The world's heaviest woman has lost a staggering 600lbs in the five years since she shot to fame as the 'Half-Ton Killer'.
She made headlines in 2008 after being accused and then found not guilty of murdering her two-year-old nephew, Eliseo, by falling on him with her own 1,000-pound body.
'I thought I was dying anyway so I decided to admit that I'd done it to protect my sister because I love her,' she concluded.
Mayra's sister Jaime was found guilty of causing injury to her child, and is currently serving a 15-year sentence.
Mayra Rosales, 32, has embarked on a grueling journey to save her own life by losing weight.
