Larry Myers Jr., also known as Mr. Buttermilk Biscuits on TLC's "My 600-lb Life," has passed away at age 49 due to a heart attack, according to a family member. Myers appeared on the show weighing 940 pounds and bedridden, but underwent a second weight loss surgery in hopes of pursuing his passion for gospel singing. He gained 400 pounds after his first procedure, which led him to seek help from obesity surgeon Dr. Younan Nowzaradan. Despite setbacks, Myers remained optimistic and encouraged others to have faith. He earned his nickname by singing about buttermilk biscuits at a chicken restaurant that went viral. The Post has reached out to TLC and Myers' family for comment.
