The LIPP program is designed to promote weight loss that is 5-10% of current body weight. The 3-month weight loss phase consists of aerobic exercise training with diet and behavioral counseling to induce weight loss as was successfully achieved in prior studies. The women will wear heart rate (HR) monitors (Polar Electro, Woodbury, NY) during each exercise session so that they have visual feedback of their personalized target heart rate goal. Our Lifestyle Coaches will enter all foods eaten into our diet database (NDSR, Minneapolis, MN) to facilitate analysis of calorie, and macro/micro nutrient intake. Subjects will generate photos from before and after the meal in order to estimate the amount of food that was eaten. Data will be obtained at baseline, and at 2-week intervals during the initial 12-week supervised weight loss period.
