Dolly Martinez, a participant on the reality show 'My 600-Lb. Life', has passed away at the age of 30, as confirmed by her sister Lindsey Cooper on Facebook. Lindsey described Dolly as a person with a vibrant personality who brought joy to those around her. The family is devastated by the loss but finds solace in the belief that Dolly is now reunited with their father. Dolly's struggles with food addiction and mental health were documented in her episode, where she began weighing 593 pounds and required oxygen for daily activities. Although she relocated from Fort Worth to Houston, Texas, to be closer to her doctor and lost approximately 40 pounds, she ultimately was not approved for weight loss surgery during her time on the show. Dolly is survived by her child and ex-husband Philip.
