Efficacy and safety of low-carbohydrate diets

An analysis of hundreds of published studies on the safety and effectiveness of low-carbohydrate diets found that there is not enough scientific evidence for or against the use of these diets. “This analysis is important because it clearly documents the lack of hard scientific data to support the use of low-carbohydrate diets, and identifies areas that need further research. Both the public and health-care professionals should pay close attention to this wealth of data, collected from many different research groups, because it is the most comprehensive review of published science on the subject to date,” says Robert H. Eckel, M.D., the chair of the American Heart Association’s Nutrition, Physical Activity and Metabolism Council.
