Noted: So what?s the best way to stave off that weight gain? Chad Cook and colleagues at the University of Wisconsin have done research suggesting that it might not be exercise. Their study of 443 adults ages 40 to 60, presented at a recent meeting of the Obesity Society, found that even those people who habitually burn more daily calories than predicted for their age and body weight are not protected against holiday weight gain. Cook notes that 75 percent of participants gained at least some weight and nearly a fifth put on 4.4 pounds or more.
