At one point in his life, Arya Permana was so large he could barely move from his bed.

But the 12-year-old boy from West Java — who was last year dubbed the world’s fattest child by the Indonesian World Records Museum — has now been dethroned after he lost a whopping 182 pounds. At his peak, Permana weighed over 420 pounds.

Permana went through a gastric procedure in April 2017 to shed weight, and now has a doctor and dietitian monitoring his progress and keeping him on a strict diet.

“They prevent me from consuming sweet food and drinks, particularly soft drinks,” Permana told the Australia Broadcasting Company.

“They ask me to eat more fruits and do exercise regularly.”

He said his weight has dropped dramatically since the surgery, saying it made his stomach smaller and made him less hungry. “Now even six spoons (of food) already makes me full.”

Permana is now able to go outside and play sport with his friends — something he never would have thought possible a year ago.

As he got older, he rapidly grew more obese, with his parents concerned that he could eat five large meals a day — enough to feed two adults for the whole day.The boy weighed nearly 7 pounds when he was born — an average size for a newborn — and remained an average size until the age of two, when his weight soared.

In an earlier interview with The Sun, Permana’s parents Rokayah and Ade Somantri said they were thrilled he could finally lead a normal life.

Rokayah said: “We are very happy to see him leading a healthy life. He is very active and in good health.”

“His sleep is sound and there is no more worry of respiratory problems.”

“He can also walk and play without complaining of shortness of breath.”

But they did worry that he might require another operation, noting he can’t eat more than a few spoons of rice without throwing up.

“He walks and runs for 1.25 miles a day but he might require another round of surgery this year.”
