Mayra Rosales once weighed more than 1,000 pounds and was facing the possibility of a death sentence, not just from obesity but for the murder of her 2-year-old nephew.
"I was dying. I don't know if you had seen pictures before you could see it in my face. I had given up in life," Rosales said. "I was alive but not living a life."
Today, things are very different for Rosales. She has lost 800 pounds through surgery and diet and still has 30 more to go. With a new body, she also has a new mindset when it comes to life and food.
"Food to me is I have to eat to live. Before it was living to eat, and now you know, it's just something normal," Rosales said.
Mayra Rosales, from Texas, said she had given up on life when she decided to protect her sister Jamie and take the blame for the death of her nephew Eliseo in 2008.
Rosales, 34, told police she had smothered the child by rolling on top of him, a claim later disproved when autopsy results revealed the boy had died from multiple injuries to his skull.
After her sister Jamie confessed to the crime and was sentenced to 15 years in prison, Mayra vowed to get healthier to take care of her sister's surviving children.
Her incredible transformation was filmed in a new documentary special for TLC, "Half-Ton Killer: Transformed," which airs on Wednesday, Dec. 4.
