Hawaii has lowest obesity rate in the nation, followed by Colorado, Massachusetts, New Mexico, and Nevada, a new Gallup poll shows.
At the other end of the spectrum, the survey showed West Virginia leads the nation in obesity (with 37 percent of residents), followed by Mississippi, Delaware, Arkansas, and Oklahoma.
The findings, from daily interviews conducted January through December 2015, are based on U.S. adults' self-reports of their height and weight, which are then used to calculate Body Mass Index (BMI) scores. Americans who have a BMI of 30 or higher are classified as obese.
The national obesity rate reached a new high of 28 percent in 2015, up from 25.5 percent in 2008, when Gallup began tracking obesity. Fourteen states had statistically significant increases in their obesity rates from 2008 to 2015, while no state registered a decline. Maine, West Virginia, Idaho and Oklahoma experienced the sharpest upticks in obesity.
Of the 18 states with obesity rates of at least 30 percent, all but one are located in the South or Midwest. Meanwhile, all 11 states with obesity rates below 25 percent are located in the Northeast or West.
