Your body is a bioreactor that constantly transforms stuff into other stuff, pumps stuff from one thing into a different thing, opens and closes valves, sends tons of electrical impulses everywhere and needs to keep itself toasty at a very exact temperature in order for all these other processes to work.

That requires a lot of energy input.

That’s the baseline fuel requirement for your body. Physically moving your *limbs* around surely factors into it, but just to a very small degree. Accordingly, moving your limbs around *a bit more* does not increase your energetic requirements by a lot.
