I follow a woman on YouTube who had the Gastric Sleeve surgery done two months ago and she's released 67# since the surgery. She had to wait six months to get the surgery and she lost nothing during that time and then she was 288# when she started the liquid diet two weeks before the surgery and she dropped 15#, and then since the surgery she has dropped another 67#. She looked so bloated before and her face has really gone down, so I think she had a lot of water weight. You have done well, so don't worry about Spark's "one pound a week" stuff. They have to do a CYA, but really, when you follow a lot of people on YouTube like I do, they lose weight fast when they get serious about the diet and stay on it. Problem for most of them is after they get down to a reasonable weight they start back with the sugar/starches and then they regain.
