According to LifeZette:
It is no secret that Americans have an obesity problem. The Centers for Disease Control and Prevention (CDC) reports that more than one third of U.S. adults — or 36.5 percent of us — are classified as obese.
Now a new study has found that obesity is responsible for shortening the lifespan of humans more than smoking.
A team of researchers from Cleveland Clinic and New York University School of Medicine found that obesity led to “as much as 47 percent more life-years lost than tobacco,” noted Science Daily — “and tobacco caused similar life-years lost as high blood pressure.”
