Hi Jenny, I went through the exact same thing, I was down about 17 lbs. just about 2 weeks post op then nothing! I was told your body just has to get used to the new routine. Since you deprived it of so much, It is holding on to everything you are putting into it. Once it "catches on" you will start losing. Just remember, your using food as fuel now, not for hunger so try to eat about 6 meals a day. If you hardly eat your body will go into starvation mode & store everything as fat, thinking you won't be giving it anymore. Another thing is that us "lightweights" sometimes lose slower than the people who have more to lose. Hang in there, it will come off...your body just has to get used to the new you!
