Gracie McGraw, the daughter of country music superstars Tim McGraw and Faith Hill, is opening up about what she calls one of the biggest mistakes of her life.

The 29-year-old actress revealed that she used Ozempic for roughly three years before deciding to stop — and now says the popular weight-loss medication came with devastating personal consequences.

“I think it was probably one of the worst things I’ve ever done for myself, looking back,” Gracie wrote in a series of Instagram Stories posted Monday.

Although she initially celebrated the dramatic weight loss, Gracie said the injections eventually reignited an old eating disorder, warped the way she viewed her body and left her believing her internal system had been permanently changed.

At first, however, the results felt like a dream come true.

“At that time, I thought it was the best decision I ever made because I finally lost weight and got skinny,” she wrote.

Gracie said her slimmer appearance quickly brought her more attention and even more opportunities — a painful reality for someone who claims she had been mocked over her body for most of her life.

“I’ve been called fat and ugly my entire life, whether that had been from magazines or the internet, constantly saying I must have different genes than my sisters and parents because I was the ‘fat’ one and didn’t have the looks that my family has,” she wrote.

Gracie is the oldest of Tim McGraw and Faith Hill’s three daughters. Her sisters, Maggie and Audrey, are 27 and 24.

Growing up in one of country music’s most glamorous families only intensified the comparisons.

Hill, a five-time Grammy winner, became a major beauty icon during the 1990s and was once declared the “most beautiful woman in country music.” Her husband, Tim McGraw, has repeatedly appeared on lists celebrating Hollywood and country music’s most attractive men.

The couple married in 1996 and went on to become one of Nashville’s most famous power couples.

Gracie said she originally began taking the appetite-suppressing medication after being diagnosed with polyendocrine metabolic ovarian syndrome, previously known as polycystic ovarian syndrome, or PCOS.

The hormonal condition can cause weight gain, infertility, irregular or heavy menstrual cycles, acne, abnormal hair growth, skin discoloration and an increased risk of heart problems, according to the Cleveland Clinic.

Gracie acknowledged that the GLP-1 medication helped control some of her symptoms. But she said it also awakened dangerous thoughts and habits she believed she had left behind.

“I realized, ‘Holy c–p, I have been feeding into my eating disorder this whole time under the guise of this miracle shot,’” she wrote.

Gracie admitted she became “way too skinny” while taking Ozempic and claimed the experience had a lasting effect on her body.

“My internal system is forever changed since taking the meds,” she wrote.

After stopping the injections, Gracie said she began gaining weight again — just as Hollywood appeared to be racing back toward an ultra-thin beauty standard.

“Now as everyone is getting smaller and smaller, I am gaining my weight back and seeing how much losing all of that weight actually affected me and my views of myself,” she wrote.

Gracie said her own experience inspired her to speak out about what she sees as the entertainment industry’s increasingly troubling “skinny culture.”

A growing number of stars have faced public concern over their rapidly shrinking appearances, particularly as GLP-1 medications have exploded in popularity.

“The discourse we are seeing right now on certain bodies is not out of body shaming; it is out of concern,” Gracie wrote.

She added that she felt “triggered by the lack of help [for] someone who is actively dying in front of the world.”

“It’s extremely difficult to see, especially since seeing little kids online saying they wished they looked like that,” she wrote.

Gracie did not identify the person she was referring to.

However, Ariana Grande’s increasingly thin appearance has generated widespread concern among fans and fellow celebrities throughout 2025 and 2026.

The scrutiny intensified after Grande released the music video for her single “Petal” on July 31. Images of the 33-year-old Wicked star triggered a wave of worried reactions online.

Grande’s representative later announced that the Grammy winner planned to step away from public life after completing her tour.

For Gracie, the painful lesson was not simply about losing weight. It was about realizing how quickly praise, attention and outside approval can disguise something deeply unhealthy.

What once felt like a miracle, she said, ultimately left her struggling to rebuild her relationship with her body.
