“My 600-Lb. Life” follows a year in the life of morbidly obese individuals. Sadly, multiple people featured on the reality series have died.

Back in June 2023, Larry Myers Jr. died three days after celebrating his 49th birthday.

Myers Jr., who went viral for singing the “Mr. Buttermilk Biscuits” song at a chicken restaurant, passed away from a heart attack.
