all I'm saying is go and check out the diet of the Hadzabe tribe in tanzania, the last tribe of hunter gatherers on earth apparently.

they're eating approx 2000 different types of plants over the course of a year n they ain't eating steak everyday. they eat a diverse range of meats as well when they catch it, but no ones that successful at hunting to eat meat all the time.

and take a look at the human physiology.

that's not a digestive system of a carnivore. function governs structure. and if the function of the human digestive system was to eat meat every day then we would have evolved a digestive system that looked very different to the one we have.
