Things got emotional early on as we picked up from the previous week. Kristin was happy to still be on the Ranch, but Tara was upset that her teammate Laura had gone home. I needed to talk with Tara because she knew I told Mike to send Laura home (she needed to recover from the worst injury in Biggest Loser history!). I let Tara know it was time to focus on HER. The rest of the week played out just as emotionally. Here's what I mean.

Quiz Time: Alison met the contestants in a room set up like a game show studio. Rosemary Ellis, editor-in-chief of Good Housekeeping magazine, was there to help Alison lead a series of fitness and food trivia questions for the six remaining players. They guessed the number of servings in a "personal" pizza, the healthiest oil, the leanest type of meat, and the increased amount of steps that people take if they use a pedometer. As the two with the most correct answers, Kristin and Mike continued to a bonus round, where they had to guess the amount of calories in a fried fish sandwich with tartar sauce. Mike guessed 635 calories, just shy of the correct amount of 640. For being the lucky winner, he'd get a trip to New York and a tour of the Good Housekeeping Research Institute, where the magazine tests all sorts of consumer goods.

Caged In: This week's challenge was not for those fearful of heights. The players were suspended in their own cages 45 feet above the ground, grasping ropes that held up their body weight. The idea was to stay steady and keep holding on. If they let go of the rope, their cage dropped a few feet, then they were lowered to the ground and were out of the game. Mike was the first out because he couldn't stand being up so high. In the end, only Helen and Tara still hung on, and of course challenge rock star Tara managed to outlast Helen. For winning, she got a choice: $10,000 or a one-pound advantage at the weigh-in. She had until the weigh-in to decide.

Video Food Diary: Bob had his team film what they ate throughout one day so that they could show off what they had learned at the Ranch so far. Unfortunately, the players still had some lessons to learn because Bob definitely saw some major flaws in the meals they created. Some of the meals were way too low in calories to fuel what the contestants were doing in their workouts. Plus, there was hardly any protein included. Bob talked over the video, showing his team their mistakes so they could grow from the experience.

Open Communication: As my team suffered through some killer two-minute sprints as part of their last-chance beatings, Mike got frustrated and punched the treadmill. He needed to finally let go of the inner "fat kid" mentality that he was a failure. Mike and I started talking, and it quickly became clear that he had some anger issues and needed to talk to his dad immediately — he'd been feeling that anger and bottling it up for a long time. He was upset because Ron had let Mike and his brother Max follow in his footsteps and become overweight. I'm glad that Mike let it all out and that Ron now knows things need to change permanently.

Weighing In: Taking a risk and betting on herself, Tara chose to take the $10,000 prize from the Challenge instead of the one-pound advantage. And it ended up being a good bet because she lost 5 pounds this week! Ron lost 4 pounds, putting him at 298. Finally the 54-year-old dad was below 300 pounds, a place he hadn't been since his early teen years. Mike lost an awesome 8 pounds and was the biggest loser of the week. Kristin, on the other hand, gained a pound, and Helen lost only one, so they were both below the yellow line and up for elimination. In the elimination room, it came down to a tie with the votes, and since Kristin was the one with the lowest percentage of weight loss, she was the one to go.

Back at home, Kristin is an inspiration to her friends and family. In fact, two months after leaving the Ranch, she gave a motivational speech about her time on The Biggest Loser, saying that change is possible for anyone willing to try. She's lost a total of 132 pounds since the start of her weight-loss journey.
