Some people just don't have enough fat for a BBL. In these situations, buttock implants would be a better choice. I believe that to be the case in this situation.
BBL and gaining weight
I do not usually recommend patients to gain weight. I would have to examine you in person to see what available donor sites you have, Best of luck.

I usually do not recommend weight gain for the BBL, but I would have to examine you to make a determination about the appropriateness of the BBL. On thinner patients, the exam is far more important, because a few hundred cc can make the difference between average and great results.

Thank you for your photos. It appears that you may be a good candidate for the BBL procedure. Of course, a physical exam is needed to make any recommendations. Your plastic surgeon will need to assess your donor sites to see if you have enough excess fat to transfer. The BBL procedure involves harvest fat from areas of your body where there is excess fat and injecting that fat carefully into the central zone of your buttock. In addition, it involves liposculpting the buttock to facilitate a more rounded look. The common donor sites for this procedure is your posterior waist/flanks, lateral thighs, back, waist, and anterior tummy. Please visit with a board certified plastic surgeon to learn more about your options.
