The Latest On The Glycemic Index

David Ludwig of the New Balance Foundation Obesity Prevention Center and colleagues recently published a study in the Journal of the American Medical Association.  The study compared low-fat, low-carb, and low-glycemic diets.  While the low-carb diets prevailed and the low-fat diet ended up with the bronze, the low-glycemic was the easiest to follow for participants.
