A Gallup poll has revealed a very disturbing fact about obesity rates in the United States: at least 20 percent of each state is obese.

Colorado has the lowest obesity rate at 20.1 percent.

West Virginia has the highest obesity rate at 34.3 percent.

States in the higher obesity range include the Southern states of Texas, South Carolina, Mississippi, Louisiana and Arkansas. Other states in this range include Michigan, Indiana, and North Dakota.

States in the middle obesity range include Missouri, Alaska, Alabama and Georgia. Maine was the only New England state in this category.

States in the lower obesity range include Florida, California, and every state in New England except for Maine.

The poll results are based on 177,237 interviews conducted daily from January of this year through June.

This poll is part of the Gallup-Healthways Well-Being Index. It uses self-reported height and weight to calculate Body Mass Index Scores.
