Ditto all of the above. Let me share with you how I'm thinking about it as I get close to stabalization.
Before this diet, I never really thought much about my total day or total week intake. I took each meal as it's own and would decide about treats or no treats, eat healthy or have something tasty. They were never really connected together - which meant, I probably treated myself way too much.
Now after paying such close attention to what i've been eating for the past 7 months, in maintenance, I'll see the bigger picture. Pizza for dinner means healthy breakfast and lunch that day or a couple treats in a row means get back to basics for the rest of my meals that week. I'm not really thinking of it in terms of what i'll never eat again, because I don't see how there's anything i could never eat. But what it does mean is to pay attention to the whole day or the whole week and make sure you that of the 21 meals a week, 14 or so are really good for me so I have the flexibility for the other 7 (or whatever percentage it turns out to be). Now I'm used to thinking like this so I won't accidentally go like 10 meals that aren't very balanced.
I hope that answers your question. Moderation is indeed key, and trust me when I say that i'm planning a very decadent dinner (with dessert) for my maintenance celebration meal... which i'll followup with a healthy breakfast and lunch
