Wow, a whopping 6 pounds in 2 years.
I think it is interesting that WeightWatchers was compared with counseling and a nutritionist, because I'm pretty sure that just giving someone a placebo for two years AND telling them it is a new weight loss drug would have worked as well or probably much better than WW (and certainly would've been cheaper). I've seen that experiment performed in a documentary and people lost more weight in a shorter period of time. The placebo effect is pretty powerful. And we all know how stuck in the Ancel Keys paradigm the average nutritionist is. Or how about instead of receiving "counseling" and a nutrition "expert" they were told to religiously read Mark Sisson's and Richard Nikoley's blogs and listen to every Jimmy Moore and Robb Wolf podcast?
I guess Ayres is impressed with the fact that the study was published in JAMA, hence "rigorous". It is a classic catch-22 situation. Low-carb diets are inherently unhealthy according to the AMA, hence they are practically impossible to get funding for, and even if carried out, don't have a chance in hell of getting published in JAMA, proving they are "rigorous". Welcome to the circle-jerk known as nutrition research.
