Colorado is the least obese state in the country, according to a new government survey released Thursday.
Only about 19 percent of the people taking part in a random telephone survey last year by the Centers for Disease Control and Prevention were in that category.
Dr. William Dietz, who heads CDC's nutrition, physical activity and obesity division, says Colorado is a state with a reputation for exercise, and an elevation that causes the body to labor a bit more.
Meantime, Mississippi, Alabama and Tennessee lead the nation in obesity. More than 30 percent of adults in each of the states tipped the scales enough to ensure the South remains the nation's fattest region.
The 2007 findings are similar to results from the three previous years.
