Weight-Loss Groups Do Better
Peer pressure isn’t always a good thing, but a study found that being part of a group encouraged people to shed more pounds than going it alone. Overweight employees of the Children’s Hospital of Philadelphia joined one of two 24-week weight-loss programs. In one, each person was paid $100 per month for achieving a personal weight-loss goal. In the other, a group of five was awarded $500 if some or all of its members reached their personal targets, to be distributed among those in the group who reached their goals. Those in the group-based incentive program lost an average of 7 pounds more than those in the individual program.
