Tail end of the Atkins diet idiocy?

A new study in JAMA (Low-Fat Dietary Pattern and Weight Change Over 7 Years) concludes that low fat diets rich in fruits, vegetables and whole grains don't cause weight gain. What a surprise! As the Wall Street Journal reports (Carbs May Not Weigh You Down):

The lead study author, Barbara V. Howard, president of the MedStar Research Institute in Washington, said some advocates of the Atkins diet and other low-carbohydrate diets had suggested that low-fat diets advocated by cancer and heart-disease prevention groups might be part of the reason behind the growing number of overweight Americans.

Maybe bacon isn't a miracle food after all.
