how many calories does farting burn

Farting does not burn a significant amount of calories. Although there was an internet claim that one fart burns 67 calories and that farting 52 times a day could burn 1 pound of fat, this claim has been debunked by experts. Farting is a passive activity where the muscles actually relax to release gas, so it does not require muscle work that would burn calories. Technically, if you strain to push out a fart, you might burn a very small number of calories (around 1-2 calories), but this amount is negligible and nowhere near enough to contribute to weight loss or measurable calorie burning. Breathing alone burns more calories than farting does. The digestive process itself does use energy (about 10% of daily calorie expenditure), but farting as the release of gas does not significantly burn calories. So in summary, farting burns essentially no calories or at most a negligible amount that is too small to be meaningful for weight loss.
