Eat until you are 80% full is a powerful, deceptively simple piece of wisdom. It’s not about deprivation, but about recalibrating your relationship with food. This single habit can fundamentally shift your health and energy levels.

Meaning
It’s the art of stopping at satisfaction, not fullness. You eat to no longer be hungry, not until you can’t eat another bite.
Explanation
Here’s the thing most people miss. There’s a critical lag time—about 15-20 minutes—between your stomach being full and your brain getting the memo. If you eat until you feel 100% full, you’ve actually overshot the runway and you’re stuffed. That 80% mark? That’s the sweet spot. It’s that moment you put the fork down and think, “I could have a little more, but I’m perfectly content.” It’s a gentle restraint that pays massive dividends. You avoid that heavy, sluggish feeling and your digestive system isn’t constantly under stress.

Origin & Factcheck
This concept was popularized in Dan Buettner’s 2008 book, “The Blue Zones,” where he documented the lifestyles of the world’s longest-lived people. It’s often attributed to an Okinawan, Japan principle called “Hara Hachi Bu,” which literally translates to “eight parts out of ten stomach full.” It’s not some new fad diet; it’s a centuries-old cultural practice.
