Wow! I stand corrected. Never heard of that one. Could it be because adherents don't live long enough to tell the world about it?
From Wikl:
Inedia (Latin for "
fasting") or
breatharianism is the belief that it is possible for a person to live without consuming
food. Breatharians claim that food, and in some cases
water, are not necessary for survival, and that humans can be sustained solely by
prana, the vital life force in
Hinduism. According to
Ayurveda,
sunlight is one of the main sources of
prana, and some practitioners believe that it is possible for a person to survive on sunlight alone. The terms
breatharianism or
inedia may also refer to this philosophy practiced as a
lifestyle in place of the usual
diet. Breatharianism is considered a lethal
pseudoscience by scientists and medical professionals, and several adherents of these practices have died from starvation and dehydration.
