Didn't you say you won't eat vegetables, which are the primary stable of a primates diet?
We are in the great ape family, next to the gorilla and the chimpanzee. These animals eat huge quantities of low nutrient greens, but we can target better ones. Meat eating started with small animals and eggs (and also each other I think, I suspect monkeys got fangs for tearing into eachother), for the surplus of retonic acid and riboflavin, there was never a protein shortage in the vegetarian diet, but meat proved to be very good for our eyes and brain.
