I am on day 11 post-op and I have lost 16 lbs since my surgery. I am 47 years old. Some days I gain some days I loose. So now I am going to weigh only once a week. I have started taking my measurements and keeping up with them. Even if the scale does not show any progress, the tape measure does. I, also take a supplement called Milk thistle. It is for the liver. In any weight loss endeavor, your liver must be functioning properly. Milk thistle seems to help a sluggish liver. I really believe that it help me loose the 32 lbs that I lost pre-op.
