About
High levels of the hormone insulin are associated with risk for heart disease and diabetes, and may make it hard to lose weight. The types of food eaten may affect insulin levels. The purpose of this study is to determine if manipulation of dietary carbohydrate content improves insulin sensitivity (Si), augments weight loss, and promotes weight loss maintenance in healthy adults.
