Tammy Slaton, star of ‘1000-Lb. Sisters,’ has shown a remarkable weight loss.

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.”
