An American woman who already weighs 273 kilos is on a mission to become the fattest woman in the world.

The Daily Mail reported that Donna Simpson, who already weighs 273 kilograms, wants to reach 450kg in just two years.

While the average woman should consume only 2,000 calories a day, the 42-year-old will need to eat up to 12,000 calories to reach her goal weight.

And despite getting around on a mobility scooter the New Jersey woman, who wears XXXXXXXL dresses, insists she is healthy, the newspaper reports.

It says Ms Simpson already holds the Guinness World Record as the world's fattest mother. When she gave birth in 2007 and needed a team of 30 medics to deliver her daughter by caesarean.

She has a weekly food bill of $750, which she funds by running a website where men pay her to watch her eat fast food, the newspaper reported.
