I'm looking for studies showing where food ends up after consumption, i.e., % converted to thermal energy, stored as fat, released as excrement, etc. How does fat/protein/carb mix, fiber intake, water intake, total calories, total pounds, frequency of meals, body type, exercise frequency/duration/intensity, sleep affect this? In practical terms, if someone releases more excrement in the morning or goes twice in a day when they usually only go once, is that because they ate more calories, ate more weight in food with the same caloric content (which may imply a different mix of macronutrients), there was just more "waste" in what they ate, is it just random...why???
I don't expect perfect answers, but interested in any available research or commentary. I enjoy reading the diet threads and I'm fascinated by these questions, but I believe the nutrition practitioners, coaches, doctors and scientists claim to know a lot more than what they can really prove.
