Why stalling so much?

UPDATE: I am replying to my own post in case it helps someone else in a similar situation. After being on pureed food for a week now, my weight loss has accelerated tremendously. Maybe the clear and full liquids pre/post op were starting to impede weight loss OR maybe it's just time out from surgery and following all directions, but I am pleased to say that since my post 6 days ago I have lost 7.4 pounds in increments of .8 to as much as 2.6. I can see now that the body is going to do what it's going to do, and I just need to keep up the program like I have been. Total loss now is 38.6 (18.6 after surgery). Thanks to those of you who took the time to reply to my first post.
