That's "SSBBW" adult performer Tiffany Cushinberry. She had an active YT channel where she was going by her real name in order to reclaim her identity and separate herself from the toxic fetish feeding garbage. The channel focused on weight loss, and she claimed that she wanted to "get healthy." It looks like she's deleted or hidden all of the videos and is back to staying fat for her fetishist fans. I watched her quite a bit last year and wanted her to succeed, so I find this is really sad.
Her husband is a fat performer as well.
He used to be active on YT along with Tiffany.
