The Motley Fool's health-care show Market Checkup focuses this week on obesity, one of America's largest health-care concerns. Recently classified as a disease, obesity leads to serious health problems, including diabetes, heart disease, and stroke. Currently 35% of adults in the U.S. are classified as obese, but more troubling, one out of three children is as well. All told, obesity adds $190 billion in medical costs to the system, but efforts to tackle this growing problem are increasing.

In this video, health-care analysts David Williamson and Max Macaluso discuss the impact government-mandated changes may have on promoting a positive change on American lifestyles and whether investors in the affected companies should be concerned about these new regulations.
