Tammy Slaton’s husband gained weight when his parents died 

Caleb becomes part of the main cast in 1000-Lb. Sisters Season 4. In episode 8, he explains why he needed to go into rehab in the first place. “I’ve always been a bigger guy and that’s because I’ve always had a sweet tooth,” Caleb tells the cameras in “Forbidden Fruit.” 

“[Sweets] have always been a weakness, especially if I was stressed,” he continues. “When I was 17 years old, my mom passed away and it destroyed me for a little bit. I definitely gained a lot of weight after my mother passed away, and my father passed away in 2006.”

Caleb elaborated on how his best friend’s wife found Tammy and information about the facility on social media. “Just hearing about how well somebody’s able to do,” Caleb continued. “I said, ‘Hey, I can do this, too.” 

Like many 1000-Lb. Sisters fans, some of the other residents said Caleb’s actions gave them “stalker vibes.” But Caleb called his actions “research.” More importantly, Tammy told the cameras: “I ain’t mad.” His decision kickstarted their relationship, which resulted in their marriage.

Tammy Slaton and Caleb Willingham’s relationship timeline  

Tammy and Caleb met at the Windsor Lane Healthcare and Rehabilitation Center in Ohio. Tammy entered the rehab before she was approved for weight loss surgery in the summer of 2022. After a successful bariatric procedure, she remained there because she was still on a tracheostomy tube. 

In “Forbidden Fruit,” fans learn Caleb had been at the facility for about a year before Tammy met him. “Caleb is someone I’ve been getting to know for the past couple of weeks,” Tammy said. “Caleb’s been here almost a year and he’s just now starting to come out of his room because he had health issues.” 

After three weeks of spending time together, Caleb proposed to Tammy in the facility’s parking lot. TLC cameras captured his proposal for the episode“It’s just been a short time, but I know without a doubt you are the most beautiful, amazing, wonderful person I’ve ever known,” Caleb said. “Will you marry me?” A speechless Tammy shook her head yes. They officially tied the knot at the rehab facility on Nov. 19, 2022.
