Should I be gaining weight for breast fat transfer?

Dear Adventurous496391,
generally speaking, you want to reach your goal weight before you consider a surgery, otherwise your results will be suboptimal if you continue to lose weight after the surgery. If you are considering surgery, I would suggest you consult a board-certified plastic surgeon. Only after a thorough examination, you will get more information and recommendations.

Fat transfer to the breasts is a great option to moderately increase the size of your breasts without having any telltale signs.I don't recommend my patients to gain weight because when you lose the weight the fat will shrink.It's ok to gain weight after the procedure as the fat in your breasts will get bigger, which is what you want.

I believe you should be at your average weight. If you gain weight for a fat transfer you'll lose it after and the net result would be the same had you not gained weight.

Some surgeons recommend this but I say absolutely don’t! This is among the most ridiculous and outrageous recommendations that plastic surgeons give. If you go this route you will find out that the fat in the breasts goes away but leaves you 30 pound overweight. I’ve seen this happen to women and they are absolutely distraught. Do not take this path! It’s a terrible recommendation. In my opinion

No, do not try to gain weight for a transfer, because you will probably lose the weight and your transfer will shrink.

I don’t recommend people gain weight.
Without including pictures, we can’t assess your candidacy for the procedure. Delivering consistent quality results from both Liposuction and fat transfer is more difficult than most people realize. The number of providers who’ve truly mastered. Both of these procedures are in a small minority. I cannot emphasize enough the importance of provider selection, and to do this they have a multiple in person consultations.
An experienced plastic surgeon. It should have no difficulty showing you the before, and after pictures of at least 15 previous patients. Being shot a handful of pre-selected images, representing the best results of a providers career is insufficient to get a clear understanding of what average results look like in the hands of each provider. On top of this you need to absolutely confirm the timeframe of when after pictures were taken because early fat transfer pictures can look very impressive but do not represent final pictures. It takes six months for after pictures to represent long-term results.
Hopefully you’ve at least had an in person consultation with the person scheduled to do your procedure. Preferably if you’ve had multiple in person consultations to help select the best provider for your needs. Poorly done Liposuction can leave people permanently disfigured, and those who have insufficient skills and experience will have, poor quality outcomes when it comes to fat transfer. The number of providers who are truly excellent at this are few.
Fat transfer can increase breast size by approximately 1/2 cup. This is a typical outcome when done by somebody who knows what they’re doing. The procedure does not change breast shape in any significant way.
No one should gain weight for the purpose of having a fat, transfer procedures, and few people look and feel better after gaining weight.
If you have questions, I suggest forwarding them to your provider. If you don’t have a provider, I suggest scheduling multiple in person consultations before scheduling surgery. During each consultation, ask each provider to open up their portfolio and show you their entire collection of before and after pictures of previous patient who had very similar body and breast characteristics to your own.
Good luck,
