'The Biggest Loser' (NBC)
In a TV landscape filled with Machiavellian game shows stocked with duplicitous contestants, it's a rare program indeed that encourages hard work, healthy eating, determination, and sacrifice. Even explaining this show makes you sound like a lotus-eating Zen master—or perhaps Yoda: "To win, you must lose. Every loser wins. Eat less and filled you shall be."
"The Biggest Loser" is all about shedding some serious weight, and that these contestants do. In season 7, the father-son team of Ron and Mike Morelli lost a combined 400 pounds—and they didn't even win.
Everyday dieters would have a hard time duplicating the results seen on this show: Contestants go through a weight-loss regimen so intense it makes boot camp look like a Sunday school sleepover. But if "The Biggest Loser" inspires a few viewers to exchange the Twinkies for an exercise bike, well, that's worth it, right?
