Researchers followed 14 of the contestants from season 8 of The Biggest Loser, including the winner, Danny Cahill, for six years after the show ended. Thirteen of the 14 regained some of the weight back, and four of those gained back what they had lost – and more.
One contestant, Erinn Egbert, who went from 263 lbs. to about 176 lbs. on the show, was able to keep off the weight and now weighs even less, between 152 lbs. and 157 lbs. But she too struggles with a slow metabolism that burns 552 fewer calories a day than is normal for someone her size.
