I think this sort of surgery throws up all sorts of emotional issues as time goes on. Many of us have been overweight since children and there's a lot of baggage that goes with that I think.
It sounds as though you were doing grand with food too sunny. I am struggling to get to 400 cal a day at the moment, but I'm not going to worry about it until I am on solid food again.
I have just done all my measurements today, waist, hips, chest, calf, thigh, neck and arms. I'm going to track the progress in the measurements as I think that is far more telling the numbers on the scale.
