The World’s Heaviest Child who once weighed an astonishing 423lbs (191.9kg) says he wants to have surgery to remove his excess skin after losing more than half his body weight.

The 13-year-old Indonesian teenager, Arya Permana, gained the title thanks to his diet of instant noodles, fizzy drinks and deep-fried chicken.

At just ten years old the youngster was barely able to walk, had to be homeschooled and was forced to bathe in an outdoor pond.

Thankfully a surgeon has offered to remove the excess skin from Arya’s chest and arms after his upcoming exams, Daily Mail reports.

Arya’s size peaked when he was just ten years old and weighed the same as six boys his age.

His father, Ade Somantri, admitted that they compounded to is weight challenges by giving in to the teenagers demands for fattening foods.

Arya’s father said: “Back in the day since Arya was five-years-old and already getting big I can say, “Yes I spoiled him”.

“If he wanted to eat or drink sweet food and drinks we just gave it, if he wanted instant noodles, we just cooked [it] for him…”

With his size putting his life at risk, Arya reportedly became the youngest person ever to undergo a gastric-sleeve operation.

The procedure – along with a strict diet of grilled fish and vegetables – helped the teenager lose 234lbs (106kg), with him now weighing 189lbs (85.8kg).

Arya would eat five meals a day, with two large plates per sitting.

Arya’s parents were initially reluctant to let their son go under the knife but realised they were putting his life at risk by stopping him having the surgery.

Arya had the five-hour bariatric surgery at the Omni Hospital in Jakarta.

Just one month later, he had lost nearly 70lbs and the weight continued to drop off.

But Arya was not thrilled with the lifestyle changes that came with his transformation.

“At first Arya was very annoyed and upset because he loved eating but after the gastric bypass surgery, automatically if he ate a lot he will vomit,’ his father said.

Since the gastric bypass, just seven spoons of food is enough to fill Arya up. Meanwhile, the pond Arya bathes in has been overtaken by plants.
