It’s been proven repeatedly—a lack of sunlight and colder temperatures, both of which send more people indoors, promote weight gain. Given biology and climate, it’s only logical that cities like Philadelphia, Baltimore, and Salt Lake City are prone to piling on the pounds since they were battered with record storms and snowfall this winter. But according to our number-crunching, using real-time data, residents of Northern stalwarts like New York City and D.C. are coming out of hibernation relatively slimmer than those who basked in the more temperate climes of Miami and Dallas. Apparently, there’s more to winter weight than weather.

Both categories were weighted equally.
