In the first week, couple of weeks it's a fab motivator- if you're sticking to the diet 100% then the pounds drop off, sometimes even through the day. My scales got stuck in the fourth week however, so I made a conscious effort to stop. I found myself dying for the next time I could jump on the scales, and I thought if I put as much effort into working at losing weight as I did longing to get on the scales I'd be far more sucessful! Now I weigh myself on a Wednesday, just to keep tabs on my progress, and then again on Friday at my weigh in. I also only every update my ticker after my weigh in, as that way I don't get all the water-weight and other fluctuations showing, which I find quite disheartening
