At 420 pounds, Arya Permana earned the title of world’s heaviest child. The 11-year-old from Indonesia will undergo life-saving surgery to reduce his stomach to the size of a banana. Arya is already looking forward to his new, healthier life. “I’m going to play with my friends in the pool, play football and ride bicycles,” he said. His remarkable journey will air on “World’s Heaviest Child: Extraordinary People” on Channel 5 in the UK.
