"while the message of the show is inspiring, it is also unrealistic. The Biggest Loser achieves rapid transformations—contestants often drop more than 9 kg in a week—through calorie restriction, endless exercise and no small amount of dehydration that occurs behind the scenes. Ryan Benson, 38, an actor who works for a DVD distributor in Los Angeles, lost 55 kg to win the first season in January 2005 but says he regained 14.5 kg within five days simply by drinking water. Matt Hoover, 31, a motivational speaker based in Seattle, had a 7-kg rebound within a day of winning Season 2. Last season's runner-up, Kai Hibbard, 28, an aerobics instructor in Alaska who says she spent the night before her final weigh-in hopping in and out of a sauna for six hours, consumed only sugar-free Jell-O for several days and wolfed down asparagus, which is a natural diuretic. "It's amazing the things you learn in a weight-loss competition," she says."
