Each week during Cycle 1 and on Day 28 of each additional cycle, you will complete 2 questionnaires that will take about 15 minutes to complete. You will also have your body weight measured and be asked about your normal food intake. Your body composition will be measured using measurements that include body weight and height, skin fold thickness, and bioelectrical impedance using the Tanita body composition monitoring scale. This is a non-invasive method to measure total body water, total body fat, and total body lean mass. Researchers will measure how much energy your body uses while at rest. You will also have timed test that will involve your participation where at your fastest speed you will be asked to walk 25 feet and walk back.
