Rob McElhenney – Lost 70 Lbs

Rob McElhenney is best known for his role in “It’s Always Sunny in Philadelphia,” where he plays the character Ronald “Mac” McDonald. As part of his character development on the show, he had to gain 60 pounds. Then, as the role continued to develop, he lost weight again.

At the start of season 13 of the show, McElhenney shocked fans when he came out looking svelte after dropping 70 pounds. He worked hard for the results, lifting weights six days a week, running three miles daily, and cutting out alcohol, sugar, and carbs. The show aired its final episode in 2021.
