Breatharian diet
Cannot really be called a diet, as it does not involve any kind of food products.
It is more of a holistic approach which claims that food and water are not necessary
for human body sustenance. An Australian lady by the name of Jasmuheen (previously
Ellen Greye) is one of the most famous personalities to practice this approach.
The concept of "Breatharianism" is based on a belief that energy
required by a human body can be derived from air and sunlight alone. "Breatharian
Diet" defies all logic and can be termed dangerous as many people have
reportedly died while attempting it.
