Childhood obesity is a major health issue in pediatric practice. The old idea that "a chubby baby is a healthy baby" is not necessarily the case. Social stigmas and recidivism surrounding obesity make addressing families and their children difficult; however, with early intervention, treatment can be successful.

This article summarizes significant research .conclusions about the relationship between physical activity, obesity, and health. It also provides practical strategies for helping obese patients integrate physical activity into their lives.
