You Won’t Believe Which 20 Celebrities have Gained a Ton of Weight

19. Rob McElhenney

Rob McElhenney was rail skinny when he decided to pack on the pounds. The conscious effort was done because he believed his character would be funnier if he was overweight and had a big gut. So he consumed 5,.000 calories a day over 4 months to get into the shape he thought would be perfect for the role. That’s a lot of dedication, and a lot of hamburgers and junk food!
