Lisa Rambo may have been voted off of The Biggest Loser
, but she is thriving on her weight loss journey at home – and so is her family.
"I've come home and I've had my family and we've done this together," Rambo told reporters Tuesday, the morning after her elimination aired on NBC. "We're doing this together and we're strong. It's amazing."
Rambo, 37, was unanimously eliminated
by her team, who cited her "support system" as their determining factor to send her back to her family in Houlton, Wis.
"I got off the airplane and me and my husband went for a three-mile run," said Rambo. "I was smaller than when I left home but he had lost 40 lbs. He said, 'Hey, Skinny.' And I said, 'Hey, Skinny,' right back."
Rambo has now lost more than 80 lbs. and her husband has lost more than 70 lbs. The couple has gotten their four children involved as well.
"We went to our kitchen and literally threw everything that wasn't good away – bags of food," Rambo said. "And my kids didn't scream or complain. They like the walnuts, apricots, apples and cheese sticks. Your kids won't freak out if you change your kitchen."
As a high school special education assistant, Rambo is hoping her new, healthy lifestyle will rub off on more than just her own children.
"[It's about] making healthier choices, getting our students moving and finding things they love – like bowling and swimming," she explained. "Working out doesn't have to be a chore."
But it is a challenge. Rambo is balancing her full-time job with at least two workouts every day. Making things easier is the childcare support from her family, friends and husband.
"Just two or three days home from the Ranch, I was picking up laundry and my husband took it out of my hand. He looked at me and said, 'You are still on this 'me mission.' We want you to stay focused and finish this as strong as you started.' I'm a lucky lady," Rambo said.
As she continues to fight for the at-home prize of $100,000, Rambo is maintaining a diet of "about 1,200" calories a day of mainly fruits, vegetables and lean proteins.
"I have my eye on the prize," says Rambo, who now weighs less than 170 lbs. "But I've really already won at home."
