Despite Weight Loss Surgery, World's Fattest Man Dies

Andrés Moreno Sepúlveda, the world's fattest man, died on Christmas Day at the age of 38 from a heart attack in Ciudad Obregón, a city in southern Mexico.

Sepúlveda weighed as much as 980 pounds, according to the Telegraph. In October, he underwent weight loss surgery. "I start a journey that must carry me to a new phase of life, a new chapter, and I hope to a new book altogether, different and far from the prison that my own body has become," he said just before his surgery, Fox News Latino reported.

Cristiano Ronaldo, the famed soccer player, offered Sepúlveda words of encouragement after the surgery and sent him a signed shirt.
