Gaining weight for skinny BBL? how can I quickly gain weight if my metabolism is fast & I have a hard time gaining?

Gaining weight is often counterproductive. If you gain weight that is fat, some of the fat will likely be associated with the buttocks.  In almost every case, I do not recommend weight gain prior to a BBL. I think it is better to maintain your stable weight.

Great question!  Although gaining weight may help with volume in the short term, most patients end up loosing the weight they gained as they don't like how their face or arms look after the weight gain.  Once you loose weight, you will also loose the volume from the grafted areas so in the end, there's really no point in gaining the weight unless you plan on maintaining the higher weight.  If you are looking for other options, please see a board certified plastic surgeon.Best of luck and hope this information helps!- Dr. Roger Tsai  @DrRogerTsaiBoard Certified Plastic Surgeon

I recommend seeing a plastic surgeon for consultation to see if you have enough fat for a BBL.  Gaining weight may not be a great option if you plan to lose the weight after surgery.  Weight loss may cause the buttock augmentation to shrink.  

Dear pskinnybbl,
most plastic surgeons won't recommend you to gain weight prior to surgery because you will lose transferred fat once you start losing weight after surgery. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

Hello dear!!
Thanks for the question and provided information as well. 
Unfortunately, without pictures, it is very difficult to give you a proper answer. l recommend you to make an appointment with a board certified plastic surgeon to talk about your goals and anything you need to know.
Good luck :)

I do not recommend gaining the weight quickly in order to harvest more fat for a BBL.  Unless you plan on maintaining the new weight gain your BBL results will not last.  The grafted fat will shrink if you lose weight after the procedure.  Some medications have a weight gain as an undesired side effect. Potentially these medications could be used off label for weight gain though I do not recommend this.  Certain foods eaten in excess also contributes to obesity . In particular foods with high fat high carbohydrate combinations like donuts tend to do the job.  If you have not done so already I would recommend having a few in person consultations with local board-certified plastic surgeons who specialize in this procedure.  Some people simply don't have enough fat to do a proper BBL and for those people it may be better to simply not have the procedure.  Others may have enough fat to get a partial BBL result and this may justify doing the procedure.  For patients with low BMI's and insufficient amounts of subcutaneous fat who want a BBL a commitment must be made to liposuction almost the entire body.  This generally includes full torso Full abdomen 360, fullback armpits and potentially lower back), Arms and inner thighs and knees.  Sometimes less areas are treated depending on age individuals that distribution and desires.  I appreciate the predicament you're in. Sometimes being thin is not ideal but it is generally much better than being obese. Count your blessings, Mats Hagstrom MD
