Should I be at my ideal weight prior to getting Fat Transfer to my breasts?

Fat transfer means liposuction will also be performed. The targeted areas for liposuction are those that have excess fat. Once those areas have been treated, you may be perfectly happy with the contours of your body. Weight is irrelevant in persons like yourself. Focus on body contours and body composition. 

Hello and thank you for your question. Generally speaking, ideal  candidate for liposuction are those patients with their weight within 10-15 pounds of their ideal body weight. An in-person consultation and examination is needed to give you a more definitive advice. You might be ready to have liposuction and fat transfer for breast enhancement. I would seek consultation with a board-certified plastic
surgeon for a full evaluation and advice. Best,

At 5’3 and 130 lbs, your BMI is 23.  If you lose additional weight it may be more difficult to harvest the fat without leaving a contour deformity.  I recommend you consider doing the fat transfer at this time.  Not all transferred fat survives, but approximately 60% does.  Unfortunately, you have not provided photographs or told us your bra size.  However, sometimes patients would benefit from a breast lift as well as fat transfer.  The technique I recommend is The Bellesoma Method.  This will reshape your breast tissue creating upper pole fullness without implants, elevate them higher on the chest wall and more medial to increase your cleavage.  Vertical scars are avoided, nipple sensation (in 95%) and the ability to breast feed are maintained.  Best Wishes,Gary Horndeski, M.D.

Breast fat transfer is a great tool to balance breasts, improve symmetry, and gain up to one cup size in volume.  In general, 200 cc per breast is typically the upper limit of fat injection recommended by most plastic surgeons.  It is not that more cannot be injected; but on average, this has been determined to be the most that can be expected to live during one transfer.  Multiple transfers would be required for additional cc's.  In general, the abdomen and thighs are preferred donor sites but fat from other areas can be used.
Some of the retention rate will depend upon the amount of fat transferred, as smaller volumes will likely have a higher survival.  Occasionally, a patient can resorb a great deal of the fat despite optimal transfer procedures. I typically transfer from 250 cc to 400 cc or so per breast.  Thinner patients are outstanding candidates in my opinion, because the fat transferred is extremely resistant.  
Results are largely dependent upon the skill of the surgeon, his/her ability to remove fat without creating contour deformities, and your expectations. You would need a consultation with a board certified PS to determine your available fat stores.

What I would want to ask here is what is the purpose of the fat transfer?  Are you looking to gain volume in lieu of an implant?  Are you looking to contour the breast to fill in some of the upper pole hollowing?Depending on what is the answer, you may or may not be the best candidate for fat transfer to the breast.  I always advise patients that if you are interested in volume, you will be disappointed.  An implant is the only reliable way to obtain more volume in the breast.If you tell me that you have had implants before and had them removed and want to fill in the upper pole hollow that you now have, then I would tell you that fat transfer would be a good and viable option.As far as weight is concerned a few pounds up or down before surgery usually will not affect your results.  Ideally, we want our patients at the weight that they are going to maintained prior to surgery.Hope that helps.

Dear lala2020,
Generally speaking, you want to reach your goal weight before you consider a fat transfer, otherwise your results will be suboptimal if you continue to lose weight after the surgery. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

Assuming you are a good candidate for the procedure otherwise, 10 lbs is probably not going to make a significant difference in your final result.   You are at a good BMI for the procedure.  You will want to select the fat that is most resistant to weight loss for harvest.  

The problem with losing weight first is that you might not have enough fat to harvest for the fat transfer.  In fact,  some surgeons tell their patients to gain twenty pounds or so in order to be able to get more fat to use. I know that sounds idiotic but it is true. Then what happens is very little of the fat takes in the breasts and now the patient can’t lose the weight they gained.  Believe it or not this is actually  how many plastic surgeons think in their minds.  They just want to do the procedure to make the money instead of just telling their patients the truth, which is that fat transfer to the breasts is a lousy operation.  

If you wish to loose weight, please do so before the fat transfer. Even though 10 pounds of weight loss is not a large amount, it still might affect your final results. However, if you do not have much donor fat now, I would recommend considering implants.
