I’m talking about before we figured out we could grow vegetables and fruits. Early humans are often shown as being fit and in shape, yet our diet pretty much only consisted of meat. We were hunters. So why the hell were they so fit? I thought a healthy diet mattered more than just being active constantly?
Meat and organs is an almost complete food source. You’ll get sufficient vitamin D with lots of sun. Throw in berries and eggs and other foraged items and it’s a very healthy diet.
