Donna Simpson, 42, is trying to become the fattest woman on earth. Simpson, who already tips the scales at 600 lbs and wears 7XL dresses is hoping to double her weight in the next 2 years. Simpson holds a Guinness World Record for being the fattest woman to give birth at 532 pounds. It took 30 medics and a high risk cesarean section to deliver Jacqueline. To reach her current goal, Simpson is eating 12,000 calories a day and moves as little as possible. To fund her massive grocery bill, which runs upward of $3,000 a month, she runs a website where men pay to watch her eat fast food.
