Eating this stuff isn't going to make me gain too much weight, is it?

I got home from school and I was/am so hungry, so I had like, three nutrigrain bars, a salmon burger patty and like, three apples. All I had all day was a bowl of oatmeal, apples, a few mini tootsie rolls and celery...probably why I was so hungry...then I came home and ate the aforemention stuff. I'm not gong to gain like, a million pounds, right? I know that's impossible but as insane as it sounds, I could use some closure.
