Now Bill has lost 71 pounds—the most among the six challengers—and no longer needs his medications. "I feel great," he says. "For me, the numbers on the cholesterol and the blood pressure [tests] and getting rid of the medication, that's bigger than the weight. It's the health."
Bob explains that men tend to lose weight faster than women because of the hormonal advantage in the way testosterone acts on fat. "Women almost have to be perfect. A woman has to be active at least five to six days a week," he says. "Men can get away with three or four times a week and have even better results."
