Chris Pratt
Chris Pratt is a superhero in the Marvel Cinematic Universe, but he may also have superpowers in real life since he makes losing weight quickly seem awfully easy for him. On the hit TV show Parks and Recreation, he played the lovable Andy Dwyer, but after that, he went completely buff and has become an action star. In any case, we approve of the transformation – every last bit.
Christian Bale
As a heavily decorated Hollywood actor, it is not a surprise that Christian Bale would have to adhere to weight loss programs which are pretty strict from time to time. He is celebrated for the transformation he underwent from being the starved main character in the movie The Machinist to being a superhero in Batman Begins.
