I thought the same thing, but turns out the body is really damn complicated. Worth skimming the papers they link in the video - basically your body adapts over the course of ~6 months or less if you become more active by saving energy elsewhere. Things like inflation and basic metabolic functions can burn way more energy than they need to.
