S8, E1: "The Biggest Loser" returns for season eight with a special theme of second chances. Alison Sweeney (Days of our Lives) hosts the popular series, and trainers Bob Harper and Jillian Michaels return to train 16 contestants eager to get their second chances at a new lease on life. From a mother and military wife who has always put others first, to a firefighter whose health and job are at risk because of his weight, they'’ll all come together hoping to transform their bodies, their health, and ultimately, their lives. Last season'’s heaviest contestant and fan favorite Daniel will also return for a second chance to finish the weight loss journey he started and inspire a female social worker who has taken his place as the heaviest contestant in the history of "The Biggest Loser" weighing in at 476 lbs. In the season premiere, one contestant has a health scare during the first challenge, and all of the players get a wake-up call when they meet with Dr. Huizenga to better understand all the medical conditions they'’re facing because of their extra weight. Then an emotional weigh-in is followed by an elimination, sending home the first player of the season.
