Thought provoking, non-inflammatory website (at first glance). "They are really hybrid diets pairing the animal foods of a savannah hunter with the plant foods of chimpanzees and mountain gorillas." Did Grok really eat the equivalent of big assed salads? I don't think it matters for our practice. IMHO they are very healthy and delicious.
"The available plant foods were mainly the pith and underground storage organs of starch-containing plants." I eat potatoes several times a week. They don't seem to raise my blood sugar much. Of course, I pile on the butter. But I can't buy calling potatoes one of the healthiest carb sources. Compared to yams, etc., I just don't see any evidence of that.
"These Diets [paleo] Aren’t Tasty" - The menus he slams (from Robb Wolf) sound very tasty to me, although I like the heartier ones with more fat from Primal much better, especially in cold weather. Kind of a matter of taste.
The suggestion that paleo diets are too high in protein isn't really true of primal as defined by Mark, although many Groks do eat a high amount of it. I have not read Perfect Diet. Would be interested in learning more about the rationale for keeping protein consumption low.
