I too, wonder why these studies don't show the dramatic results that people here, or on Dr. Bernstein's forum report. I think it's because they can never bring themselves to do a truly lowcarb test - like this one, if you read it the way I do, there were lots of carbs in both, just higher glycemic in one. With Dr Bernstein, you not only limit the carbs, you totally avoid the high GI ones. I'm sure that if they studied that, they would find huge decreases in Hc1a, fasting bg, pp bg, would have to decrease medication, etc. Why don't they do this? Haven't a clue. Bill
