So what recommends this diet book? The numbers. Host of NBC's The Biggest Loser, which draws nine million viewers per episode, Harper boasts 350,000 Facebook friends, 160,000 Twitter followers, and 80,000 unique visitors per month at mytrainerbob.com; more than 850,000 viewers have seen his YouTube videos. And his face will be appearing on 130 million Quaker Oats boxes in the months to come. Harper condenses the usual recipes, menus, tips, and techniques into 20 (dare I say) bite-sized pieces. In demand, no matter how many diet books there are.[Page 92]. (c) Copyright 2011. Library Journals LLC, a wholly owned subsidiary of Media Source, Inc. No redistribution permitted.
