Memphis, Tennessee

Memphis, Tennessee, is right behind McAllen in terms of the weight and associated health problems of its population. More than 70% of citizens live in obesity or overweight conditions, and the city came in sixth for the percentage of physically inactive adults.

Memphis has a population of 650,000, which means that roughly 500,000 of its citizens are overweight. The good news is that Memphis understands exactly what its issues are. In an effort to encourage healthy living, the city has been actively building greenways and providing support for farmers' markets. And these efforts have already helped Memphis, which was the fattest city in the US until 2012, to drop out of the top rank.
