I watched it, I was hoping to learn something new. But I agree, it was the same old thing, and a lot of "We don't know"s. I've heard about the 6 month mark as well, though this was the first time I'd heard about it being 6 months, as the other studies showed shorter periods. Previous studies have shown that low carb and low fat and/or low calorie result in about the same amount of weight loss over a given period, though the low carb diet results in an initial weight loss faster, then it levels off, and in the end, all groups lost equally. The same studies also show that of those that regain the weight, the low carb group regains it faster than the low fat group. Seems strange, doesn't it.
The only thing remotely interesting about the program was the study on low carb foods and how accurate their labels were. It was impressive that the Atkins brand products were very true to their labels, but not surprising at all that other brands were so far off base. We had recently reported the news about Low Carb Emporium bagels that claimed 15 carbs, but actually had a whopping 55 carbs per bagel. It reminded me of the episode of Seinfeld, where the gang was loving fat free yogurt from some new yogurt stand, and everyone was eating it - and gaining weight. Then they found out it was loaded with fat, anyone remember that?
