Online 'Office Hours' on Low-Carb Diets

Obesity rates are on the rise in the U.S. and some believe the answer to weight loss is a low-carbohydrate diet. Dr. Eric Westman, director of Duke's Lifestyle Medicine Program, has studied the benefits of low-carb diets and written a book, "The New Atkins for a New You," which updates the popular Atkins diet. In a live, "Office Hours" webcast interview, Westman answers your questions about Atkins and other weight-loss programs.
