Bernie, as the Biggest Loser of the Week from the last weigh-in, climbs Prize Mountain. He is faced with three envelopes: luxury, family, and gameplay. He's really missing his family, but of course the only option that any sane person would choose at this juncture is gameplay. Bernie opens his envelope, which says, "Give immunity to any player besides yourself." Oooh, that is tricky. Bernie seems happy with it. He's going to take a little time before deciding who will benefit from his prize.

And then it's time for a visit to good old Dr. Huizenga, the Biggest Loser physician. We are reminded of the contestants' last visit to the hospital, when they had to, like, go to the morgue and put their arms in a stomach-sized vat of fat up to the elbow. Dr. Huizenga is happy to tell everyone that he's upgraded their conditions from critical to fair. They're going to have some more tests today to find out what's going on with their bodies. Radiologist Mark Beller -- who also has his MBA...ladies -- shows Bernie a before and after scan of his body. His lungs have expanded because he's lost so much fat. And, er, he's got a lot less fat. The love handles remain, but his girlfriend needs something to hold on to, so that's cool. Bernie is pleased.

Kelly visits Dr. Jennifer Kerns. We are reminded of her fertility issues. Kelly has lost a significant enough amount of weight to have a much better chance of carrying a baby to term. I hope Trebek Jr. is paying attention! Roger meets with Dr. Said Mostafavi, the sleep apnea expert. Roger did a sleep study 48 hours earlier, and it looks like the severity of his sleep apnea has been cut in half. He's psyched.

Dr. Huizenga meets with everyone again, and says that there's still a big hurdle that remains, and it's called weight maintenance. He's brought in someone to talk to them about what it means to be an obesity survivor, and it's Dr. Jeff from season two! I act excited about that, but really I have no idea who this man is. Apparently, though, he lost a buttload of weight, and kept it off. He tells the contestants that the show saved his life. Before, he couldn't even walk up the stairs without holding onto a rail, and had a whole host of medical issues. He says that there's no cure for obesity -- everyone has to make a conscious effort to stay healthy for the rest of their lives. He notes that going home will present challenges, but with a little dedication and planning they can overcome them. The contestants all really appreciate his sage advice, and Roger in particular has been inspired to write a book about the healthy way to tailgate. Thank the Lord for turkey chili! And, one imagines, O'Douls.
