Do you poop out calories?

Total speculation on my part, but it doesn't seem logical that we'd waste 'calories'. The body excretes what we cannot use (i.e. waste product), but we've evolved to store anything we can use but can't do so right away. Calories simply being pooped out would seem to go against how we evolved. It'd be awesome though... maybe my BF% would be lower if that were the case, lol.

Feces contain macronutrients (calories). Your digestive system does not operate with 100% efficiency, and some food inevitably is excreted without being absorbed. People with a faster metabolism pass food through their small intestine faster and thus have less time to absorb all the nutrients/calories.

Fair enough. Like I said, pure speculation.

Yeah, I can vouch for this. I would have a lot of "storage" right now if there weren't calories in feces.
