The result of the annual analysis of US cities by Men's Fitness magazine has revealed that Houston is the fattest city in the nation for the second year running. In an analysis of the 50 largest US cities, due to be published in the February edition of the magazine, Houston boasts a low exercise and sports participation among its residents, and a high TV viewer-ship. Men's Fitness concludes: "There's not much that individuals can do about the poor air quality and even less about problematic geography, but they can turn off the tube and get out to their parks, which offer a variety of free programs for kids and adults."
