Many women and men are seeking cosmetic surgery to achieve a full, curvy rear end due to the growing trend of a full, curvy rear end. Despite the dramatic results that can be achieved with gluteal implants, Brazilian butt lift surgery is often preferred by patients who prefer a more natural approach. Compared with butt implants, BBL surgery uses a patient's own fat from elsewhere in the body to increase the size and shape of the butt with less risk of infection and adverse reaction. Patients must have enough fat available to harvest and transfer to qualify for a Brazilian butt lift, so some wonder if they are too thin.

A team of expert plastic surgeons at Austin-Weston, The Center for Cosmetic Surgery, is highly knowledgeable and experienced in Northern Virginia Brazilian butt lift surgery, and can provide patients with valuable insight into the amount of fat required to achieve their ideal Brazilian butt lift results. Find out if you may be a candidate for BBL, and learn more about its benefits here.

BBLs: What Are They?

A Brazilian butt lift, also known as a BBL, involves fat transfer to the buttocks to create a rounder, shapelier rear end in men and women who are having difficulty plumping up their rear ends through diet and exercise alone. Genetics, lifestyle, weight fluctuation, aging, and others may prevent patients from achieving their ideal butt shape on their own. Austin-Weston's plastic surgeons can dramatically enhance a deflated butt without artificial implants by harvesting fat from another area of the patient's body and transferring it to the buttocks via syringe injection.

Brazilian butt lifts do not involve excision of loose skin and are not technically lifts. Traditional butt lifts may be more appropriate for patients with loose, wrinkled, sagging skin on the butt.


A variety of factors determine how much fat is used during BBL, including:

The technique and preference of the surgeon

Outcomes desired by the patient

Body proportions and anatomy of the patient

The amount of fat in the body

Fat survival rate expected

It may be sufficient to use a smaller amount of fat for patients who only wish to change the size and shape of their butts. To achieve more dramatic results, however, a larger volume of fat is needed. For a successful and satisfactory outcome, BBL patients typically require about 1000cc (1.0L) of harvested fat. When calculating how much fat to harvest and transfer initially, surgeons take into account that a small percentage of fat will die after BBL.

The award-winning plastic surgeons at Austin-Weston will thoroughly evaluate your concerns, determine how much excess fat you may need to lift your Brazilian butt, and answer all of your questions.


As opposed to considering a patient's weight when determining if he or she is a candidate for BBL surgery, surgeons usually look at the person's BMI, or body mass index, and body fat percentage. Based on the patient's anatomy and body composition, this helps clarify how much excess fat is available for harvesting.


Most patients have enough fat available on their bodies to undergo BBL surgery. A person's flanks, abdomen, or thighs are typically used to harvest fat. Some extremely thin patients with very low body fat percentages may not have enough excess fat for BBL. The use of silicone implants may be a better option for butt augmentation in these situations.

Patients often wonder whether gaining weight before BBL surgery is a good idea. Although gaining weight before a Brazilian butt lift might seem like a solution to harvest and transfer more fat, it is strongly discouraged. After BBL, patients must maintain their weight in order to preserve their results since newly transferred fat cells can shrink with subsequent weight loss. The results of BBL may be compromised or even reversed if a patient gains weight before the procedure and loses weight afterwards.
