I think keeping measurments is the key, when you don't have much to lose, like you, the inches might be the very thing that keeps you going
I measure every week, and if it wasn't for that, I'd be so sad everyday, as the actual pounds are coming off VERY slow. I have only lost about 6 pounds and been on this for 25 days, however I have lost a total of 13 inches. You might want to keep measuring for a couple of weeks and see for yourself what works best.
