It appears that mighty Thor has gone on a dramatic weight loss program that he has nicknamed "Lost at Sea" in an Instagram post revealing his new look. 

For his new role in a movie about the real-life whaling ship Essex that was attacked by a whale in 1820, inspiring the book Moby Dick. He had to go on an extreme diet, along with the rest of the cast, to look like a shipwrecked first mate.
