Dukan Diet

Channing Tatum lost 15lbs in one day.The Foxcatcher actor underwent a gruelling regime to portray wrestler Mark Schultz in the movie and admits he and co-star Mark Ruffalo resorted to extreme lengths to get into the shape they needed to be in.He said: "I dropped 15lbs in a day. You have a ton of water in your skin and stomach and Ruff and I figured out how much weight we could lose in the gym."I was not feeling very well after that."

The 34-year-old hunk admires his character from the film because wrestling takes much more discipline than acting.He explained: "To win Olympic gold, you train from childhood. Theres no just jumping in, saying, Im really gifted. Its a day-in, day-out obsession."Channing never formally studied acting so views his work on movie sets as his training.The former stripper told heat magazine: "I had on the job training. Each film has been a school term. Its an expensive education."

Though the Magic Mike actor is enjoying a strong career, he still regrets roles he lost out on.He said "Ive not cried about losing a part but I really, really wanted John Carter. Its one of those that got away."
