Obesity, disability, and mortality: a puzzling link.

The idea that obesity and frailty are connected is not new. More than 400 years ago, Shakespeare masterfully expressed this concept with Falstaff's words. However, as new scientific evidence for a direct causal pathway between obesity and frailty accumulates, we need to begin a dialogue on the consequences for the aging population of the marked escalation in obesity witnessed over the past 25 years.
