. No, farting is not a practical weight-loss tool. And no, it can not be used in place of regular exercise,” stressed Dr. Pittman.
With that said, passing gas can sometimes make you feel instantly lighter and less bloated. Some of the things we eat and drink — like cruciferous vegetables, carbonated beverages, and lactose — can cause us to feel bloated. Farting is typically one way to make ourselves feel better (and lighter) in situations like these. Still, it’s important to know what your farts can tell you about your health. Here’s when passing excess gas might be a cause for concern.
