Brief Summary
The investigators hypothesize that consumption of potatoes is a healthy adjunct to lifestyle intervention in overweight and obese glucose intolerant adults. We will evaluate the effects of the consumption of potatoes (high or low resistant starch) vs. commonly consumed carbohydrate sources on glucose tolerance; and ( the extent to which potato consumption alters markers of lipid metabolism and inflammation in the context of a lifestyle intervention program.
