This is a very surface-level and primitive analysis. Of course the amount of energy you use varies based off of your activities and the state of your body. Never did I say I used "zero energy", you're fighting ghosts here.

Rather, my point was simple: calories-in and calories-out is correct, but the mistake evangelists of this ideology make is assuming calories-out is fixed or even a simple equation. It's not, and this is what pushes your narrative from "science" to "ideology".
