I low-key hate the “calories in vs calories out” mantra because I believe it tends to disregard an important source of “calories out:” the ones that don’t get absorbed in the intestines and that you poop out instead. It’s still somewhat early days for the science, but there’s increasing evidence to suggest that a lot of the difference between skinny people and fat people isn’t necessarily that their calorie intake or calorie burn is wildly different, but that fat people’s digestive tracts are better at absorbing all the calories.
