I don’t know if I can go four days without eating? Is this something a normal person can do?

Surprisingly, fasting is rarely a problem for anyone. Eating is highly conditioned by routines, schedules, or stimuli such as the smell of food. Or it can often be driven by unconscious emotions, such as escaping from stress. Away from the everyday patterns and habits of our lives, it is a much different experience.

Hunger itself is usually momentary and fleeting during the first two days of a fast. Later, it often disappears altogether. The main purpose and effect of fasting is the expansion of awareness and the change of consciousness it engenders. There can be physical challenges to not eating, such as a lower level of energy, but hunger is unlikely to be one of them.
