She was once a competitive gymnast but years later, the weight had piled on and Georgeanna Johnson was a shapely 315 pounds when she first weighed in on ABC's Extreme Weight Loss.
The wife of Church on the Move pastor, Scott Johnson, put her weight gain down to the amount of time she invested in being a wife and mother.
"I think I got so caught up in being mum that I forgot who Georgeanna was, she told Tulsa World.
"I don't know the specific thing that happened that made me give up on taking care of myself.
"I think I never made myself a priority."
But she clearly dug her heels in to bring down the pounds, having shed an impressive 165lbs.
Johnson, of Tulsa, Oklahoma, looked thrilled and gorgeous in a flattering red dress as her incredible weight loss was revealed on Tuesday night's episode of the hit ABC show.
The pounds she lost over the course of the year amounted to more than half of her original body weight and returned her to the same weight as when she was a teenager.
"I lost like an entire me," she said.
