Title: Comparison of High Monounsaturated Fat and High Carbohydrate Diets on Glycemic Control and Cardiovascular Risk Factors in Type 2 Diabetes
Brief Summary: The purpose of this proposed randomized, controlled trial is to compare the effects of high monounsaturated fat diets and high carbohydrate diets on body weight, body composition, glycemic control, plasma lipids, and other cardiovascular risk factors over a period of one year. At present, no such studies of free-living subjects have been performed. The specific aims of the proposed project are to test the hypotheses that (1) a high monounsaturated fat diet will produce greater weight loss/body fat loss and more successful weight maintenance than a high carbohydrate diet and (2) a high monounsaturated fat diet will result in an improved lipid profile and better glycemic control than a high carbohydrate diet.
