(CNN) — The next cycle of the NBC hit weight loss competition “The Biggest Loser” debuts Tuesday with the show’s third couples edition.

As trainers Jillian Michaels and Bob Harper get ready to take on what is being hyped as the show’s biggest season, CNN revisited past winners Bill Germanakos (season four), Ali Vincent (season five) and Helen Phillips (season seven) to follow up on their lives since their big wins.

Not surprisingly, they’re all working to share their gift of health with others who struggle with weight issues.

But what exactly are they doing now? Have they kept the weight off? And have their lives really changed for the better? Here are their stories:

Bill Germanakos competed against his twin brother, Jim, on the fourth season of the show in 2007. Bill’s mantra on the show was: “To become half the man, so that he could be twice the man.” He literally almost reached that goal. Germanakos, who started the competition at 334 pounds, dropped 164 pounds, for a 49 percent weight loss and a weight of 170 pounds.

CNN: What do you weigh now?

Germanakos: Today, I stand at approximately 210 pounds, which is the weight that I arrived at about two months after winning the competition and a weight that my physician and I feel is a healthy, comfortable and (most importantly) sustainable weight for me. This is the weight that I have maintained for approximately two years now, which simply means that “The Biggest Loser” helped me to accomplish and maintain a weight loss of approximately 125 pounds.
