Weirdly enough at my campus its just the guys that are obese. The few girls are a bit mousy but then again it's not like we have the campus culture to dress up in pencil skirts and heels like the business majors do. If I publicly shitlorded here tho I'd be a social pariah.  Was tempted last week though when a guy was talking about biking to school since the buses sometimes don't run and this fat dude asks him "but why? its only 3 minutes longer with this xyz bus!" sigh
