Nope. It's altitude. I live in Colorado. The science on this altitude effect has been pretty thoroughly conducted, with potential correlating factors accounted for in multivariate regression models. Denver and its suburbs are FILLED with people who are as unhealthy and inactive as the rest of the country. Even in these places, in the poorest neighborhoods, they are less obese. I have an identical twin brother who lives in Portland, and since I've moved here I've stayed about 10-15 lbs lighter than him. It's a single, anecdotal data point, and completely unscientific, but he swears he eats healthier than me lol.
