Becky Comet made it to the final four in season 12's 'The Biggest Loser.'
She lost 88 pounds while on the show and is now taking part in the "Fit Across America" tour.
Popcorn, Indiana is trying to change the way Americans snack, one kernel at a time -- and Comet has some helpful tips too.
"Keep track of what you eat, try to eat a healthy diet," Comet says.
"I keep a food journal every day, stay active, even just walking, just walking is a great great exercise"
Comet said her time on 'The Biggest Loser' was the hardest thing she's ever done, but also the best.
