so are you moving onto mash stage?
You may find at this time you will put on more - the body is taking in very minimal calories and stalls are common because it's holding on to the food and reserves in your body, this will normally change when you get on to normal foods.
Weight loss isn't dramatic with a band, it's 1-2lb average a week, but also stalls and gains are common. I've just done 7 days milk/water and 7 days bland mashed foods due to a defill and put on 4lb.
Don't give up, stick to the guidelines and hang in there. At the moment you're recovering from surgery and body is healing too
