Dolly Martinez, My 600-Lb Life Star, Dies at 30, Family Confirms

Dolly Martinez, who appeared on Season 10 of TLC’s My 600-Lb Life, has died at age 30, with the family sharing the news in posts on social media. No cause of death has been publicly disclosed.

Martinez documented a difficult journey dealing with food addiction, mental health challenges, and severe obesity. She often spoke about how eating had become a coping mechanism, and she described health declines that left her needing oxygen and assistance with everyday tasks.

At the start of her televised journey, Martinez weighed 593 pounds. She later relocated from Fort Worth to Houston to be closer to Dr. Younan Nowzaradan in hopes of qualifying for weight loss surgery. Although she managed to lose around 40 pounds, she was not approved for the procedure.

Family tributes follow the news. Martinez’s sister, Lindsey, posted on Facebook on Saturday to share the news and remember her sister as someone with the “brightest personality.” Lindsey wrote that Dolly’s laughter and kindness could light up any room and said the family was heartbroken, expressing comfort in the belief that Dolly had been reunited with their father.

Martinez’s story was among the more challenging arcs featured in My 600-Lb Life Season 10, with the episode emphasizing both her physical health struggles and the personal instability that made sustained progress difficult. Viewers remained touched by her perseverance as cameras chronicled her ongoing treatment and efforts to turn her life around.
