I experienced a similar loss, lost 6 lbs in the first few days of phase 1 & then went up a 1/2 lb or so for a few days. By the end of the two weeks, I lost 9 lbs & then kind of stalled there for a couple weeks. After 5 weeks, I am down 15 lbs. I seem to stay at a weight & then all of a sudden drop a couple of pounds, it can be frustrating (especially if you are like me & can't help but weigh everyday) but if you stick to the plan, changes will happen
