Fans agree that 1000-lb Sisters season 3 is the most exciting entry in the Slaton family's franchise yet, but Tammy Slaton recently shared that 1000-lb Sisters season 4 is yet to be confirmed. Although Tammy and her siblings' stories are far from over, the TLC network hasn't decided whether or not viewers will get another helping of the Slaton clan's fitness expedition. From TLC's history of announcing upcoming seasons to Tammy's potential inability to return to the series, here's why fans think 1000-lb Sisters hasn't been renewed for season 4 yet.

For better and for worse, 1000-lb Sisters season 3 has been the most climactic chapter of Tammy and Amy Slaton's health quest yet. In season 1, Amy and Tammy were both well within the grips of their debilitating food addictions, and in 1000-lb Sisters season 3, the Slaton siblings are reaping what they sowed in as Amy's arduous weight loss work has allowed her to start a family of her own. Conversely, Tammy's ongoing apathetic approach to her weight has placed the star in a precarious position in season 3 as she faces more health risks than ever before. Although 1000-lb Sisters season 3's momentum requires a follow-up entry, the series hasn't been renewed for season 4 just yet.

Tammy's health and relationships with her siblings are at a turning point in season 3 and fans agree that 1000-lb Sisters season 4 is poised to capture a crucial moment in the Slaton family's trajectory. From Amy preparing for the birth of her second child to Chris living his life post-bariatric surgery to Tammy leading her life after getting her tracheotomy, there are plenty of riveting episodes left in store for the family of reality stars. Regrettably, it's unclear whether or not TLC will renew 1000-lb Sisters season 4. Even though season 3 is almost over, the network has kept their lips sealed on the fate of the Slaton sisters' series. A Reddit user shared that Tammy commented on 1000-lb Sisters' future, recalling, "[Tammy] mentioned that there's no renewal for their contract yet... she doesn't know if she would want to do another season."

While many fans are concerned that 1000-lb Sisters hasn't been renewed for season 4 yet, others aren't as worried about the series' fate. One reason why TLC hasn't announced season 4 yet could be that the network is slow to renew 1000-lb Sisters. A viewer noted, "They were late announcing renewal of the other seasons too." Although 1000-lb Sisters season 2 ended last January, TLC didn't confirm season 3 until March 2021. This means that fans shouldn't be surprised if there's no news about 1000-lb Sisters getting renewed for a couple of months. Another theory is that TLC is waiting to see how Tammy's health holds up. Since suffering from carbon dioxide poisoning, Tammy's lived in a nursing facility, which could impact her filming capability. A cynical fan theorized that 1000-lb Sisters hasn't been renewed for season 4 yet because "They want to make sure [Tammy's] still alive first."

Unfortunately for impatient fans, the future of Amy and Tammy Slaton's excursions in 1000-lb Sisters is still up in the air. From the TLC network's habit of taking their time before making any announcements to Tammy's delicate current health predicament, there are several factors that explain why 1000-lb Sisters hasn't been renewed yet. Hopefully, 1000-lb Sisters season 3 won't be the end of Amy and Tammy's complicated weight loss journeys.
