AURORA, CO - NOVEMBER 13: Joshua Guillen, 10, participates in group excercise during the Shapedown program for overweight adolescents and children on November 13, 2010 in Aurora, Colorado. The 10-week family-centered program held by the Denver area Children's Hospital teaches youth and their parents ways to lead a healthier more active lifestyle, as a longer lasting weight-loss alternative to dieting. Nationally, some 15 percent of children are overweight or obese, as are some 60 percent of adults. (Photo by John Moore/Getty Images) less
