Low Glycemic Load Diets in Latino Children at Risk for Type 2 Diabetes

The purpose of this study are to: 1. compare two diet plans - a low-glycemic load (low-GL) diet and a low-fat diet. A low-GL diet is expected to keep blood sugar levels more normal, and because the sugar levels stay normal, prevent rapid rises of insulin in the blood. We want to test if Hispanic children at-risk for type 2 diabetes who are given a low-GL diet will have less insulin resistance, will lose more weight, and will decrease their chance of getting type 2 diabetes. 2. compare the effects of Low-GL and high-GL meals on appetitive, hormonal, and metabolic responses of obese Hispanic youth under controlled, standardized conditions. We want to test if children fed low-GL meals would have lower glucose and lower insulin responses, report less hunger and consume less energy than those fed high-GL meals.
