Although not stressed by Dr. Sears, my impression is that contestants exercise a huge amount.
Go to the Sears link above and you’ll learn that all contestants are paid to participate. In researching my Conquer Diabetes and Prediabetes book, I learned that the actual Biggest Loser wins $250,000 (USD). Also, “The Biggest Loser” is an international phenomenon with multiple countries hosting their own versions, with different pay-off amounts. A former Biggest Loser, Ali Vincent, lives in my part of the world and still has some celebrity status.
This TV show demonstrates that the calories in/calories out theory of body weight still applies. Including the fact that massive exercise can help significantly with weight loss. In real-world situations, exercise probably contributes only a small degree to loss of excess weight. The major take-home point of the show, for me, is that you can indeed make food and physical activity choices that determine your weight.I know losing 50 to 10o pounds of fat (25–45 kg) and keeping it off for a couple years is hard; most folks can’t do it. Do you think you’d be more successful if I gave you $250,ooo for your success?
