Haven't read everyone's replies, but happened upon LipstickLady's and Kindle's--my WLS lifestyle and thought process seems much like theirs. The word(s) "cheat" or "cheat day" are no longer in my vocabulary. Neither is the word "diet." I will never have to be on a diet ever again. Nor is the bathroom scale the dictator of what kind of day/week/month I will have; I visit it just once a week to remind myself of my accountability.
WLS is SO MUCH about the choice being in our hands, when that piece of food goes from hand to mouth! I CHOOSE to regularly eat whole, unprocessed foods that nourish my body and keep it healthy. If/when I occasionally (once a week or less) choose a pre-planned unhealthy processed refined carb-type "food," it is merely not the wisest choice, it is not cheating because there is no reason to be guilty. And, I'm really picky now what kind of junk food those once-a-week indulgences will be.
Being free for the rest of my life from that guilt relationship with food feels so wonderful! It took me about 18 months to be totally confident in my new eating habits and really BELIEVE that I did not NEED to eat the processed fake food in carboard boxes that the food industry has so convinced all of us that we cannot live without. It certainly was not easy, by any stretch, to get my head there, but I am SO glad I have!
