A primary aim of the current proposal is to compare the effect of daily consumption of healthy lean protein as either whey protein (2 meals per day) or whole food (25% of total daily caloric intake) consumed as 6 small meals throughout the day, one of which is consumed immediately following exercise training (within 30 min) and another 2 hours prior to going to bed at night, over a 16 week period on muscle and fat mass, cardiovascular health, aerobic fitness, glucose, insulin, blood lipids, heart rate and muscle strength in overweight men and women.
