ME! I'm constantly trying to stay healthy on campus. The good thing about my school is that we are a commuter college so we do not have any McD's on our campus. We have one cafe that serves mostly healthy stuff (like my yummy grilled chicken salad) which is nice.
However, because of the program I'm in (education), I'm constantly running. It sucks because on the way from my college to my teaching school, there are 3 McD's. I'm hounded by temptation.
As far as exercising, I try to keep in mind that I perform at my best after exercising. So, I mostly hit those.
Losing weight sometimes takes a backseat to my school work, but I'm working on my time management so that neither has to suffer.
