Being a loser was never so cool. When I was in Los Angeles a few weeks ago I sat down with Bob Harper, host of NBC's Biggest Loser to discuss his role as the 2010 National Spokesperson for Farm Sanctuary's Walk for Farm Animals. We discussed his recent evolution to a vegan diet, how he grew up on a cattle farm, and or course, food and nutrition! Check out the full interview, and sign up for the Walk for Farm Animals in your town! The new season of NBC's Biggest Loser premieres tonight.
