Should I lose weight before or after fat transfer to the breasts? Will my breasts deflate if I lose weight after surgery?

Thank you for your question. About 60-70% of the grafted fat survives.  At 6 months you will have a good idea of your results. Some women have a second or third procedure which continues to increase your volume safely. The best way to assess and give true advice would be an in-person exam. 

For health and safety reasons, best to be at a BMI less than 30 or within 10 pounds of your goal weight and stable at that weight for 6 months prior to surgery for optimal results.

if you are considering fat transfer to your breasts I recommend going in for an evaluation by a board-certified plastic surgeon before losing weight and attaining your goal weight. Many times it takes more than one fat transfer session to gain the results that you're  wanting to achieve. Sometimes it's not even possible to achieve the results that you want with fat transfer alone and implants may be preferable. In either case it's best to be evaluated so that you can have an in person examination to determine if you're a good candidate for either procedure. Good luck !
