when to stop loosing?

I'm not sure if I should try to loose more wieght or not.  I'm 15 pounds more than I originally wanted, but I don't think there is any more fat to loose, and I've been maintaining for a few months.  I can't imagine that I have 15 pounds of skin, but my ps said that he thought all of the fat was gone, and I'm thinking the wieght has to be comming from somewhere.  I'm planning to get ps in Nov, but I'm thinking about trying to loose another 10 pounds before then.  My hieght to wieght ratio on the charts is a little high, but I don't look like I wiegh as much as I do.  How do you know when you are at a good wieght?  I could probably loose the wieght, but I don't know if I should.  My RYN surgeon is happy, my Nut is happy, my ps is happy.  Should I ignore the charts and be happy too?  Suggestions?

Your body will know when it's time. My surgeon's goal weight for me was 152. My personal goal weight was 144. Without trying, I lost down to 130 by 18 months post-RNY. I was steady and maintaining 130-133 when I had my PS at 22 months post-RNY. Six months after PS, I dropped down to 128.

At 152, I couldn't figure out where there was more fat for me to lose, but my body found it. Personally, I think it's better to be at a weight your body can easily maintain than to force yourself to get to a weight that you're constantly fighting to maintain. Follow the rules and let your body settle where it's comfortable.

I agree.  Find your body's natural set point. 

But, if you want to know if you have more fat then go have it tested.  There are several tests that can be done at a range of costs to determkien your body fat percentage.  A relatively low cost method would be to get a personal trainer at your gym to calculate it using calipers.  Another is with a trainer or your doctor to use a bioelectrical impedence machine (hand held or a scale).  A higher cost test but way more acurate is a water weight test (Cooper INstitute in Dallas does one).
