Okinawa is an island quite famous for its longevity. It has a higher rate than most of the world of people living till 100+.
“Hara hachi bu!” is what the older folk of Okinawa say before they eat. It is a Confucius-inspired saying which means, “Eat till you are 80% full.”
Why? Because it takes about twenty minutes for your stomach to receive the message from your brain that you are full. For most of us, if we ate till we believed we are only 80% full, we would actually feel more full within the next twenty minutes.
So there you have it, wisdom from the Okinawans!
