For our February look at diets in the news, one deserves a special note.

The RealAge diet and lifestyle has been endorsed by a celebrity with her own television show. Not just any celebrity. Oprah Winfrey. As USA Today reported, within days of the diet doctors appearing on her talk show, their latest book and dvd, YOU: On a Diet, and their earlier book, YOU: The Owner’s Manual, sat in the top three spots on the best seller list of Amazon. Their most recent book remains on the New York Times Best Seller list.
