How much fat does your body store from a meal and how much do you shyt out?
Does it hold onto as much fat/cals as possible and then excrete the rest, or does it hold on to all of it and poop out the waste from previous meals?
Basically, if you eat a whole pizza, does your body hold onto 99% of it, or 75% and poop our 25%.
Surely there is no way your body could absorb the whole pizza... or can it?
