The Japanese 80% rule, known as "Hara Hachi Bu", is a Confucian principle advising people to stop eating when they feel about 80% full, not completely stuffed, to support health and longevity. This practice encourages mindful eating, helps prevent overeating, and is linked to lower rates of illness and longer lifespans, particularly observed in Okinawan centenarians.
