A: We get a lot of questions like these. Even viewers who enjoy watching contestants drop pound after pound on "The Biggest Loser" are sometimes skeptical about how that's actually possible.
I talked to Dr. Michael Dansinger, a consultant on "The Biggest Loser 2" and a physician at Tufts New England Medical Center, who explained that the "people in the show are in a fantasy, unrealistic environment where everything is optimized for weight loss." He notes that everything from working with a trainer to having absolutely nothing else to do makes it possible for contestants to completely reconfigure their diet and exercise routine.
Dansinger says that "50 to 60 percent of [contestants’] weight-loss success comes from dietary change." They're used to consuming around 3000 calories a day, but on the show consume about 1500 calories a day. As he says, "few people are really in a position to cut their calories by 1500 a day, but that's what these people are able to do." He says there's "nothing controversial" about the diet, nor are the contestants given pills or other shortcuts.
The other 40 to 50 percent of weight loss comes from the three hours of exercise the contestants do every day: an hour of strength training and two hours of cardio. That helps them burn an additional 1200 to 1500 calories, Dansinger says. "It's hard to do by yourself, but on the show it's easy to do," he said. "When people allow themselves to be put in that kind of environment ... when you pull out all the barriers to weight loss, that's when the weight loss can come very quickly."
While Dansinger consulted daily with the producers over the phone and via e.mail during production about diets, fitness, and other issues, there was another physician on set with the show who was responsible for patient care and monitoring contestants' physical fitness. That doctor also had the ability to veto challenges or pull a contestant from a challenge if he felt that it was unsafe. —A.D.
