It would make sense for TLC to continue dipping into the "My 600-lb Life" pot. It's still incredibly popular, and there are no reasons for it to stop any time soon. Season 11 most recently aired from February to March 2023. If it were going to come back for Season 12, it would make sense for camera crews to film now for a release date early in 2024. The Redditor also mentioned that it was a professional camera crew as opposed to just someone with an iPhone, which lends credence to the idea this is a legitimate production. 

They continued, "My husband said he tried to walk ahead to get past the scooter and the cameraman shooed him away and directed him to walk off and around to the side." Granted, it's hard to state definitively whether it's actually "My 600-lb Life" because it's not like the person being filmed would be recognizable. The only consistent component of the show is Dr. Now, but it's safe to say in this instance, it likely would've been filming for what the person's life if like prior to starting Dr. Now's weight loss regimen. 

While it's not an official "My 600-lb Life" Season 12 confirmation, many people were nonetheless jealous that the husband may have seen filming for such a popular show. Redditor u/viridiusdynamus commented, "It's awful how jealous I am of your husband. I'd be legit starstruck if I came up on this show filming in public." In the event Season 12 materializes, people will have to be on the lookout for a woman at a grocery store to see if that scene actually made it into the show.
