Modern humans eating like 2k calories is an abberation. First of course they just get fat off of it, but also our endocrine system have adapted for inefficient calorie usage and extraction.
If you fast regularly, go through long periods of low caloric intake like your ancestors did, your body will very quickly learn to be efficient and not waste a dime.
This is how all tribal humans survive. Their average caloric consumption is way below 1000.
