One woman is making the most of a rekindled romance -- her sex life is helping her to lose weight, and a lot of it.

As reported in an interview with UK magazine Closer, Guinness World Records' Heaviest Woman in the World, Pauline Potter, has lost almost 100 pounds through marathon sex sessions with her ex-husband.

Last year, Potter, who lives in Los Angeles, was given the title after she got in touch with Guinness World Records in a bid to draw attention to her risky weight and to shame herself into dieting. But it seems to have brought forth another benefit -- as she told Closer, her ex-husband started visiting after her saw her Guiness entry, and their sex life has helped her shed a "stone" (14 pounds) a month.

“I can’t move much in bed, but I burn 500 calories a session – it’s great exercise just jiggling around,” she revealed to the publication. The couple reportedly has sex two to seven times a day.

Potter certainly isn't the first person to use the bed as a piece of exercise equipment -- certain sexual positions are known to exert more effort than others, and of course, there are always exercises to help make sex even better.

In an interview last year with The Sun in the UK, Potter noted, "My goal is to lose 200lb (14st 4lb) plus and have weight-loss surgery so I can be mobile again and not rely on anyone for help."

  • Figs

    A favorite food of ancient Greeks and Romans were figs. They're loaded with magnesium, a mineral your body needs to produce sex hormones.

  • Chocolate

    Addicting in so many ways, chocolate has always been associated with Valentine's Day. A compound in dark chocolate, phenylethylamine, releases endorphins brought on by sex.

  • Hot Chili Peppers

    They have a compound called capsaicin that gives peppers their heat and may also increase your libido.

  • Oysters

    There's an old joke that if eating oysters increased your sexual appetite: "I ate twelve but only six worked!" This food has been considered an aphrodisiac for centuries. The key mineral is zinc which is useful for testosterone production, a hormone that increases sexual desire in both men and women.

  • Asparagus

    Another food that has been considered an aphrodisiac is asparagus. The reason can be attributed to folate: a nutrient that can deter erectile dysfunction.

  • Eggs

    The thought of eggs may not be sexually stimulating, but they are a source of L-arginine, an amino acid that can reduce erectile dysfunction.

  • Beans and Lentils

    Another food that doesn't exactly conjure up warm and intimate feelings is beans. But its B vitamins and iron boost serotonin levels, the happy hormones, and sex drive.
