No more public weigh-ins, Jillian's drill-sergeant workouts or prize money up for grabs. What happens when the Biggest Loser cameras—and the discipline they instill—are long gone? For Gary Deckman, the runner-up in the show's first season, you keep on going. You run marathons (as he first did last January). You keep going to the gym (he does, at least five days a week). “It's a choice you make,” says Deckman, 41, who has given up eating whole pizzas for portion-controlled plates of chicken, vegetables and his favorite low-fat fish tacos (see box). Since Loser's January '05 finale, the Tarzana, Calif., semiconductor salesman has gained 14 lbs.—mostly, he says, by packing on muscle—and now weighs 170. “I no longer am prediabetic, my cholesterol and blood pressure are good, and I'm off the stomach meds I took for acid problems.” But Deckman is the first to admit that keeping it off is not always easy. When he finds himself slipping, says the married father of two, “I look at a picture of my family and say, ‘I could have a heart attack by the time I'm 42. I want to stay alive.’”
