Larry Myers Jr. -- who appeared on Season 10 of "My 600-Lb. Life" -- has died in Texas.
Family spokesperson Sonya Hines-Hall tells TMZ ... Larry -- nicknamed "Mr. Buttermilk Biscuits" on the TLC show -- died from a heart attack at his Houston home last week while mourning the death of a friend.
Larry's relatives announced his passing on social media ... and set up a GoFundMe page to pay for his funeral costs. They also remembered Larry as a talented gospel singer who didn't let his struggle with weight dim "his drive to show love and kindness to all he met."
When Larry appeared on the TLC show in an episode that aired in January 2022, he was bedbound and tipped the scale at a whopping 940 pounds.
Larry underwent weight-loss surgery back in the day, but he gained 400 pounds after the procedure ... leading to his appearance on 'My 600-lb Life."
He was 48.
RIP
