A leading doctor, educator and podcast host has highlighted a straightforward habit that "may be the secret to living longer". Physician and author Dr Mark Hyman frequently shares health advice with his millions of followers across social media platforms.

On Tuesday, he discussed a Japanese dietary habit with his huge fanbase. He explained: "'Hara hachi bu' - an age-old practice from Okinawa, Japan, where people live among the longest, healthiest lives on Earth. What's their secret? Stopping when you're 80% full!"

He went on to explain that research has demonstrated eating until you're 80% full can "boost longevity, reduce chronic disease risk, and improve digestion". He continued: "This small change helps prevent overeating and supports a balanced metabolism."

Dr Hyman noted this approach "teaches us to respect our natural hunger cues - a powerful lesson in mindful eating". It also helps reduce inflammation - which overeating can trigger - and which may contribute to numerous health conditions.

The distinguished doctor has suggested people can adopt this straightforward practice themselves by consuming food slowly, as the body needs time to register fullness, and by dishing up smaller servings - pointing out you can always have seconds if genuine hunger remains. He also recommends eating with awareness and to "focus on each bite, savouring flavours to improve satisfaction".

His post emded with: "People practising 'Hara Hachi Bu' report fewer cravings, better mood stability, and even weight maintenance. Could this ancient habit be the missing link in modern health?"
