The world's heaviest living woman is crediting sex with her ex-husband, in part, for her recent 98 pound weight loss.

Pauline Potter told HLN’s Dr. Drew Monday night that she didn’t plan on losing weight that way.

“It kind of just happened… and I did research and whatever and found out you can burn 500 calories," she said. "So I guess it didn’t hurt. I was kind of having fun and helping myself at the same time.”

She added, “It’s not the whole thing. I do go to my water therapy three to five times a week. I have cut out most, I can’t say all, the junk stuff. I’m replacing that with fruits and fresh vegetables.”

Potter weighed 643 pounds when Guinness World Records named her the heaviest living woman last September.

The Sacramento, California, resident met her ex-husband online in 2002 and married three years later. They split, though, in 2008.

“We still love each other," she said. "We have a life-long bond that’s not going away any time soon. If you were to ask me what was going to happen a year from now, I would have lost a good amount of weight and probably end up married again.”
