NovaQuant-Tammy Slaton's Doctor Calls Her Transformation "Unbelievable" As She Surpasses Goal Weight

Tammy Slaton is celebrating a win.

The 1000-Lb. Sisters star shared an exciting update about her weight loss journey,NovaQuant revealing in a preview for the Oct. 15 episode of the TLC show that she had surpassed the goal set by her doctor, Dr. Eric Smith.

"At my rock bottom, I was weighing about 725 pounds," Tammy explains in the clip shared by People. "The last time I saw Dr. Smith was about nine months ago and I was around 420 pounds. He told me I had to lose 100 pounds before my next appointment. I'm extremely nervous."

Tammy—who was joined at the appointment by her sister and costar Amy Slaton—stepped onto the scale, and the 38-year-old weighed in at 303.8, with Dr. Smith assuring her the weight loss was "unbelievable."

Tammy herself was also shocked by the results, celebrating the news and saying, "I surpassed Dr. Smith's goal, my goal, all the goals!"

And Dr. Smith was just as proud of Tammy, although he's not surprised she managed to reach her goal.

"Tammy has consistently demonstrated her dedication to making sustainable lifestyle changes to maximize the benefits of her surgery," he told People in an interview published Oct. 11. "I've emphasized the importance of making small, daily adjustments to ensure not only her continued progress but also her long-term success. She's truly committed to her health journey."

The next step for Tammy during her weight loss journey—which included bariatric surgery in July 2022 and a 14-month stay in a weight loss rehab facility—is the skin removal surgery. And while Dr. Smith said that generally he waits until someone has maintained their weight for three to six months, he understands that Tammy has "a significant amount of loose skin that's affecting her mobility and contributing to other health concerns."

"Given this," he explained, "it makes sense to consider surgery sooner rather than later, even though she will continue to lose weight in the future."

Throughout her journey, Tammy has been very candid about the role her mental health took on her physical body, noting that it was her battle with food addiction and depression that led to her initial weight gain.

"The Mental Battle is Real," she wrote on Instagram Sept. 23. "‘The mental aspect plays a significant role. Being depressed and having a food addiction, I often ate my feelings, taking out my emotions on food.'"

Tammy also added that she knows many of her followers are dealing with similar struggles, writing, "It's not just about food—it's about dealing with the deeper emotional challenges we face. Healing starts from the inside, and I'm here to share my journey to show that you are never alone in this fight."
