Poop Poundage

Hey Matt:

Something I've been always wondering. Is there an average percent of human feces every time a person goes to the bathroom (in lbs., oz., etc.)? And if there is, can you notice the weight difference on a scale when you weigh yourself right after you go?

Sounds like diet desperation to me, Art. Looking for any loophole to prove that you've shaved off a bit more flab? Well, we checked with Dr. G, staff gastroenterologist, and he just laughed and looked incredulous and told us to go eat some fiber. Once we'd cornered him by the colonoscopy machine and poured on the charm, he was ready to talk. Your answer depends mainly on your type of diet. For a typical Western diet, the science guys have calculated the average bowel movement to weigh 200 grams. About seven ounces.
