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?
The idea that plants are healthy is modern propaganda.
We have a gallbladder like other carnivores (and unlike any herbivore) and our cecum (appendix ) is vestigial, most people even have it removed. we can extract minimal nutritional value from plants because of this. Meat on the other hand is 100% bio available and is the reason we have large brains and small abdomens. we literally traded plants for brains.
Early humans where fit because the alternative was being eaten by a fucking wolf
That is not entirely true. The anthropological and archaeological evidence shows that humans have been omnivores since they first existed, the exceptions being cultures such as the Inuit that live in areas where plants are scarce, but even they eat some plants.
Note that it is true that once humans (really pre-humans) started eating more meat, they were able to extend their range as meat is a denser source of nutrients, but humans are still omnivores rather than obligate carnivores.
