Many heavy children and their parents are looking for ways to reach a healthier weight, but there are few places to go for guidance. Now a new study suggests that kids can trim down in a six-month weight-loss program that combines group support along with parental help at home. "If all the kids across the country were exposed to a program like this, we could significantly reduce childhood obesity," says lead author Gary Foster, director of the Center for Obesity Research and Education at Temple.
