2 Weeks before my surgery I was also put on a liquid diet. It was the HMR which was 500 caleries per day. nothing else, no jello, no nothing. I lost 10 pounds by surgery. one warning i gained 5 pounds the day after surgery from just liquid and jello but now 8 days after I lost 3 addition lbs from my surgery date. And my band did not even get a fill yet. So hang in there. Trick is eat right, do not nash, and excercise.
