Who was the fattest man in the world?

 Individuals like Jon Brower Minnoch, Manuel Uribe, and Keith Martin were among those who held records for extreme obesity.

Jon Brower Minnoch, from the United States, was once considered one of the heaviest people recorded in history. At his peak weight, which was estimated to be over 1,400 pounds (635 kilograms) in 1978, he faced severe health issues due to his obesity. Unfortunately, he passed away in 1983.

Manuel Uribe from Mexico gained significant attention as one of the world's heaviest individuals. At one point, he weighed over 1,230 pounds (560 kilograms). He made efforts to lose weight and was documented in his journey to improve his health. Uribe passed away in 2014.

Keith Martin, a man from the UK, was also known for extreme obesity. At one point, he reportedly weighed over 980 pounds (444 kilograms). However, like others facing extreme obesity, his weight fluctuated, and individuals in such situations often undergo significant changes due to medical interventions or weight loss efforts.

It's important to approach discussions about extreme obesity and health with empathy and understanding, considering the complex factors that contribute to such conditions and the challenges individuals face in addressing them.
