My butt has lost volume. I eat healthy (high protein/low carb), lift heavy 4-5x week. I'm 5'0 115-130 lbs (was 117 for Sx, am currently 116). I have gone down in body fat % from working out so it doesn't look the same as it did 1 year ago. If I do gain weight too quickly (eating unhealthy) some fat has started depositing in my love handle areas ruining the contour achieved by the BBL. Do I need a second BBL or will healthy weight gain solve this issue of shrinkage?
