Tammy Slaton had fans doing a double take after unveiling her jaw-dropping weight loss transformation.

The 38-year-old 1000-Lb. Sisters star — who underwent bariatric surgery in late 2022 followed by skin removal procedures — gave fans a closer look at her progress in a new TikTok photo carousel posted Tuesday.

The series began with sweet close-up shots before revealing the full impact of her 500-pound weight loss: a head-to-toe view of Tammy in a form-fitting black shapewear one-piece that showed off her dramatically slimmed-down figure.

Captioned ‘I knew the assignment,’ the post seemed to signal that Tammy is fully embracing her transformation — and delivering on it.

Looking like a fraction of her former self, she posed with her hands behind her back and a subtle smile, leaving fans stunned by her progress.

‘Absolutely loving this era of Tammy,’  one fan gushed in the comments, while another added, ‘Brought a tear to my eye. It’s been honestly so inspiring and amazing to watch your journey.’

Tammy has been incredibly candid about her journey — much of which has been documented on 1000-Lb. Sisters — and back in April, she proudly revealed she was down ‘500 pounds.’

‘When I was at my heaviest, I was 700-plus pounds,’ she shared on the TLC series. ‘Right now, I’m weighing in at 238.’

Tammy even compared her progress to that of her sister, 37-year-old Amy Slaton, who’s lost 176 pounds.

‘Everyone is telling me I look smaller than Amy,’ she said. ‘That’s kind of hard to believe. I can’t believe I did that.’

After hitting her milestone, Tammy revealed in June that she finally underwent skin removal surgery earlier this year.

‘I was just overwhelmed with excitement,’ she told People, recalling the moment she was approved.

‘I worked really hard for this, and now it’s here. I’m pretty sure it was noticeable on my face how immediately shocked and then overwhelmed with joy I was.’

Tammy spent 14 months at Windsor Lane Rehabilitation Center in Gibsonburg, Ohio, where she lost more than 400 pounds through treatment and bariatric surgery.

It was also where she met her late husband, Caleb Willingham.

Nicknamed ‘Double K,’ Caleb appeared alongside Tammy on the show as they fought to overcome their chronic obesity.

The two tied the knot in a small, intimate ceremony with around 30 guests, officiated by their home care nurse.

Tragically, just months after their wedding, Caleb died at age 40. His cause of death was never made public.

Tammy spoke about the heartbreaking moment she found out, revealing that a friend of Caleb’s first messaged her saying things weren’t looking good — and then delivered the devastating news just 20 minutes later.

‘I was sitting in the fetal position,’ she recalled to People.

‘I got a text message from his friend up there and the text said, “Caleb’s not doing good. They’re in there working on him.” Twenty minutes later, he texted me back and said he was gone.’

In a previous season of 1000-Lb. Sisters, Tammy also admitted their relationship had changed in his final months, saying they ‘felt like roommates’ before his passing.
