Brazilian Butt Lift: Should You Gain Weight?

In a typical Brazilian Butt Lift (BBL) procedure, the average desired volume of fat transfer is between 500cc to 1000cc per buttock cheek. In order to attain these transfer volumes, we would have to harvest approximately 3 to 4 Liters of fat. However, most patients do not have 4 Liters of fat to transfer. One factor in a successful buttocks fat transfer is harvesting ALL of your body fat via full body liposuction. I see many patients disgruntled with their previous BBL surgery, especially after they find out that their surgeon did not utilize all of their available fat.

You have to understand that by gaining weight, your fat cells don’t increase in number but rather swell in size.

During your Brazilian Butt Lift procedure, we use a liposuction cannula to harvest the fat cells. Unfortunately, as the fat cells get larger, they are more vulnerable to injury when suctioned through the small openings of the cannulas.

Fat cell membranes are fragile and essentially break off, becoming nonviable. Smaller fat cells have a better chance of getting through the cannula holes and tubing without mechanically being damaged by this trauma. What makes your Brazilian Butt Lift procedure successful is ensuring fat cell survival during the harvesting and transfer process.


By gaining weight prior to BBL surgery, you are fighting your body’s “set point”. This is the body’s comfort weight, i.e. the weight that your body wants to be at based on your lifestyle. A rapid weight gain for the purpose of temporarily increasing your fat volume would eventually result in the body’s desire to return to its lower comfort weight. This means that you will lose the initially gained volume once your body returns to its comfortable weight. In summary, if you gain weight to transfer fat to your buttocks, you’ll eventually go back to your comfort weight. You will lose even more of the volume of fat that was transferred during the Brazilian Butt Lift than if you had just stayed at your comfort weight.

Following your initial consultation, Dr. Mowlavi will be able to calculate the amount of available fat that you have to transfer to your buttocks so that you don’t have to worry about losing any volume post-surgery.
