OBESE model Susanne Eman is saying "Supersize Me" for real - in her bid to become the fattest woman ever.

The 312kg bombshell aims to reach a whopping 690kg by guzzling at least 20,000 calories a day. Susanne, 32, from Arizona, US, hopes to pass the half-way milestone of 345kg by the end of the year.

The single mum-of-two says she's already overtaken former biggest mum Donna Simpson, 43, from New Jersey, who weighs 300kg. And Susanne - who is creating a stir among fans of Super Size Big Beautiful Women (SSBBW) - plans to increase her calorie intake to keep gaining.

"I'd love to find out if it's humanly possible to reach (600kg)," she said.

"A previous record holder was 690kg, so I have to be at least that.

"My next goal is to be 345kg by the end of the year.

"At my current rate of growth, I should be 690kg by age 41 or 42."

Susanne visits the supermarket once a month with sons Gabriel, 16, and Brendin, 12, and spends up to eight hours filling six trollies.

"It's like a full day's work," said Susanne, who uses a motorised scooter, but astonishingly believes she can stay healthy.

She added: "The bigger I get, the better I feel. I feel more confident and sexy. Why shouldn't I push the limits and see how fat I can get and stay healthy?"
