A recent survey by the Center for Disease Control and Prevention says adult obesity in the United States isn't budging.
The national survey found 13 states with very high rates of obesity last year. At least 30 percent of adults in those states were very obese.
"A plateau is better than rising numbers. But it's discouraging because we're plateauing at a very high number," said Kelly Brownell, a Duke University public policy expert who specializes in obesity.
Louisiana and Mississippi led the list. Colorado was at the bottom of the list, with less than 21 percent.
States in the South and Midwest top the charts, many of them with high poverty rates.
The numbers have stayed roughly the same since 2008.
