The Biggest Loser's thirteenth season eliminated Megan Stone during Tuesday night's broadcast of the NBC reality weight-loss competition's thirteenth episode.

Megan, a 21-year-old student and support staffer for an organization that assists disabled adults from Dittmer, MO, became the thirteenth contestant ousted from the competition's thirteenth season after she finished with one of the lowest weight-loss percentages at the Week 13 weigh-in, which featured the seven remaining contestants weighing-in individually as singles, and was subsequently voted off by the rest of the season's cast.

"I have come so far from the person who I was when I first arrived on the ranch. I have a lot more confidence and my athletic ability is unreal. I never imagined that I could be this athletic. There are so many things that I never realized I was capable of, but in fact, I am," Megan said following her ouster.

"I'm so proud of where I am now and I'm not done. I've still got a long way to go, but I feel like the Megan now has gotten so many tools that I can be successful."

The Biggest Loser's thirteenth thirteenth-season episode began following Kim "Kimmy" Stone's elimination after the season's previous weigh-in. The Biggest Loser host Alison Sweeney then met with all the contestants who trained with either previously new trainer Dolvett Quince, who returned to the show for his second season, or veteran trainer Bob Harper and told them they'd be competing in a Pop Challenge.

For the Pop Challenge, the contestants learned they had to load 150 boxes of food into a truck. Half of the boxes weighed 15 pounds, while the other half weighed 20 pounds. The players were required to each carry their own set of boxes onto the truck one at a time, and once all 150 got onboard, they had to pull a ring to release a flag.

Allen "Buddy" Shuh, a 42-year-old pastor from Wayne, MI, was told he was not medically cleared to compete in the challenge because of his stress fracture, and therefore, had to sit out.

Mark Cornelison, a 43-year-old youth pastor from Magnolia, TX, ended up winning the Pop Challenge and not only received a one-pound advantage on the scale but was told Newman's Own would donate 30,749 pounds of food -- which equaled one pound of groceries for every pound ever lost on The Biggest Loser -- to his hometown's local food bank.

Once the challenge concluded, Alison told the rest of the contestants that if they could finish the job, Newman's Own would donate a truck load of food to each of their hometowns. In the end, the salad dressing and pasta sauce company donated a total of $150,000 worth of groceries during the Pop Challenge.

In a season of no excuses, Bob and Dolvett attempted to convince the contestants that "exercise is boring" was not a valid excuse. As a result, Dolvett took them to participate in a Zumba-workout class and then Bob had everyone go on a bike ride.

Afterward, the contestants met with Alison in a grocery store and learned they'd be competing in the week's challenge and the winner would receive $1,000 for every pound lost on the scale over the course of the week.

Alison then explained they'd be competing in a cooking challenge where they must come up with a recipe, find all their own ingredients in seven minutes and then make the dish within 20 minutes once they all returned to the ranch. The players were told they'd be judged on taste, creativity and nutritional value of their dishes.

After the contestants cooked their dishes, they learned the judges were going to be The Biggest Loser's twelfth-season contestants Vinny Hickerson, Antone Davis and Becky Comet.

When Christine "Chris" Pickler, a self-employed 42-year-old from Middlebury, IN, presented her chicken dish to the judges, she admitted she didn't have enough time to cook the meat thoroughly and because The Biggest Loser was a weight-loss show and not a cooking show, they should have been given more time for the challenge. Antone was ultimately turned off by the fact Chris was offering excuses when everyone else had their dishes prepared and ready to taste.

However, Antone eventually apologized to Chris for offending her, and they both came to an understanding that Chris had a side to her personality that other people were seeing but she wasn't aware of herself. Although she was worried Antone's comments were negative and going to set her back in the competition, she realized she could channel it to learn more about herself and put more effort into her weight-loss journey overall.

Kim Nielsen, a 38-year-old former professional wrestler from Roswell, GA, ended up winning the challenge and was excited to hopefully win a good amount of money. She said her prize was going to be even more motivation to train hard throughout the week.

The contestants then participated in their last chance workouts.

Later on, The Biggest Loser's thirteenth-season's thirteenth elimination weigh-in commenced.

Alison explained to the contestants that the two individuals with the lowest weight-loss percentages would fall below the yellow line and face elimination, forcing the safe contestants to vote one of them out of the competition.

The players then stepped on the scale one by one to learn their fate.

Kim weighed-in first because money was on the line, and she shed seven pounds over the course of the week after dropping from 171 pounds to 164 pounds and posted a 4.09% weight-loss percentage. As a result, she won $7,000 for her weight-loss success.

Mark remained stagnant at 200 pounds, but because he had won a one-pound advantage, he posted a 0.5% weight-loss percentage. 

Buddy posted a 2.18% weight-loss percentage after losing six pounds. He dropped from 275 pounds to 269 pounds.

It was then time for Conda Britt, a 24-year-old nutrition health services technician from Rockford, MI, to weigh-in. Conda shed seven pounds after falling from 217 pounds to 210 pounds and posted a 3.23% weight-loss percentage. 

Jeremy Britt, a 22-year-old banker from Rockford, MI, dropped from 266 pounds to 260 pounds after losing six pounds total and posting a 2.26% weight-loss percentage.

Chris posted a 2.30% weight-loss percentage and shed four pounds after she fell from 174 pounds to 170 pounds. 

Megan was then the last contestant to step on the scale for the week and learned she had shed four pounds after dropping from 195 to 191 pounds and posting a 2.05% weight-loss percentage.

As a result, Mark and Megan fell below the yellow line and the other contestants had to deliberate to decide which of the two contestants would be eliminated from The Biggest Loser's thirteenth season. Meanwhile, Kim earned immunity for posting the highest weight-loss percentage of all the players.

The contestants then gathered in the voting room and revealed their votes to Alison. Jeremy, Conda and Chris all voted to oust Megan from The Biggest Loser, and three votes were enough to constitute for her elimination without having to reveal the rest of the contestants' votes.

In a post-elimination update, Megan, who started off The Biggest Loser weighing 259 pounds, said she currently weighs 189 pounds. She explained that she got back into horseback riding, racing and competing. Megan was glad she could begin doing what she loved again, as she was not able to compete prior to the show because of her weight.

In addition, Megan got engaged to her boyfriend -- who also started his own weight-loss journey at home while she was on the show -- and is planning to wed in 2013. She asked Conda to be one of her bridesmaids.
