I gained around 15 as a freshmen. I wasn't working out and was eating pretty much nothing but boxed mac-n-cheese, spaghetti with lots of bread and butter, and pizza's I could bring home from my job at Domino's, and beer. I also was not working out. Once I started working out I lost it all. My GF gained about 20, and a recent google of her shows she kept on going since then... Mooooo!
