Chris Pratt
Chris Pratt is a Marvel Cinematic Universe superhero, but he may also have real-life superpowers, as he quickly makes losing weight seem terribly easy for him. He played the lovable Andy Dwyer on the hit TV show Parks and Recreation, but after that, he was totally buff and became an action star. In any case, we approve of the transformation – every last bit.
Christian Bale
It is not surprising, as a heavily decorated Hollywood actor, that Christian Bale would have to adhere to weight loss programs that are quite strict from time to time. In the movie The Machinist, he is celebrated for the transformation he underwent from being the starved main character to being a superhero in Batman Begins.
