Hi Katie....I'm new here too. I just had my sleeve surgery Monday the 19th on May but I have been working at the pre-op diet for almost a year. Last June, 2013, was my first visit and the class and all the preliminary garbage. And at the end of the day they tell me you need to lose almost 50lbs and oh by the way we have you scheduled for surgery in August. So I went home and figured out the reality of what I could really lose and talked to my MD and ahe flat told me there was no way that was going to happen but do what you can. So I took this past year and changed my way of thinking mainly, but I changed my eating by visiting the Whole Foods stores and the Natural Grocery and Trader Joe stores. I knew they were not the cheapest places to shop but I started there to read my labels and see what tasted good, what I could make at home, and mostly buy at my local Safeway grocers. I had bread, low calory, I had a candy bar once or twice but I cut out anything with Aspertaime in it, diet soda, sugar free this or that. I felt better and after a struggle I lost my pre op weight, 55lbs gone. I just read something it said "One day of cheating does not make you fat just like one day of eating right does not make you skinny", I thought that was very appropriate for this journey. It's not gonna happen all at one time but it will happen over time....
Good Luck-
