You know I like low carb.....

I liked this quote:

Dr. Marantz and colleagues argue that if guidelines can alter behavior, such alteration could have positive or negative effects. They cite how, in 2000, the Dietary Guideline Advisory Committee suggested that the recommendation to lower fat, advised in the 1995 guidelines, had perhaps been ill-advised and might actually have some potential harm. The committee noted concern that “the previous priority given to a ‘low-fat intake’ may lead people to believe that, as long as fat intake is low, the diet will be entirely healthful. This belief could engender an overconsumption of total calories in the form of carbohydrates, resulting in the adverse metabolic consequences of high-carbohydrate diets,” the committee wrote, while also noting that “an increasing prevalence of obesity in the United States has corresponded roughly with an absolute increase in carbohydrate consumption.”

But, the researchers noted, in 2000, the Dietary Guideline Advisory Committee reversed the earlier 1995 recommendation to lower fat intake, saying that it might have been ill-advised and might actually have some potential for harm.

They quoted the 2000 committee statement that "an increasing prevalence of obesity in the United States has corresponded roughly with an absolute increase in carbohydrate consumption."

UPDATE

Dr Briffa gives a really good analysis of this study.
