Tammy Slaton flaunted her significant weight loss following bariatric surgery last year.

The 36-year-old shed approximately 300 pounds and showed off her trimmer figure on Instagram.

The photographs show the reality star sitting outside on a sunny day. Fans praised Slaton for her thinner appearance despite still needing oxygen tubes.

“Wow, what a great difference, keep going Tammy,” one user said, adding, “I think I speak for everyone when I say we are so proud of you.”

“I have to say, Tammy, you proved many of us wrong. Great to go, and keep it up!” said a third.

Southern Indiana Combat Production, a mixed martial arts organization, provided fans a clearer look at Slaton’s transformation in a series of images uploaded on Facebook a few days prior.

The TLC personality, who used to weigh over 700 pounds, was shown standing up without the assistance of her wheelchair for the first time in years in the photos.

Her co-star and sister, Amy Slaton, accompanied her as the couple smiled for shots while holding up a championship belt.

Tammy went to a food treatment center after struggling to attain her ideal weight to qualify for bariatric surgery.

Tammy eventually topped the scales and was authorized for the life-saving treatment during the most recent episode of the TLC series.

Flash forward to now, and the reality star’s efforts have paid off.

Tammy met her now-husband, Caleb Willingham when she was recovering from surgery.

After only three weeks of dating, the couple engaged in October 2022. They married one month later in an intimate ceremony attended by friends and family.

Fans have now expressed alarm over Willingham’s “creepy” behavior, accusing him of “controlling” and “stalking” Tammy.

TLC’s “1000-Lb. Sisters” airs Tuesdays at 9 p.m. ET.
