I like to fast quite often (sometimes unintentionally)
How many days can an average human go without eating?
average is around a month.
If naturally our bodies are able to survive that long without food, why do we think we have to eat 3x a day. If you're competing for Powerlifting or bodybuilding I understand the importance of eating.
but many if not hardly of us are not competing.
I can go forever about this topic but all in all, give your digestive system a break and save some money.
a 1-2 days without eating isn't going to kill you.
