The Brooklyn, NY couple tied the knot in front of 125 guests, including fellow The Biggest Loser: Couples contestants Carla Triplett, Jerry and Estella Hayes and Adam and Stacey Capers, according to Us.
Brewer told Us she felt "absolutely beautiful" in her wedding gown.
Gurganious, a 32-year-old industrial designer, and Brewer, a 38-year-old wardrobe stylist, met three years ago at a gym and got engaged last year.
Wanting to shed some unwanted weight before their nuptials, the couple auditioned for The Biggest Loser's seventh season -- which aired earlier this year -- and were subsequently cast.
Despite Gurganious being eliminated in the third episode, he was still able to lose 140 lbs. -- going from a weight of 381 to 241 in just six months.
Brewer was had been sent home in a first week twist in which nine of the competition's eleven teams had to send a member home. However she subsequently returned to the ranch only to be ousted again --having lost 124 lbs., going from 269 lbs. to 145 lbs..
The couple plans to honeymoon in Cape Cod, MA.
"I want it to be a red two-piece," Brewer told Us about her honeymoon bathing suit. "I can't wait!"
