Then: Though he only lost 25 lbs. during his two weeks on the ranch, Hayes ended season 7 with a record-breaking at-home weight-loss of 151 lbs., which took him from 369 lbs. to 192 lbs.
Now: "I no longer have diabetes, gout, sleep apnea or glaucoma," says Hayes, 69, who works as a personal trainer at the Biggest Loser resort in Chicago with wife Estella, also a Biggest Loser alum. "I have tried to make food into a fuel and not a pleasure like before The Biggest Loser," he adds, citing just a 22-lb. gain since the show's end.
