I'm 5'7'',140 lbs (usually 135 lbs) with body fat% between 12% to 14%. I have tried to gain weight up to 150lbs last year, but still has no subcutaneous fat when examined. So I have to reverse back to 135 lbs when ps did my Tummy tuck and BBL last year. He only got 70 cc fat. 1. Should I continue to gain weight for BBL? I'm afraid I'll gain all visceral fat. 2. Can I do butt implant/BBL compo? My wish butt is Jessica Biel's and love to get to 36-25-40 (current 36- 26 -38).
