How to lose belly fat easily?

I don’t really have that much, but the body fat I do have centers around my middle. I’m trying to lose, but quite frankly I don’t really know how to properly. I’ve been cutting down on the food, eating just my three meals a day. I figure that’ll help my body use the fat reserves, right? And I have tried crunches so much but they never seem to work for me. I just need help… Anything?
