Trying To Eat Healthy in a College Atmosphere!

Hey everyone! I'm Katie. I'm 18 and currently working on my undergrad. It's sooo difficult to eat healthy here. My dorm always smells like pizza (not that I mind that smell ) and people are constantly ordering take-out. I always get invited to eat out or have a homemade treat. I guess it's just pretty difficult to stay on track. I mean, come on, people say that you gain the "freshman 15" pounds your first year of college. I'm trying to lose about 80 pounds. I have lost a little more than 30 already; 50 to go! I'm looking for some friends for support. Please feel free to add me, or if you have any advice, PLEASE don't hesitate to post back!
