Sam Elliott,age 57, has gained 30 pounds since his retirement 2 years ago. The most active thing he does each day is “puttering around” and “walking to the end of the driveway to get the mail.”His diet includes juice, oatmeal muffin, and coffee with cream for breakfast; donuts and coffee with friends midmorning; a bologna-and-cheese sandwich with chips and a root beer for lunch; and cheese, crackers, and wine before a dinner of meat, potatoes, vegetables, and dessert. He tells the nurse,“I have never had to diet. I just don’t know how to get this weight off.”
