Low-Carb verses Low Fat

Following are three referenced articles in three well respected journals:

1. March 7, 2007 - The Journal of the American Medical Association (JAMA) published an article showing that, at twelve months, women assigned to the Atkins (low-carbohydrate) diet lost more weight and experienced more favorable metabolic effects than did women assigned to follow the LEARN, Ornish or Zone diets.

2. July 17, 2008 - The New England Journal of Medicine published an article describing a two-year study of men and women in Israel. The study showed that, compared with the low-fat diet, the low-carbohydrate diet produced greater weight loss and had more favorable effects on lipids. The authors concluded that low-carbohydrate diets may be an effective alternative to low-fat diets.

3. August 3, 2010 - The Annals of Internal Medicine published an article describing a two-year low-carb vs. low-fat study of men and women in the United States. The authors concluded, "Successful weight loss can be achieved with either a low-fat or low-carbohydrate diet when coupled with behavioral treatment. A low-carbohydrate diet is associated with favorable changes in cardiovascular disease risk factors at two years." (article source)

All three studies showed that a low-carbohydrate diet is effective for weight loss.

All three studies also showed metabolic effects, including an increase in HDL cholesterol, improved with the low-carbohydrate diet. 

And while the first study lasted a year, the last two studies covered a two-year span.

This demonstrates the benefits of a low-carb lifestyle are not limited to a few weeks or months.
