Will weight gain affect fat transfer?

Had fat transfer to cheeks and around laugh lines with facelift and am now noticing fullness in my upper cheeks and midface that wasn't there a few months ago, also notice that my mouth looks pulled down at the corners and kind of wider. This is similar to my appearance during the worst of the swelling while I was healing. I did gain about 15 pounds in the past 2 months, would this be the reason for the change in fullness? Or could it be inflammation/swelling? Will weight loss ruin face? tx
