Good food, good health with Tony Barber. Good food and exercise. That's the key to feeling good about yourself. You don't have to run. A brisk walk several times a week will work wonders. And when it comes to food, forget gimmick diets. A good rule, a little bit of everything, not too much of anything. The important thing is stick with it and you'll be a winner.
