I am almost 13 years post-op. Over the years I have resumed eating all of the things I ate before surgery, and unfortunately this has been my downfall. I should have used the post-op time as a cleansing period to get the old crappy food out of my life. Now here I sit, 40 pounds regained, with all of the old cravings still firmly in place. For the years that I chose not to eat the fattening, carby, processed food, I easily maintained my weight loss and I looked and felt great. Now that my bad habits are back, so it the weights and I hate it.
All of this to say.... yes you will be able to eat most, if not all, of your old favorites. BUT, I advise you to think long and hard before you do so.
