Breatharianism and Inedia

Info source: http://en.wikipedia.org/wiki/Breatharianism

Breatharianism is a concept, in which believers claim food and possibly water are not necessary, and that humans can be sustained solely by prana (the vital life force in Hinduism), or, according to some, by the energy in sunlight (according to Ayurveda, sunlight is one of the main sources of prana). The terms breatharianism or inedia may also refer to this philosophy practiced as a lifestyle in place of the usual diet.

Inedia (Latin: "fasting") is the alleged ability to live without food. The word was first used to describe a fast-based lifestyle within Catholic tradition, which holds that certain saints were able to survive for extended periods of time without food or drink other than the Eucharist.[citation needed]
