Casey King, 34, from the US state of Georgia, weighs more than 700 lb’s thanks to a lifestyle based around scoffing junk food and gaming. Casey said: “I will just eat until I am dead, probably.

“I wake up around 12, figure out something I’m going to eat immediately [then it’s] TV, video games, bed — it’s not a lot of activity.” Because of the hot weather in Georgia he prefers to skip clothes, wearing only a headset through which he uses to chat to other gamers playing online.

Casey, who is unemployed, said: “So I just sit there naked as free as can be and no-one bothers me — door’s shut, we’re good. “I’m just safe and video games are where I escape. I’m accepted in all those virtual reality worlds and the gaming world that I am in. No-one sees me. That is my outside world where I can be the Casey I want to be, but not be judged on my weight.”
