Donna Simpson, 42, is attempting to nearly double her existing weight. She already holds the Guinness World Record
for being the world's fattest mom.
Giving birth to her daughter Jacqueline involved a high-risk Caesarean birth, as she needed a team of 30 medics to deliver the baby.
Recently, she has started to require a mobility scooter to go shopping, yet she still insists that she is healthy.
Ms. Simpson tries to move as little as possible, as she is only able to move roughly 20 feet before she has to rest. She also eats an enormous amount of food and subsequently wears XXXXXXXL dresses.
"I do love cakes and sweet things - doughnuts are my favourite," she told the Daily Mail
. "My favourite food is sushi, but unlike others I can sit and eat 70 big pieces of sushi in one go. I'd love to be 1,000lb. It might be hard though. Running after my daughter keeps my weight down."
Instead of discouraging her, Ms Simpson's long-term partner Philippe, 49, supports her and tells her to eat more.
"He's a real belly man, and completely supports me." Ms Simpson said. I think he'd like it if I was bigger. He said I was sexier when I was bigger, and I felt happier too."
Philippe confesses he is a fat-admirer and met Simpson on a dating site for larger people. He weighs 68kg (150 lbs).
In order for her to fulfill her goal, Donna needs to take in six times the average amount of calories each day. That's 12,000 calories per day.
So what's her grocery bill like? Simpson said it costs about $750 per week to eat, but that bill is funded by a website where men pay to watch her eat junk food.
Simpson's weight problem began at an early age when she and her brothers were given big meals by their mother, who also gave them fattening foods and treats.
At the age of nine Donna weighed 83 kg (182 lbs).
"[My mother] wouldn't let anyone say anything bad to us about our weight," Ms Simpson said. She would argue with doctors who said it was dangerous. Food was her way of showing she loved us, she wanted us to eat, and she was very protective of us."
