Lost 40 lbs.! "I was living like a frat guy," the Moneyball star said of his former diet of beer and burgers. Deciding overnight to change his habits, the 27-year-old actor told Kidd Kraddick in the Morning he "went to a nutritionist and started running instead of emotional eating." Showing off his lean new physique, the 5 ft., 7 in. actor says he even makes time to squeeze in "100 push-ups a day."
