From 610 kg to 63 kg: How world's heaviest man, Khalid Shaari, lost 542 kg weight

We often encounter remarkable weight loss stories. However, this story stands out as an extraordinary example of a significant change. Khalid bin Mohsen Shaari, once the heaviest man alive, has undergone a remarkable transformation, losing 542 kilograms through the intervention of Saudi Arabia's former King Abdullah. Shaari, who was bedridden for over three years and weighed 610 kilograms, received extensive medical care at no cost thanks to the king's intervention.

In 2013, Shaari's condition caught the attention of King Abdullah, prompting him to organize a comprehensive medical plan. The plan involved a team of 30 medical professionals dedicated to handling Shaari's case. Utilizing a forklift and a specially designed bed, Shaari was transported from his home in Jazan to King Fahd Medical City in Riyadh for complete treatment.

His treatment plan included gastric bypass surgery, a tailored diet, and a rigorous exercise regimen. Intensive care and extensive physiotherapy in the initial six months helped Shaari lose nearly half of his body weight. By 2023, his weight had reduced to 63.5 kilograms. However, multiple surgeries were necessary to remove the excess skin that resulted from his significant weight loss.


Shaari's journey from being entirely dependent on friends and family to regaining his mobility was nothing short of extraordinary. Now, he is affectionately known as "the smiling man," a nickname given by the medical staff who supported him throughout his journey.

Shaari’s story stands as a testament to the impact of dedicated medical care and the incredible transformation that can occur with proper intervention and support.
