The Inuit also traditionally live in the Arctic wearing Caribou and seal skin pelts. They are the hardest m-f'ers I've ever seen, and I can guarantee that a large part of their "health" is due to the tremendous amounts of energy used by the body just to stay alive.
Eat like an Inuit and live in Florida and you'll probably resemble something more like a manatee than a man.
I think the "not too much" is also redundant. If you eat bacon and eggs, your hunger will tell you when to stop. It's the non-food (sugar and grains) that mess up our hunger signals (mainly insulin).
He also has qualifiers on what "food" is, most of which are reasonable; stuff you can pronounce, stuff that your great-great grandmother would recognize as food (put away the chemistry set!)
Michael Pollan says it best: "Eat food. Not too much. Mostly plants."
