So... a 2000 calorie diet would have given 150 grams of carbohydrate. Pretty much Zone ratios, more than Atkins. Except that when I followed the Zone to the book it put me under 1500 calories a day, pretty severe calorie restriction if you consider that I lose weight at 2000 calories a day on my current keto diet (which is one reason that I make sure to eat well above that).

A moderate intervention, giving moderate benefits. Only a six week intervention--would they continue to improve, or are the improvements all tapped out?

Since the article on science daily wasn't specific about just how low carbs should be cut, maybe people will misread this and go all the way to Atkins. One could hope.
