Smoke,
I guess my thinking on the ancient diets (for lack of a better term) is that they help people justify eating things they want to but shouldn't. "Hey, I'm gonna try the New Polar Diet, I can eat 90% fat and still brave the arctic winters and kill polar bears with a spear and live a long and healthy life. Since blubber is hard to find, I'll just swing into McDs for lunch. And just so I don't get fat, none of that whole wheat crap for me." You get my drift.
Too much of what people think about nutrition is driven by advertising. High Protein-good, Low Carb-good, Low Fat-good, etc, etc. It's not that simple. I love the big "Fat-Free" label on candy packages like that makes it healthy.
I guess some aspects of the Paleo diet are good, the percentages of protein, fat, and carbs wouldn't work for me. Sure sounds cool though-Paleo Diet-advertising?
