I am 2.5 weeks out and i only lost 11lbs..nothing has come off in a week. I came home 6lbs heavier then when i went in and that took about 4 days to come off then i lost any extra water weight my body was holding onto. 2nd week i lost 3 and nothing since. I was told the same thing your body just went through something traumatic so it takes time for your body to catch up but it will. Don't get too frustrated. Also take your measurements if you haven't already...you would be surprised if the scale isn't moving but you are losing inches.
My PCP told me your body just went through something traumatic & you won't see results the 1st week. She said trust the process-it WILL come off. I lost 3 lbs the 1st week-my surgery was the 12th & I also thought it was strange but what she said makes sense.
