Switch on your metabolism

"Research conducted by John Ivy, Ph.D., at the University of Texas in Austin, shows that including some protein in carbohydrate drinks turns on a metabolic switch that increases insulin secretion and stimulates uptake of both protein and carbohydrate in muscle cells. Such drinks are known commercially as metabolic optimizers and can found in health and bike shops." Not only are the drinks a good post ride supplement but some riders are also having success after drinking them during long events.
