I'm a 5 - 6 small meal a day person myself and was while I was losing, so it's second nature to me now.

I think it's one of the things that finally made weight loss work for me because - as Ilene says - I'm never too hungry.
I don't think there's a right or wrong answer about what to eat, since our food plans are all different, but here's what I do. Each meal is about 250 calories and always contains protein. Sometimes I have a starchy carb with the protein, like oatmeal for breakfast, and sometimes it's a veggie or fruit carb.
Here's a typical day:
7 AM (after cardio) -- 4 egg whites, 1 whole egg, 1/2 cup (dry) oatmeal
10 AM -- protein shake with some frozen peach slices blended in
1 PM -- 4 oz. chicken breast, salad, 2 T. dressing
4 PM (after weights) -- protein shake, apple
7 PM -- 5 oz. salmon, I cup green beans
But that's just what I do.

What works for you might look completely different. Perhaps try experimenting and see what fits in with your schedule and meal patterns? Figure out when your hungriest time of day is? See if you do OK just eating carbs for a snack?
