I don't honestly know why the stall broke. The only thing I did differently was something really bad -- I missed a few exercise sessions! I'm sure that's not the reason I broke the stall (in fact, maybe I would have even lost more if I had been keeping up with the exercises).

That seems to be the way I've been losing weight all along -- I stay the same for a long period of time, then suddenly a few pounds go. Guess why it happens will remain a mystery for now, but one that I hope will repeat itself!
