Mostly it’s an issue of abundance in calories. Historically most people have worked such physical jobs in environments with limited food supply. In that environment it’s way harder to get obese, regardless of genetics or gut biome.

This is the same logic a lot of vegans use. Food is unlimited nowadays, so it doesn't make sense to indulge in the most resource intensive foods(meats) because it isn't feast or famine anymore.

Nothing we do nowadays is "natural" or "the way our ancestors did it" so its weird how folks cling onto "caveman diet" like it's some amazing thing. It's just excess consumption and a status symbol.

Prehistorically we straight up starved a lot of the time. Being able to get fat when in a time of abundance was an evolutionary advantage, we'd need that for the lean times. The fact that we are never in lean times is the problem, we're simply doing what our body was built to do.
