Prahlad Jani(wiki)
After fifteen days of observation during which he reportedly did not eat, drink or go to the toilet, all medical tests on Jani were reported as normal[16] and researchers described him as being in better health than someone half his age.[2] The doctors reported that although the amount of liquid in Jani's bladder fluctuated and that Jani appeared "able to generate urine in his bladder",[15] he did not pass urine. Based on Jani's reported levels of leptin and ghrelin, two appetite-related hormones, DRDO researchers posited that Jani may be demonstrating an extreme form of adaptation to starvation and water restriction.[17] DIPAS stated in 2010 that further studies were planned,[18][19] including investigations into how metabolic waste material is eliminated from Jani's body, from where he gets his energy for sustenance, and how he maintains his hydration status.[20]

Inedia (Latin for "fasting") or breatharianism /brɛθˈɛəriənɪzəm/ 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 when it is 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.
