'Taboo USA': Breatharian Kirby Survives On Air And Has Only Had Seven Meals In 10 Months (VIDEO)

"Taboo USA" introduced audiences to Kirby, a breatharian. He survives on the air -- getting energy from light, wind, vibrations, he says.

“I’ve had seven meals for the last 10 months," Kirby explained on the National Geographic Channel show, noting he keeps his meals to a total of 500 calories or less. “In this consciousness, when I do eat food, it makes me feel very tired.”

Kirby has been a breatharian for five years, even though some people have died while attempting a breatharian lifestyle. But he claims he had a check-up six months ago, and is in good health. He’s convinced he can become immortal through being a breatharian and that it reverses aging.

Kirby says he wants to change the world with breatharianism, maintaining he usually only eats his daily communion -- a small morsel of bread and red wine.

"Taboo USA" airs on Tuesdays at 10 p.m. ET on the National Geographic Channel.
