Many people struggle with their weight loss, diet habits and personal image. Celebs are no exception. They’re constantly losing or gaining weight for various reasons, and when they don’t have a reason for looking the way they look, they are ruthlessly criticized by the media. Full-figured women with curvy bodies are labeled as fat in Hollywood, and while some eventually lose weight through the endorsement of various diets, others gain it back just to repeat the process. Losing weight in Hollywood can be compared with vanity. There’s often no need to shed 60 pounds for a part in a movie. And yet, celebs do it to gain attention, win Oscars, and prove that they’re willing to go to extreme lengths for their career. Here are 10 unrecognizable celebrity bodies.

#1 Christian Bale

Christian Bale went from the healthy, super sexy muscular Batman to a sluggish, overweight American hustler. He gained 40 lbs for his role in the famous “American Hustle” movie. In an interview, Bale mentioned that he ate everything he could get his hands on, from cheeseburgers and doughnuts to red meat and pasta. Unlike some other celebs, Bale’s transformations are not that surprising anymore. He shocked the world in 2004 when he lost over 60 lbs for his role in The Machinist. His bony, really skinny physique made him virtually unrecognizable.
