How do I lose weight?

I am trying to lose about 50 lbs. this year. I don't mind working out so that's not the problem. My question is what should I eat?? I am extremely picky, I love all fruit but won't touch a vegetable. My problem is snacks, I snack all day long. What are some healthy and easy to make snacks for me to munch on while im at school or work? Thank you
