Breatharian' Khai Ho maintains that he is able to survive for months at a time on little more than air and sunlight.
The 38-year-old, who ironically works as a pizza delivery man, claims that his unusual way of life has made him feel healthier, despite the fact that he apparently eats next to nothing at all.
Breatharianism is a very controversial practice because the idea of surviving without food or water is patently ridiculous - as humans we need both of these things or we will die.
Attempting it is dangerous and there is no scientific evidence to suggest that it can work. Many people have died attempting it while doctors and scientists alike have dismissed it as pseudoscience.
This begs the question therefore - what is the truth behind Khai's claims ?
"I have never really felt hunger and never took much interest in food as a child," he said. "My mum was always worried about me and still is. I could never really embrace that state of consciousness that I was after, until about four years ago when it became more serious."
"I was maybe eating every three or four days at first, but now I can go months without food or water and even then, only have a mint or so to take away any bitter taste in my mouth."
"It's an amazing feeling, I'm fully conscious of my mind and I've never felt so great."
"I'm fully aware of my surroundings. People think I'm crazy but incredible at the same time."
