From Liz Atwood: For years we've heard about the teen and tween girls who have a negative body image. Trying to emulate the unnaturally thin models they see on TV or in magazines, they can starve themselves to death.
But a new study shows that not only girls, but also teen and tween boys, can harm their health when they become too worried about their bodies.
The journal Pediatrics recently published a study that shows a significant number of boys are using protein shakes and steroids to build their muscles. More than a third of the high school and middle school boys in the study reported using protein shakes; nearly 6 percent said they used steroids. Even more shocking, nearly as many middle schoolers as high schoolers reported using steroids.
