just thought I would add my two cents, which is a lot like Teri's two.

I have never counted calories. At first, because I am concentrating on changing the way I eat, and then after about five days or so, I don't need to. My appetite is so completely obliterated that I have to make myself eat three meals a day!

I never counted calories until after I stopped eating this way (the first time).

Now that I am starting again, I will once again, not count calories.

My feelings, based on my own experience and those that I know were sticking to the plan, are this: if you're doing it right, you won't be hungry all the time and you won't need to count calories. Not that you don't have to...you won't need to.
