The real preparation of breatharianism differs in some ways. Some breatharians claim to never eat but they drink, some says they never eat or drink and others admit that they eat occasionally to connect to the culture, but claimed that only on rare occasions for cultural reasons and not for physical nourishment.
Breatharianism is within human potential, but for most of the time it remains quiescent. Those who feel drawn to living on light nourishment can activate this potential, but this is not an easy task, it needs patience and beliefs.
