The world's fattest man, Keith Martin, died at the ago of 44 of pneumonia. He weighed a staggering 445 kilogrammes at his heaviest but had undergone weight loss surgery.

According to the Daily Mail, Keith consumed 20,000 calories a day which was almost 10 times the recommended amount of calories for an adult. He ate six eggs for breakfast, and for dinner and lunch, he had pizzas, kebabs, Chinese and McDonald takeaways. For his drinks, he had six pints of coffee and two litres of fizzy drinks a day. He admitted that he knew he was killing himself by eating so much.

In 2013, the world's fattest man had a large portion of his stomach removed, which helped him lose half of his body weight. But the sad news is that in March, eight months after the surgery, he died of pneumonia.

Keith is survived by his two sisters, Sharon and Tina. Both of them cared for him for many years. Tina said that they were grieving him and that they miss him very much.

Keith's surgeon, Kesava Mannur, said that a fast-food tax must be brought in by the government. He said that unhealthy fast food must be made more expensive or else there will be lots of people like Keith.

Mannur said that whoever had a Body Mass Index of more than 30 in addition to having type 2 diabetes should be helped and offered weight-loss surgery. Mr. Mannur is in complete support of NHS guidelines which advise doctors to suggest weight loss surgery for people who suffer from type 2 diabetes and have a BMI of more than 30. This guideline by NHS allows 2 million people to be eligible for the surgery and it is reported that if all of them agree to undergo the surgery, the cost that the NHS will have to pay is 12 billion pounds.

He said that it was a shame Keith had lost his life because he had a successful gastric sleeve surgery despite the risk of his size. He added that it was unlucky that Keith had to die from pneumonia. He also said that if Keith would have still been alive, he would have lost more weight in addition to regaining his ability to walk.
