It's a function of metabolism. Human physiology is adept at storing fat. You have thyroid, TSH, ghrelin, etc., all play a role. One of the upsides of IF (5/2) is that you don't downreg your thyroid.
People with ridiculously fast metabolisms can have crazy transit times (motility) but then they are not storing excess calories like your fatties.
Your body will utilize what it can and store the rest. Isolating kcals to a single meal boosts ghrelin which increases storage as well as hunger.
