What exactly do human waste products (1, 2, and sweat for good measure) actually contain in the way of water percentages, other fluids, and especially leftover nutrients and fuel? Are there fats, carbs, and proteins that humans excrete but other animals can use for energy? Why exactly are those things not digested and/or what do humans lack that is necessary to do so? Or a much simpler question: how many calories (not food calories) does 1 lb of human shit contain?
