I've been working out with a personal trainer for the past few weeks and I love it. I don't know how much I've lost since we're doing weight in's next week. But, what I do know is my clothes are fitting looser and right now that's enough for me!

But here's my issue that I need help with, I'm a college student on a limited budget who's stuck on campus for large chunks of time. On-campus eating is what made me gain the freshman 15... plus about 30 pounds... so I'm trying my darndest to not eat on campus at all. So I'm bringing snacks. But I have no idea what healthy snacks are. My pantry has been filled with Chewy Bars and Special K Bars and Pop Tarts for so long I don't know what to replace them with. Right now I'm eating lots of fruit and carrots as snacks, occasionally the small ziplock with beef jerky.  

So I'm asking thee, Redditors of Loseit, to help me get some ideas for healthy snacks that aren't terribly expensive that will stay good stowed away in my backpack during class. Drinks and food alike, I'm open to all suggestions.
<bot>: I have terribly unhealthy snacks with me while I'm on campus. I'm trying to lose weight, but I HATE being hungry. Can you give me some healthy snack suggestions?
