Should I lose weight first and then do fat grafting or opposite?

I have been extremely unimpressed with the results of fat transfer to the breasts.  Even the best results I've seen published in journals are lousy at best.  Take a look at the website of surgeons who promote this procedure and see what the results look like in two years, if you can find them.  The procedure sounds good, but the reality is quite different. Even using the Brava system, I've yet to see good results.  Don't waste your money.

I would lose the weight and then have the procedure.Kenneth Hughes, MDLos Angeles, CA...........................

You should be at a normal stable weight before fat transfer.  If you are prone to large fluctuations in weight over a short period of time (Greater Than 10-15 lbs in les than 3 months) then you should consider breast implants.  The reason for waiting for a stable weight is so that you will have the greatest chance for accurate size increase with a stable result.  

It doesn't really matter. If you lose weight first, there won't be much to transfer to the breasts. If you lose weight after the procedure, you'll lose the fat that was transfered. Neither is a good choice.
