Just keep on eating according to your diet. It sounds like you just recently got on the wagon, so in the beginning you might be eating more than you need out of habit. But the longer you eat like this with enough fat, the more your body and brain will start telling you on their own - eh, I really don't want to eat much. God - when you get to that, it's sooo relieving. You actually, seriously can get to a point when you don't overeat because you don't want to - because your stomach says, "BLAH! I'm good, dude." It took me about two or three weeks to get that feeling.
