NEW YORK -- The results are in and all bets are off -- Sin City weighs in as the metropolis with the most pounds.

Las Vegas has been named the fattest city in the United States in Men's Fitness' ninth-annual Fattest and Fittest Cities in America report. San Antonio comes in at No. 2, up ten spots from 2006, while Miami put on a few pounds to move to No. 3, followed by Mesa, Ariz., and Los Angeles.

On the other side of the scale, Albuquerque ranks as the fittest city in America, followed by Seattle, Colorado Springs, Minneapolis and Tucson.

To compile the report, Men's Fitness spent months pouring over data that make real people fit or fat, including how much residents are excising, how healthfully they eat, how much they use gym memberships, how much junk food they consume, and how much time they spend sitting in traffic. Men's Fitness also talks to mayors and city parks departments to learn about local exercise venues, programs designed to get citizens off their couches and moving, and civic leadership.

Las Vegas residents can thank the high number of fast-food restaurants -- more than any other city on the survey (except Cleveland), and extremely inactive residents. Seven out of 10 residents of Las Vegas are so sedentary that doctors say they're putting their health at risk.

The complete list of the "Fattest and Fittest Cities in America" appears in the March issue of Men's Fitness.
