Turns out, compelling TV makes for an equally compelling before-and-after photo. That's the case with The Biggest Loser Club, the online weight-loss system of NBC's reality show The Biggest Loser. The site features photos of triumphant contestants, including celebrities like Ruben Studdard, as well as an ongoing tally of the collective pounds lost (600,000 and counting, at last check). In addition to inspiration, members receive an array of perks, including tracking tools, workout videos featuring The Biggest Loser trainers, and community support. Those who want to feel like they're on the show can even partake in weekly weigh-ins and see their place on The Biggest Loser leaderboard.
