To my fellow Extreme Weight Loss @extweightloss sis, @brandimallory you will be missed.

I’ll never forget while I was at boot camp for season 5 we watched your season and it inspired us to keep going.

Your episode was my favorite because we had so much in common from pageants to being a makeup artist and just a love of life.

When my episode aired a year later you reached out and even though we never met in person (at that moment) you and I became sisters as only a small group of us know what life was like on the show and life after the show.

We finally met in person a few years later when you came to spend time with me in Cali and it was like we’ve known each other our whole life! Girl, I enjoyed our weekend and we just stayed up for 3 days talking about everything.

We laughed we cried, we created a project together and I knew we’d be sisters for life.

You truly made an impact on this world with your zest and your passion for body positivity.

I’m blessed to have gotten to experienced you in this world.

Love you so much sis.”Following her stint on the show, Mallory persisted in her fitness journey, focusing on dance.

A candlelight vigil to commemorate her memory took place on November 12, organized by her family and friends.

The memorial service is scheduled for Sunday, November 19.
