The "Starving Diet" is really not for the faint-hearted. Chris Hemsworth has now officially joined the ranks of actors and actresses who have made drastic changes in order to condition themselves properly for a new role. Hemsworth, who would be playing a marooned seafarer in the movie "In The Heart Of The Sea," posted this picture of himself looking alarmingly thin and sporting a tangled mane of hair. We could also see a severe tan and even a deprive-look that Thor would never have on his face.

Chris tried to make light of his situation by captioning this picture: "Just tried a new diet/training program called "Lost At Sea". Wouldn't recommend it.. #IntheHeartoftheSea "

He still looks pretty buff and we wouldn't want him to go any further like what Jared Leto did for Dallas Buyers Club. Someone feed me right away after filming!
