No one knows how to make an entrance like a Biggest Loser contestant.
Over the past 15 seasons, contestants on the NBC reality weight-loss competition have provided some amazing and shocking moments for the live finale. And, in honor of the show’s 10 years on the air, PEOPLE has a video compilation of 10 of the most inspirational Biggest Loser success stories all in one place.
From Season 2 contestant Pete Thomas‘s 185-lb. weight loss to Danni Allen‘s season 14-winning 121-lb. weight loss, The Biggest Loser has helped more than 300 contestants lose more than 33,000 lbs., according to NBC.
But these contestants say it is not just their physical appearances that have been transformed.
The next episode of The Biggest Loser airs Thursday at 8 p.m. ET on NBC and features a visit from NFL Super Bowl champs Michael Irvin, Donald Driver and Willie McGinest.
