48 y/o interested in BBL and breast fat transfer - do I have enough fat for both procedures? (photos)

Based on your pictures, you are an excellent candidate for a "mommy makeover" and have sufficient fat for your desired procedures. While the procedure is personalized to each patient, a "mommy makeover" often addresses volume loss in the buttock and breasts regions as well as a protruding abdomen by combining fat grafting to the buttocks and lateral hips, a tummy tuck with or without muscle plication, and a breast augmentation with implants or fat grafting.
Additionally, you may benefit from having strategic liposuction to your flanks, middle/lower back and bra roll regions for an improved silhouette. An in person or virtual consultation with a MommyMakeover specialist will provide you an accurate recommendation and pricing.

The amount of fat that is available is only one factor. Your goals as well as your selection of your surgeon are important as well. Most patients get an immense benefit with maximal liposuction of the abdomen, sides, and back to obtain the smallest waist possible and then maximal fat transfer to the buttocks and hips. The goal is to transfer fat from areas where you find it displeasing to areas in which you would like more 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 ccs. 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. 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.

Based on these photos, it looks like you will have sufficient amount of fat to be used for augmentation/shaping of breasts and buttocks/hips. In person consultation with a plastic surgeon with expertise in fat transfer and liposuction, is recommended. Good luck.
