Tammy Slaton is earning a lot of praise for her weight loss journey.

In a series of new photos shared on Instagram, the 1,000-Lb. Sisters star, 37, appeared noticeably slimmed down. (The Kentucky native had previously documented her journey to undergo bariatric surgery on her TLC series.) And fans shared their congratulations in the comments section.

“Girl you look GREAT!” one person wrote. “Good job on your weight loss. Proud of you,” another said. Even Tammy’s doctor, Kentucky-based bariatric surgeon Eric Smith, MD, chimed in with, “You are killing it!”

Tammy has made a lot of lifestyle changes to get to this point. Here’s what she’s shared about her journey so far.

Tammy has lost over 400 pounds on her journey.

Since her series premiered in 2020, Tammy has lost over half her prior body weight. She has dropped 440 pounds, which is down from her highest weight of 725 pounds, she told People last year.

After making some major changes to her diet, undergoing bariatric surgery in July 2022, and subsequently checking into a 14-month weight loss rehab, she currently weighs 285 pounds, per People.

In a since-deleted comment, Tammy shared that she now practices eating “proteins, low carbs, no sugars, no pop, portion control,” according to Us Weekly.

Tammy regularly shows off her progress on social media, including a recent TikTok that breaks down how far she’s come.

She’s now able to walk without a walker.

At the start of her journey, Tammy had difficulty with mobility and needed to rely on a walker or wheelchair. But now, she can move around without aid, and no longer needs an oxygen tube to breathe.

“One of the big changes that I have gone through this past year is probably small to most people, but for me it was huge,” Tammy told People. “Just being able to walk without a walker or be pushed in a wheelchair, and no oxygen. I don’t even sleep with it at night anymore.”

Tammy also said that she’s now able to sit in the front seat of a regular vehicle and can fasten the seat belt without using an extender. “What seems minor to some people is giant for me,” she said.

She’s grateful for her new “quality of life.”

Tammy is happy with how her life has changed. “My quality of life has changed so much,” she said in a February TikTok. “Before I went to rehab, I was bitter, unhappy, very super suicidal, depressed, and just mean. Everybody hated me…and they still do…I had this I don’t care attitude back then. I still do, but it’s not as bad. I’m working on myself still.”

Tammy also said that she’s able to appreciate life more, and is now treating herself and others better in the process. “I have personally seen a lot of growth in how I treat people and my family,” she said. “Just my attitude and how happier I seem. I smile a lot more.”

Tammy also revealed in that video that she was able to enjoy a recent trip to Disney World. “I actually got on rides, and I rode in a hot air balloon,” she said. “I wouldn’t have been able to do any of this two years ago…I’m just giving myself a pat on the back for achieving something. Getting the weight off and living.”

She plans on getting skin removal surgery, but doesn’t have a timeline.

In another video from the same month, Tammy shared that she’s planning to get skin removal surgery at some point, but doesn’t know exactly when. “My ‘chin flap’ is not a chin flap. It’s literally excess skin and yes, it will go away when I get skin removal surgery,” she said in a February TikTok. “I cannot answer, before anybody asks, when I’m getting skin removal because I don’t know.”

She encourages kindness online.

In that same video, Tammy called out people for making mean comments about her. “Can’t I live my life without y’all judging me, making fun of me for every little freaking thing?” she said. “I can’t duet a friend without y’all thinking I’m trying to bang them. I can’t be happy and smile without y’all judging me because my teeth are missing.”

Tammy then encouraged people to be kinder to others. “You don’t understand what people are going through,” she said. “I’m very insecure. I hide it because I don’t want people to think I’m weak and I truly am weak. And calling me a turkey or talking about my face and my teeth it bothers me. I’m human.”

She added, “I just want people to realize that hating is not okay.”
