Basically the title. I saw this thing about how much you have to exercise to burn off certain foods and was wondering how your body burns so many calories by doing nothing.

Just chipping in, your brain is very very hungry. It uses about a third of your base metabolic rate. So just to be awake and thinking for 16 hours a day takes 600 calories. That’s without any movement. Neurons need to maintain a precise chemical balance to work properly and part of working involves moving chemicals effectively “upstream” (against a concentration gradient) only to release them again when needed.
