In this must-see live finale, the 16 contestants from this season return for a special reunion and a chance to weigh in one last time and show America how much weight they've lost since beginning their weight-loss journeys. Those who have been eliminated will compete for the $100,000 "at home" prize. Then it's the moment viewers have been waiting for, when one of the three finalists will be named this season's "Biggest Loser" and win the coveted grand prize of $250,000.
