New research from Duke University suggests that by 2030, 42 percent of Americans may be obese; that's an additional 32 million people within the next two decades.
Severely obese individuals are at highest risk for the health conditions linked to the excess weight, resulting in substantially greater medical expenditures and rates of absenteeism.
Keeping obesity rates level could yield a savings of nearly $550 billion in medical expenditures over the next two decades.
