Over the past year, Pennsylvania Governor Ed Rendell has lost more than 62 pounds, all without fad diets, personal trainers or appetite suppressants. Instead, he's opted for a simple plan of more exercise and smaller portions. Gary Foster, director of the Center for Obesity Research and Education at Temple, says that if the governor's program works for him, then it's the right one. "What's elegant about the approach is its simplicity," Foster says. "Many people get tripped up by the complexity of calories, carbs, sodium, cholesterol, and we end up asking patients to go through mental gymnastics every morning."
