I'm 5'6 and my BMI is 23.4; should I gain more weight for better results? I want a big BBL (Photo)

Hello and thank you for your question. In general, patients with a healthy/slightly overweight BMI are the best candidates for a BBL as the amount of fat that can be transferred is dependent on the amount of quality donor fat. However, please do not misinterpret this - gaining just a few pounds is not a bad/unhealthy thing but we can't necessarily choose where our body gains the fat. Some of the extra weight/fat will be in the form of visceral/internal abdominal fat which is bad for your long term health and this is also fat that we cannot safely remove with liposuction (behind the abdominal muscle fat). So too much weight/fat gain is ultimately unhealthy and some of that fat will go to places that can't be used for fat transfer anyways. Judging from your photos, liposuction of the abdomen, flanks and lower back will cinch/create a narrow waistline and will better frame the upper pole of the gluteal region. This, in combination with transferring the available quality fat to the gluteus will create a nice result. The next best step is to see a board certified plastic surgeon for an-office consultation!

You are an excellent candidate for a BBL. I would not suggest gaining any weight prior to having a BBL as the fat most likely will go internally and this will actually take away from your shape and you have sufficient fat right now to be able to use to get more fullness in your gluteal area as well as hips. You have a naturally small waist so when liposuction reveals the waist it will automatically make your butt appear fuller even before the fat is injected. I left a link to a video for you.
