Study Description
Brief Summary:
The purpose of this study is to determine the effects of a dietary fiber, resistant starch, on insulin sensitivity. Low insulin sensitivity is a risk factor for some diseases including type 2 diabetes and heart disease. This study will show if consuming resistant starch can help improve insulin sensitivity in overweight and obese people.

Condition or disease Intervention/treatment
Insulin Resistance Other: Hi-maize starch (Low dose) Other: Hi-maize starch (High-dose) Other: Control (starch)
