About The Biggest Loser Season 15, Episode 9 :

This week, the contestants take a pop quiz about obesity in the workplace after meeting host Alison Sweeney in a diner. The location proves significant since that's where the losing team will be working all week while still trying to eat healthy and exercise with much busier schedules. While the losing team stays busy waitressing, cleaning up, doing dishes and squeezing in workouts, they still find time to bring "treats" from their day job back to the ranch to tempt other players. Meanwhile, one trainer works closely with his contestant to determine what has been holding him back from bigger weight loss numbers, and another tries to help one player's family member get started on the path to a healthier lifestyle. Then it's time for another contestant to head home after a weigh-in that yields surprising results.
