The Heart of Dixie might need some cardio workouts – Alabama is home to three of the most obese cities in the United States.

Credit and financial site WalletHub is out with an analysis, ranking 100 U.S. metro areas across 19 indicators of weight-related problems.

To come up with the list, the site looked at three indicators of weight, health and fitness.

For example, the analysis examined the number of overweight and obese people in each area, the share of the population with diabetes, high cholesterol and high blood pressure, and the share engaging in physical activity.

In all, 19 metrics were examined, with points awarded in each category. The highest scoring cities ranked higher.

Surveys suggest more than 40% of Americans are overweight, a statistic with massive consequences of a different kind, in terms of health care costs, productivity and quality of life.

McAllen, Texas tipped the scales at the top of the list, followed by Little Rock, Ark., and Jackson, Miss.

Mobile came in fourth nationally, with Birmingham sitting at 10th. Huntsville huffed its way to finishing at 32.

Mobile got its high rank due to a second place finish in the list of cities with high medical consequences of obesity. Birmingham, according to the list, needs to work on its physical fitness grades.

And lest Huntsville get too smug, it could also improve its exercise scores, according to the ranking.

At the bottom of the list – Honolulu, Hawaii, which seems mildly unfair.
