Dr. Huizenga is one of the first people the Biggest Loser contestants meet. He gives them a thorough physical to assess how healthy, or in most cases unhealthy, they are. He makes the determination whether or not they can compete on the show. In cases like Biggest Loser 6’s Jerry, there are strict limitations on what they can and can’t do on the ranch. Many contestants, like season 5’s Bernie Salazar, credit Dr. Huizenga with helping them regain their health and lives. Here Bernie and Dr. Huizenga visit immediately following the Biggest Loser: Families finale.
