Several small meals. Your metabolism works the hardest (and isn't consuming lean mass) when you've got calories to burn. That's why people who eat WAY below their caloric needs or try to outright starve themselves often have it backfire, because your body holds onto its stores more carefully if you're not getting a sufficient, constant caloric intake.

Some people break their meals into six to eight very small meals per day (between 100-200 calories) but I HAVE to have something resembling an actual sit-down "meal" rather than a snack. So, I have reasonably small portions for my breakfast-lunch-dinner meals and then snack on healthy stuff in between. I try to eat something about every 2 or 2 1/2 hours. Based on your target caloric intake, you'll have to plan it out, but I've found that works best for me. Keeps the metabolic rate and you don't really get much of a chance to feel hungry.

Oh, and drink water too, preferably every time you eat! Works wonders. Your body has less of a chance to "crave" for things if it's already getting what it really needs (good food with needed nutrients, hydration through water, etc).
