I agree w/others... WHEN I'M HUNGRY, I EAT.
You may not be getting enough nutritional foods for your body. Sometimes we consider ourselves hungry if we are not "full" - which is NOT the same thing. Eating a "regular meal" (i.e. no seconds, no "huge" portions, etc.) can seem daunting when we have become too accustomed to stuffing our face. It took me quite a while to get used to the feeling of "eating less." But once I did, now I can't even imagine 2nd helpings on most days.
BTW, counting calories is really not so bad! I was opposed to it for the longest time, until I finally realized that I can eat ANYTHING I want (I just can't eat EVERYTHING I want

) and stay within my caloric range, and STILL lose weight. I have come to heavily depend on FitDay for counting my calories. Sometimes I don't (like on holiday weekends, vacation, etc) but I can still get a nice general "feel" for a basic guesstimation of how many calories I'm taking in. AND IT'S WORKING.
So I would suggest that you give calorie counting a good honest try! - and if it's not for you, don't sweat it! Keep trying different "diets" until you find one that works for you.
