A member asked:

What are the side effects of not eating? how long can you go with out eating till it's a real problem?

A doctor has provided 1 answer

Being hungry: Biggest side effect is not feeling well and being hungry. Food is essential to life. If fast is complete it is not wise to go beyond a few days although some routinely do this. Prolonged or repeated fasting leads to a very skinny and gaunt look. Anyone who does this might be considered to have a real problem.
