Question

when you fart how many calories

Answer 1

Actually when you fart  , you do not burn calories.
Specialists say flatulating is a inactive action — so it most likely doesn't consume any calories whatsoever. At the point when you fart, your muscles restful and the pressing factor in your gut pushes the gas out without exertion. You consume calories when your muscles work, not restful.

Answer 2

Farts don't cause the burning of any calories. Rather, the exit of gases from the body is considered a very negative bodily function as when you fart, your muscles relax, gas pressure in the intestine expels excess gas, while calorie burning occurs from muscle activity, not inactivity.
