Yes, it sounds hokey to me. I've not seen any legitimate research that would support this idea. And the eras in which these various blood types have supposedly evolved is without substance as far as I can ascertain. Aside from lactose intolerance I can see nothing that is demonstrable in the site. I think that all of us should balance our protein intake and not over eat the beef fat. But I also think many of us have already proven that the Atkins concept works just fine.
Thanks for the interesting post though. I love to read anything interesting.
