It's clear some humans don't need to eat. Their body and mind adapt life energy aka prana. They believe in it and after a (long?) process they manage to do without food. Some do not drink either. They are healthy, active. So what if it's just an idea in our head we do need to eat?
The first people, cavemen didn't eat so much, didn't eat daily and most likely had a interest (liberated). Today people eat, eat and eat and are more unhealthy than ever. Let's assume there's no healthcare, no doctors, no medication. How many of the present population would still be alive?
Who knows after the great reset or in 50, 100, 150 years people no longer need to eat and we are like the aliens we see on the telly?
