My bariatric clinic gives everyone in my lap-band program homework. One of our homework assignments this month was to go on a 3 day trial liquid diet. I thought that those three days would be really tough for me, but they weren't. I drank protein shakes for breakfast and lunch and ate sugar-free jello, Greek yogurt, tomato soup and drank FF milk throughout the day. I lost 7 pounds in those 3 days and I was consuming about 1200 calories a day. I have never experienced such rapid weight loss. That was over two weeks ago and I haven't regained any of that weight. I'm actually looking forward to my 10 day pre-sugery liquid diet. Maybe I'll drop 10 pounds in those 10 days!
