Matthew Mcconaughey fasts twice a year in a bid to rid himself of toxins he claims come from attention, fame and the Internet. The bohemian movie hunk reveals he started fasting when he was a teenager and took a year out between high school and college to live and work in Australia. He also became a vegetarian and abstained from having sex for a year - but neither of those practices stuck with him. Fasting, however, has become something he looks forward to. MCConaughey tells Playboy magazine, "You can get too much of things - booze, nicotine, women, your BlackBerry, attention, fame, needing people around, TV, the Internet. "Fasting is a way to pull back, go back and check on what you really need."
