'Tammy, I'd love to see pics of just YOU. @misshaleymichelle, we are tired of seeing your over filter face. This is Tammy's journey, not yours,' another wrote.

Tammy underwent surgery to drop the pounds at the end of 2022, kicking off her weight loss journey.

Earlier in the month, the TLC personality showed off her remarkable weight loss journey in a post to Instagram, posting a carousel of snapshots, including Tammy modeling a strapless gown, relaxing in pajamas, and lounging in a sweatshirt with her cat.

In December, Tammy revealed she weighed 285 pounds, down from her starting point of 717.

She spent 14 months at Windsor Lane Rehabilitation Center in Gibsonburg, Ohio, where she lost more than 400 pounds through treatment and bariatric surgery.

The rehab center was where she also met her late husband Caleb Willingham.

Nicknamed 'Double K', Caleb starred on the weight loss show alongside his wife as they battled their chronic obesity.

Caleb died from unknown causes at age 40 on June 30, just seven months after the couple tied the knot in November last year

Tammy Slaton has recalled the moment she learned her husband Caleb Willingham died as she opened up about her late husband in a new interview with her sister Amy Slaton

They got married with about 30 friends and family members invited to the small ceremony officiated by their home care nurse and friend, Billy.

Just months after marrying, Caleb passed away at age 40 for unknown causes.

Tammy opened up about the moment she found out that Caleb had passed away in the summer.

During an interview with People, Tammy revealed a friend of Caleb's told her over text message that her husband wasn't doing well - before he informed her just 20 minutes later that he had died.

At the time, Tammy was at her home in Kentucky and Caleb was at the Ohio rehab facility she had previously been at with him.

The TLC star was still heartbroken after his death, sharing a tribute to Instagram which read: 'RIP sweet angel, you will forever be missed and loved so much thank you Caleb for showing me real love and happiness.'
