The 80 Percent Rule: Borrowing the world's longest-lived eating habit

Nadia Wren

Most people eat until the plate is empty, not until the body says enough. This is the habit behind it: stopping at four fifths full, the pause that gives your stomach time to catch up with your appetite, why the longest-lived communities built this into ordinary meals without counting a single calorie, and how to practice it at your own table without turning dinner into a math problem. Simple, steady, and easy to keep.
