Los Angeles, Nov 15 : Reality show 'Extreme Weight Loss' star Brandi Mallory has died at the age of 40. A representative for the Fulton County Medical Examiner's Office confirmed to PEOPLE that the former reality star died on November 9. The cause of death was not disclosed.

In a 2018 YouTube interview with local Atlanta journalist Kirby Carroll, the makeup artist shared how she ended up on the reality show, reports people.com. In the interview, she revealed that it was the death of one of her sorority sisters at the age of 29 that prompted her decision to lose weight. "I was literally waking up every day like... this may be my last day waking up, like, I don't know what's going to happen for me," she said. "When it's playing on your mind that I might need to do something about my weight, because I'm afraid I might die too, then you might need to pay attention to something like that." She went on to share in the interview that she saw a casting call for 'The Biggest Loser', and while she didn't get picked for that show, the producers sent details about her to 'Extreme Weight Loss'. "Literally every footstep since then has been God. I prayed over that application before I sent it off; I prayed every step of the way," she said at the time.
