Study: Being in Shape is Far Better for Longevity than Being Thin

A new study from the University of Virginia examined the relationship between aerobic fitness, body mass and longevity. It was the largest, most thorough study on the issue to date, analyzing a vast amount of earlier research. It found that being out of shape doubled or tripled the risk of dying prematurely, whatever a person’s body mass index or age was. It also found that if someone had obesity but was aerobically fit, that person was about half as likely to die young as someone whose weight was normal but their aerobic fitness was low.
