It's peculiar that so many think the carnivore diet is prime cuts of meat with butter and cheese. All of those are prime products with historically limited availability. Much of the diet would be tendons, tripe, organ meats and other such cooked together with vegetables for essential potassium. What we know of traditional carnivore diets is radically unlike what most nowadays think of which is based on a highly productive industrialized farming infrastructure that was not available for most of human history.
