ThinkstockYour best friend could be your waistline's worst enemy: An obese buddy can increase your chances of becoming obese by 57 percent, and when your bestie becomes obese, your risk shoots up to 171 percent. The domino-effect data is harsh but makes sense: You live, laugh and love together? Surely you eat and exercise (or not) together too.
About one-third of all American adults (that's 33.8 percent!) are obese.
Consider these stats: The number of so-called "fat states" with an obesity prevalence of 30 percent or more has increased to 12 states in 2010. (Thirty-six states had a prevalence of 25 percent or more.) That's compared to 2009, when only nine states had obesity rates of 30 percent or more. Back in 2000, no state had an obesity prevalence of 30 percent or more.
Translation: America's obesity epidemic is steadily getting worse. Much worse.
