Richie -- once criticized for her pin-thin frame -- credits her toned, healthy physique to pro Tracy Anderson's Dance Cardio classes. "When I first came to a class, I heard I was going to be there for an hour and a half. I was like, 'Oh, I don't do that,'" the Simple Life star said in 2011. "And now I'm in there two hours a day, four days a week. It's so fun and the time flies by and the music is great."
The California native is also a fan of Pressed Juicery, which delivers its vitamin and mineral-packed concoctions to customers' homes. Of course, Richie maintains a sense of humor about the many ways in which she says healthy. "Telling people you're on a juice cleanse is a perfect way to make sure everyone is visualizing you having diarrhea," she tweeted Dec. 30.
