I was told to gain a 15-20 pounds for bbl. What's the likelihood of the fat lasting for months after the surgery?

Hi.. thank you for the question... in order to give you an specific opinion clinical photos most be evaluated.. repost this with photos please.

I do not typically recommend weight gain prior to the procedure.Kenneth Hughes, MDBeverly Hills, CA.

I am not a big fan of having people gain weight for a Brazilian Butt Lift. Gaining a little bit of weight is ok (5 lbs) but gaining a significant amount of weight (15-20 lbs) is problematic. Fat is fat, so think about it. If you gain the weight and the surgeon transfers that fat to your butt, you need to keep the weight on.....or you butt will shrink.  I find that it is best to work with whatever your current (or normal) is. This means that not everyone who wants a BBL is a good candidate. Those of us who performs hundreds and hundreds of BBLs per year and understand the biology of fat cells, probably agree on this. 

Thank you for your question. The fat last after surgery. I've seen quotes between 40 to 70% fat retention after surgery. The fat that is transferred acts like normal fat ie if you gain weight the fat grows and if you loose weight the fat shrinks.usually the fat is taken from areas where you have diet resistant fat. This fat has less of a tendency to go away when your diet. If you can gain 10 pounds I think your surgeon will find it very beneficial for your surgery. I hope you find this useful. 

I do not usually tell my patients to gain weight, because often they want to lose it after surgery and inevitably the buttocks will shrink with weight loss too.

Sites of weight gain and loss are not consistent. I elect not to tell patients to gain weight. There are reputible Plasti Surgeons who will tell you to gain the weight. Bottom line, what you retain post BBL is not accurately predictable.I counsel patients that there is a forty to 80% retention rate. Per discussion with colleagues that is what we consistently see.
