I am 5'6 and weigh between 155-160 and I'm sure my BMI is over 30. I was told by a Dr. that seen my pic that I didn't have enough fat to transfer over to get a Butt Lift. I will say that I donot have much fat around my stomach area put trust me there is some and my lower back. He said he would have to get 500cc of fat for each Gluteal/Butt. How much FAT is that? And were are the best places on your Body were you can get that FAT? Note...I have seen much,much small people than me to get a BBL.
