Having said that one can adapt to a lowcarb diet and start deriving most energy from ketones. During the adaptation you might feel slugish though; but afterwards many report being more mentally alert; since you don't get the carb slowdown (turkey dinner syndrome).

Exactly. Atkins is very low carb only in the beginning, and the tough first few days are largely about withdrawals from glucose, especially as delivered by today's highly processed carb foods (including all kinds of "low fat" stuff). As you lose weight, you add the carbs back until you find the amount where you neither gain nor lose. Furthermore, it is suggested that you get your carbs from foods with a high glycemic index--they don't break down into glucose quickly. So a whole food diet with complex carbohydrates along with a varied regimen of proteins is recommended. I think this probably approximates the hunter-gatherer diet around which our physiology developed through thousands of years. It's surely feels right for my wife and me.

Heh, same here. Good food, high prices! I'll stick with the Teeter :)

I saw a show on TLC saying that youngster (boy and girls, girls much more) hitting puberty early was due to the amount of super fatty foods that they are exposed to by early (and constant) forays into McD's and such. People are getting fatter, younger.
