I've been on 810 for 10 days now and the scales refuse to move. Last week the scales went down and are now back up and have stalled. I've been using exactly the amount of portions stated in the book, so really not sure. I know people have said that it takes time for the body to adjust, but most people don't stall on 810 it usually 1000. My CDC has said it's impossible not to lose on 810 but I'm beginning to think maybe I'm just one of the unlucky ones. I'm trying to be patient, but really don't know what to do. I've been stuck at the same weight for nearly 2 weeks. Anyone else stall on 810?
