RUBEN PERMEL, 44
After dropping 73 lbs. on his way to the top prize, the Las Vegas resident has kept up the workouts, running daily and taking a spin class twice a week. The result? Another 13 lbs. lost in 5 months—and a 34-inch waist (down from 44 inches!), which he'll proudly flaunt on the show's Sept. 7 reunion special. "Shopping is fun," he says. "I've been wearing green pants. They don't let fat people wear green pants!"
SOFIA MAGANA PEREZ, 30
Although the show's grueling training temporarily left her with an injured left foot, Perez has been able to maintain her 29-lb. weight loss by sticking to 1,200 calories a day and swimming in the ocean near her L.A. home. "I tried it last year, and they had to pull me out of the water!" she says. "Now I'm in the best shape of my life."
