How to lose fat and put on lean muscle?

Hey I am 24 years old and I am trying to shed some pounds to get a decent six pack. Let me start by saying that I am not overweight and I workout just about ever day. I was an athlete in college and high school and I am not looking for advice on exercise of lifting. What I want to hear is dietary advice, what kind of diet should I eat in order to recover faster, prevent muscle breakdown and lose fat. Right now I am on a diet that has me eating smaller meals throughout the day. I make sure to always include a good amount of protein and fiber in all my meals. I also take a multivitamin in the morning and flaxseed oil to get the kind of fats that are important for the body. The kinds of foods I eat are all kinds of fruits and vegetables, especially bananas, cottage cheese, oatmeal, egg whites, wheat bread, lean turkey and ham, salmon and I drink allot of milk and I also consume 2-3 servings of whey protein. Any suggestions on how I could improve on this would be appreciated.
