1000-lb Sisters fans have become concerned for Tammy Slaton following the tragic news that her ex-husband has died.
Caleb Willingham was just 40 years old when he passed away, with his death being confirmed by his younger brother on Facebook on Saturday.
Tammy has paid tribute to Caleb on Instagram as she thanked him for "showing me real love and happiness".
TLC star Tammy lost an impressive 300lb (21.4 stone) after changing her life around, but some fans are worried that her grief could cause her to relapse.
Sharing their thoughts on Reddit, one person wrote: "I hope the terrible news doesn’t trigger a relapse for Tammy."
Another agreed, remarking on how far she has come on her healthy living journey: "I hope she doesn’t spiral. She’s doing amazing with her progress. Rip Caleb."
"I'm worried about Tammy right now because of this. I know they were in the process of splitting up, but I'm scared this could cause her to relapse. Grief typically does that to a person," a third fan wrote.
However, other people said Caleb's death could be the "wake up call" Tammy needed to stay on her healthy lifestyle path.
"Or be a motivating factor for her to stay the course. People grieve and honor their loved ones in different ways," one fan suggested.
Another said: "This could also be a wake up call to realize that she could also die prematurely. Hoping for healing for her during this time."
"I hope it keeps her on the right path. It could have, and almost was, her," a third person added.
Tammy and Caleb met while receiving treatment at a food rehabilitation centre. They fell in love shortly after meeting, before tying the knot at the weight loss facility.
However, they decided to call time on the relationship just months after getting married.
Reports suggested Tammy was unhappy with the fact Caleb had made little progress during his stay in rehab.
