So I was poking around YouTube looking at videos about the Paleo/Primal lifestyle, and ran across a video by Dr. Joel Fuhrman, M.D. His big hobbyhorse is that we need to eat "nutrient-dense foods." Sounds pretty Primal to me.
I was with him right up until he started saying that meat is bad for you and that fat causes fat. At that point, he lost me. Until then, it looked pretty promising.
But maybe I hadn't understood correctly. So I looked up his book, "Eat to Live," on Google Books. It had a limited preview, and again, it looked pretty promising right up until he made the unsupported "fat causes fat" assertion, when he said, and I quote:
"Fat is an /appetite stimulant/: the more you eat, the more you want."
BZZZT! Wrong! Anyone who's been eating Primally for any length of time knows that fat causes *satiation,* not hunger or appetite. I know from experience: five pork rinds, and I don't want any more because I have no appetite left. Carbohydrates are the appetite-stimulating culprits, as we all know.
He talks a little bit about how insulin stores fat, and that's fine, because it's mostly true, but he misses that insulin stores sugar as fat, not fat as fat. He misses that insulin's job is to turn sugar into fat and store it in fat cells. (As far as I understand it, insulin does not interact directly with dietary fat.)
It drives me so crazy when I read stuff like this, from someone who is obviously intelligent but still unable to hit the broad side of the scientific barn.
