Well, I'm kinda new at this whole banding thing, but when i was working out a lot back in the day I followed this book called BODY FOR LIFE. You'd eat all these small healthy meals throughout the week and once a week you had this one day where you could eat whatever you wanted. It was pretty insane, and my friend he would do that and on that day he would eat crazy stuff like one time he ate a dozen Krispy kreme donuts and he dropped weight on that day!!!!!
He said it was awesome to be able to trick his body, but i don't remember the specifics of why your body would do that. I'm gonna have to find my book, and get back to you, but i totally believe you on that.
But i think you are doing a good job, keep watching your intake, and slowly but surely you'll get to where you want to be. Good luck, and I'm going to see if i can find that book and post it up for you.
