The most obese state in the country has almost double the proportion of plus-sized citizens than the least obese state, according to a new survey.

The newly-released Gallup-Healthways Well-Being Index shows Colorado has the fewest obese citizens in the country, with 18.7 percent of its population obese. On the other side of the
belt loop, West Virginia reported the highest obesity rate, with 33.5
percent of its population being obese.

Colorado is the only U.S. state with an adult obesity rate
smaller than 20 percent, the report found. The Centennial State has held the title of thinnest state for three years running, according to
Gallup-Healthways.

For West Virginia, the new numbers mark the third year in a row as the state with the highest obesity rate. But according to the latest figures, the state's obesity rate is down from 35.3 percent in last year's survey.

Obesity rates in each state were not statistically different in 2012 when compared with findings from 2011, with the exception of four states: New Jersey and Georgia, which showed increases in obesity rates...North Carolina and Delaware, which saw decreases.

Obesity rates continued recent regional trends and were highest in Southern and Midwestern states and lowest in Western and Northeastern states.

The survey found the national obesity rate held steady at 26.2 percent in 2012, compared with 26.1 percent in 2011, but is still higher than the 2008 U.S. obesity average of 25.5 percent.
