Overall, more than a third of adults are obese but rates vary by state. The latest figures are based on a 2011 telephone survey that asked adults their height and weight. For the first time, households with only cell phones were included.

State rates remained about the same although states with very high rates went from nine to 12. At least 30 percent of adults are obese in Alabama, Arkansas, Indiana, Kentucky, Louisiana, Michigan, Mississippi, Missouri, Oklahoma, South Carolina, Texas and West Virginia.

Colorado was lowest, at just under 21 percent, and Mississippi was highest at nearly 36 percent.

The Centers for Disease Control and Prevention released the figures Monday.
