This question is probably heading in TMI territory, but does that mean that someone that ate nothing but lard & water would cease having bowel movements? Lard is pretty much 100% calories, and if the intestines have 100% calorie absorption, there should be nothing left at the end, right?
You are never safe assuming that extremes act the same way as averages. It’s more likely that if you could get yourself to eat nothing but fat and water you’d have diarrhea.
Answers about the body rely on everyday conditions. Pathological conditions (diseases, injuries, drugs, single-food diets) are going to give you pathological answers.
Thank you, that is a great link.
