OLD BRIDGE (NEW JERSEY): A New Jersey woman is waging a campaign to become the world's heaviest living woman, admitting that she is as hungry for attention as she is for calorie-rich food.

Ms Donna Simpson, 42, weighs more than 272kg and aims to reach 454kg. The mother of two children, aged three and 14, models on a website called supersizedbombshells.com, where admirers and the curious can pay to watch clips of her eating greasy food or walking to the car. She has appeared in television interviews and said she welcomes media coverage.

A Guinness World Records spokesman said Ms Simpson has submitted a claim for the title of world's heaviest woman to give birth, which is still under review.

Among the heaviest women ever recorded was one who reportedly weighed 816kg and another who reportedly weighed 545kg at the time of their deaths.

Ms Simpson said she has a book offer and wants her own reality show, partly to give plus-size women more confidence.

She wears size XXXXXL clothing, which she buys mostly online, and calls herself a member of the 'fat acceptance community'. Lounging on the couch of her suburban home south of New York, she said: 'The bigger your butt is, the bigger belly you have, the sexier you are.'

Ms Simpson has found a man who appreciates her size, and they plan to marry in Hawaii this year. She said airlines are being accommodating of her needs.

Her fiancee, 49-year-old Philippe Gouamba and the father of her three-year-old daughter, said he not only finds her attractive but is also one of her biggest supporters in her quest to expand her girth. 'You look at her curves and see her full belly and generous hips,' Mr Gouamba said. 'It's very sexy.'

Ms Simpson said she gets e-mail from women who think they will never fall in love or have children because of their weight. 'I just say that's not true,' she said. 'I would love to be a voice, so that people can see a woman of size having a regular family.'

She also receives mail from those who say she is putting herself and her children at risk. She spends as much as US$750 (S$1,060) a week on groceries, suffers from Type 2 diabetes and struggles with basic tasks like cooking and showering.

But she dismisses critics who warn that her weight can lead to heart problems, aggravate her diabetes and cause pressure on her joints.

'I'm very healthy. I go to the doctor every three months,' she said.

Ms Simpson has battled weight issues all her life and was mercilessly teased. But after a friend died following complications from gastric bypass surgery, she decided to quit the dieting and the weight pills and eat what she wanted.

'I've always been comfortable with myself,' she said. 'It was just everybody else that wasn't comfortable with me.'
