Mississippi takes top honors once again in the fattest-state contest, according to the results of a 2007 study by the Centers for Disease Control and Prevention (CDC). The state has had the highest obesity rates every year since 2004.

While Alabama, Tennessee, West Virginia, and Louisiana are not far behind, Mississippi is the one with 30 percent of its adults tipping the scales at obese levels. Perhaps it's because the South has a lot of rural residents and black women -- both groups tend to have higher rates of obesity -- or because the typical Southern diet is rich in fatty and fried foods. Perhaps the results of this study are not entirely accurate -- it was conducted over the phone and not with actual weigh-ins.

Colorado wins for least obese state -- 19 percent of adults here are considered obese -- mostly because of its healthy and active communities. Skiing, biking, and hiking apparently keep Colorado folks moving.

Where does your state place? According to this CDC site, my state of Florida is 24.1 percent obese. Plug your state in here, choose the year '2007' and the category 'Overweight and Obesity (BMI)' and see how it compares.
