The world's fattest boy who weighs 192 kilos at the age of 10 is put on a crash diet A morbidly obese ten-year-old, who is reduced to wearing just a sarong because other clothes do not fit him, has been put on a crash diet over fears he may die. Arya Permana, named the world's fattest child, weighs 192 kilograms and eats five meals a day consisting of rice, fish, beef, vegetable soup and Tempeh - a soy patty large enough to feed two adults. Arya, from West Java Province in #Indonesia, has dropped out of school as he can no longer walk and his mother Rokayah said he is 'perpetually hungry'. Arya's parents have decided to limit the amount the ten-year-old eats per day and he is now on a diet of just brown rice. This 10-year-old boy weighs 423 lbs (30 stone) and is in a race to lose weight - or risk losing his life.
