Do you burn calories when you are pooping?

Answer 1

The various constituents of poop (live and dead gut microbes, undigested food particles, fiber) do contain calories. About 50 to 60 percent of poop consists of gut microbes. Since gut microbes consist of fat and protein, at least half of poop contains calories.

It's estimated that, on average, people absorb about 80 percent of calories consumed. In addition, each gram of gut microbes (dry weight) represents 5 kcal of energy that does not get absorbed into the bloodstream. Instead, that heat diffuses into the body.

Answer 2

calories are a measure of the amount of energy that the body can extract from food through digestion. if the body digests food properly then a bowel movement will not cause a lose of calories. if the food exits the body undigested then the person will lose calories. calories are lost through physical exertion. contracting the sphinctor muscle to deficate uses some minimal amount of calories, like other forms of exercise.

Answer 3

No.
