A teen who once tipped the scales at 96 stone is now unrecognisable after his life-changing weight loss.
Khaled Mohsen Al Shaeri was nearing 100 stone when he was just 17 years old, before shedding an enormous 86 stone by following a strict diet and exercise plan.
Khaled, who is now 29, shared footage of himself walking around, aided by a Zimmer frame, three years after fire crews had to hoist him from the window of his home to take him to hospital.
King Abdullah, ruler of Khaled's native Saudi Arabia, had been moved by the lad's struggle with his weight and decided to rescue him from his flat.
A squad of 30 medics and civil defence troops managed to lift him out of the room using a US-bought crane.
The lad had been lying in his bed for three years when the team demolished part of the wall to hoist him out.
He was taken by medical helicopter to the King Fahd Medical City in the capital of Riyadh for treatment after the extraordinary removal.
The king had wanted to get Khalid to hospital earlier, but the rescue operation was delayed because they had to wait for a specially built bed from America.
Khaled had been living on the second floor of a building in the southern Saudi city of Jarzan but had not left his bedroom for two and a half years.
Following the king's orders, Saudi Arabia's health ministry got together with civil defence and the Saudi Red Cross to organise the evacuation.
It required part of Khaled's building to be demolished.
A forklift truck was then used to carry him to an ambulance and on to a plane, which flew him to the King Fahd Medical City in the capital Riyadh for treatment.
Saudi health minister Dr Abdullah al Rabeeah said King Abdullah had ordered the rescue as a "humanitarian gesture".
