'Biggest Loser' contestant and husband drop over 150 pounds

When mother of four Lisa Rambo arrived on "The Biggest Loser" ranch, she weighed in at 246 pounds. She left the ranch 37 pounds lighter, but her journey didn't end there. Despite being voted out of the competition in week five, she went on to prove she's a "Loser" winner all the same.

"I've lost over 80 pounds so far -- six weeks left to go," Lisa revealed during a Monday morning visit to TODAY.

And her accomplishment goes beyond her own results on the scale. She inspired husband Tony to drop 70 pounds too.

"Between the two of us, we've lost a healthy adult," she boasted of their combined 150-plus-pound loss.

As for the secret to her ongoing success, Lisa credits "Loser" trainer Dolvett Quince with lighting "a fire in (her)," but ultimately chalks it all up to a simple routine.

"Who knew diet and exercise actually works?!" she said with a laugh.

See how Lisa's former fellow contestants are faring on the ranch when "The Biggest Loser" airs Monday at 8 p.m. on NBC.
