After heavily focusing on fitness and health over the past couple of years, Khloe Kardashian shed dozens of pounds. In a recent interview with NBC, she said: "If you would have asked me five years ago if anyone would have put me in the fitness category, I would have said, 'You're out of your mind. Theres no way. I'm the fat, chubby, unhealthy sister of Kourtney and Kim." With her new show, "Revenge Body," Kardashian is helping others get into shape.
