well, for what it's worth...the same thing happened to me until i started to work out a bit. That made me lose a few more pounds and started to firm me up a bit. Also - for me...I was kind of cheating on the nuts, eating more than the allowed....so I tried to cut them out...or at least be really strict about them...not eating them every day.
And the ricotta cremes...instead of making them all part skim, i started making them mostly fat free with a little part skim in there...just to cut the fat since I was eating them every day.
It's hard though. I lost about 9 or 10 pounds in the first 2 weeks...and then nothng for weeks. I didnt gain, but i didn't lose. I thinkthe working out did it for me. But it was awfully discouraging.
Also - if you didn't have that much to lose, those last 5 or so pounds can be a real doozy.
I don't know if that helps at all....but don't get discouraged!
