A woman who spent years deliberately putting on put on weight in her quest to become the heaviest woman in the world has now lost a staggering 238lbs after splitting from her feeder boyfriend - ultimately saving her life.

Morbidly obese Patty Sanchez, 51, went from 721lbs to 476lbs, after finally breaking free from a viscous cycle of constant eating, which was encouraged by her ex-boyfriend and online fans.

At one point Patty, who lives in Reno, Nevada, wanted to be the heaviest woman in the world - consuming 13,000 calories per day for several years.
