Mediterranean Style Diet and Low Glycemic Responses

subjects will consume the same quantities of metabolizable CHOs (270 g/d) with 135 g of CHOs assigned to the GI intervention foods. The 135 g of CHOs will be distributed as 35 g GI breakfast product, 40 g GI lunch product, and 60 g GI dinner product. Assuming an average 2400 kcal/d total energy requirement among subjects, the 270 g/d metabolizable CHO equates to 40% of total energy intake (1080 kcal/d). One-half of daily CHO intake (135 g/d) will be the same between the Hi-GI and Low-GI groups, including CHOs in fruits, vegetables, and other foods that all subjects will consume. The other one-half of daily CHO intake (135 g) will be different between the Low-GI and Hi-GI groups. Specifically, the GI values of these foods will either be \<55 (Low-GI group) or \>70 (Hi-GI group).
