So basically, areas with more reasonable climates, 50-90 degrees and low humidity, year round are in better shape than places with more extreme swings in climate (fridged winters, blistering summers). It also applies to places that have year round access to better, fresher produce, versus places where either due to weather extremes or culture, have higher meat/fat diets.
That doesn't take a rocket scientist to guess which places would be healthier.
And congratulations to Shreveport Louisiana for being the overall worst. A combination of blistery hot and humid summers, where people don't want to go out, and right in the heart of Cajun and Southern cooking, you make fat people proud.
