Summary
Brief summary
To investigate the hypothesis that reducing the glycemic load of the diet will improve changes in body composition and cardio-vascular risk factors. The study compares a conventional reduced-fat, high carbohydrate diet with 3 means of reducing glycemic load: changing the carbohydrates to low-GI choices, replacing some of the carbohydrate with protein, or combining both effects to produce the lowest glycemic load.
