How Much Should I Weigh if I Want 1500cc's - 2000ccs in Each Cheek Butt Augmentation Bbl Tummy Tuck Lipo Fat Grafting? (photo)

First of all, I have had many patients come in my office who tell me they want 2 liters of fat in each cheek.  But when I discuss this with them, they  have no idea how much that really is.  Two Liters is a lot of fat!  Picture a 2 liter coke bottle strapped to each cheek!  For most patients that would be a ridiculous amount of fat and make them deformed looking.  And, as Dr Shurieh mentioned, it requires a large volume of fat to be removed to come up with that much pure fat to inject.  More is not always better and is not always possible. 
I would suggest losing as much weight as possible prior to the surgery to get to a healthy weight to make your surgery safer.  It is best to have a BMI under 30 at the time of surgery to minimize your surgical risks.  A woman 5'1'' and 170 lbs has a BMI of about 32. You should always try to make surgery as safe as possible!  Also, if you plan to have the BBL and plan to lose weight, you should always lose it before the surgery.  If you lose weight after surgery, your buttocks will shrink also, thus defeating the purpose of having the BBL in the first place.

I tell my patients to be at a healthy, honest weight. If you excercise on a regular basis, eat healthy and have no medical diseases related to your weight, I would tell you that once these criteria are met you are ready for surgery, not all women are 5'1", 110 lbs, everyone has a different body type and build. Good luck and find yourself a surgeon who is experienced in BBL
