Who's Kicked off First on 'The Biggest Loser'? (VIDEO)

Tonight's 'Biggest Loser' (Tue., 8PM ET on NBC) came down to women vs. men ... and youth vs. age. There could only be one real 'loser' this week, but we don't mean that in the shedding-pounds sense. Sixteen players started the show (after "rejected" contestants Elizabeth Ruiz and Aaron Thompkins were added back in). By the end of the night, one contestant would be eliminated, but who would it be?

[Warning: Spoiler alert.]

Things kicked off with Bob and Jillian forcing everyone to work out -- which led to the now-standard incidents of contestants crying, barfing and screaming. Following the exercise sessions, host Alison Sweeney arrived and dropped a bombshell. The players thought she'd announce a challenge, but instead she said the first weigh-in was taking place. In addition, half the contestants would be facing potential elimination ... a 'Biggest Loser' first.

The weigh-in turned into an impromptu battle of the sexes. Ada Wong was the only woman to make it over the cut-off point, while Patrick House was the only man who failed to get immunity. But Patrick was rescued by Rick, who had the power to save a single contestant.

This led to an all-female challenge where the ladies had to race each other and capture a flag. Two woman couldn't do it: Tina Elliott and Allie Ishcomer -- the oldest and youngest players in the game. When the voting took place, the 58-year-old Tina won sympathy by saying this might be her last chance to ever lose weight. So 22-year-old Allie became the first contestant voted off. Allie repeatedly said that she was "terrified" to go home. She was fearful that she might revert to her old unhealthy habits.

Allie only managed to drop 17 pounds while on the series, placing her near the bottom of the pack. And once she returned home, her greatest fears were realized, as Allie faced her greatest nemesis ... chocolate. Ms. Ishcomer called her mom, begging her to get all candy products out of the house. Unfortunately, her mom failed her. When Allie walked in the door, she saw a chocolate bar lying right in front of her. (Cue spooky music and a horror-movie close-up by the producers.)

But Allie made it through her period of temptation -- with an assist by 'Loser' Season 8 champion Danny. He told Allie that in the end, she could only rely on herself: "You have to say -- listen, I can do this ... you've got to know you can." And she did do it! When Allie reported back on her progress, she had managed to drop 60 pounds in total. Which doesn't sound so 'loser-y' to us, even if she was the first person voted off.
