1000-Lb Sisters’ Tammy Slaton’s weight loss journey and surgery she’s had

Long-running TLC show 1000-Lb Sisters is back for its eighth season – and fan-favourite Tammy Slaton is completely unrecognisable from the first episode.

Starting back in 2020 off the back of Tammy and sister Amy’s popular YouTube channel, the reality show followed their difficult journey to lose weight. It’s also given fans a direct look at their personal lives, including their romantic relationships and their struggles with other family members.

Despite a difficult start for Tammy, she’s become the real success story of the show, losing around 500lbs and more recently finding love with her fiancée Andrea, after coming out as pansexual in 2021.

Slaton started off on the show weighing 608lbs, however she has said: “At my heaviest, I was 700+lbs.” Viewers watched as she struggled to crack her food addiction.

But in recent years, with the help of bariatric surgery, she’s dropped to an incredible 238lbs.

“Everybody keeps telling me I’m looking smaller than Amy,” she said on the show. “That’s kind of hard to believe.”

The sisters started the show with a combined weight of over 1,000lbs, hence the 1000-Lb Sisters title. So how did Tammy lose the weight?

How did Tammy Slaton lose weight?

Tammy and Amy had been struggling with their weight all their lives, turning to food as a comfort when their grandmother died.

However when the show started, Tammy was seen really trying to kick bad habits. She first went to rehab for food addiction, but she still struggled, leaving one centre early in 2021.

She left the centre after shedding 60lbs, which was 40lbs less than her goal. In season three, she said it had showed her what she needed to do, so she didn’t need to be there anymore.

But she soon put the weight back on – and more – and went to her heaviest weight of 725 lbs.

She was put in an induced coma because her lungs had “given up”, and three weeks later she was released from hospital.

Things started to change in 2022.

She entered another facility in Ohio and lost 180lbs, which meant she was eligible for bariatric surgery. The surgery decrease’s a patient’s food consumption. Tammy had the surgery the same year.

By the summer of 2023, after checking into another facility, she had lost almost 300lbs.

Fast forward to the season seven premiere of 1000-Lb Sisters, which aired in early 2025, Tammy shared that she was “down 500lbs”.

However, her extreme weight loss left her with some other issues which needed more surgery.

What surgeries has Tammy Slaton had?

After her successful bariatric surgery, Tammy was left with a lot of loose skin all over her body.

During an eight-hour procedure, the reality star had more than 15lbs of excess skin removed from her lower stomach, “bat wing” arms and her chin.

The surgery journey was documented on the seventh season of the show in 2025.

And it’s clear she’s enjoying her new life and showing off her results.

In a recent episode, she told a friend she’d had something done to her face too to help with her smile, as her weight had left her with a “resting b**** face”.

And it’s safe to say she’s been smiling plenty, as she has a new love in her life.

Last year, she got engaged to her partner Andrea Dalton, and their relationship is documented on season eight of the show.
