Harvard Professor: “I Tried Every Diet. This Is By Far The Worst.” - Daniel Lieberman
"He did a deep dive onto these blue zones and found out that only 18% of the people in these blue zones actually had birth certificates. So we don't even know who these people are. They just self-report their age."
Daniel Lieberman says Blue Zones diet marketing overstates evidence for living to 100, citing research he attributes to Oxford demographer Saul Newman. He argues many reported centenarians lack birth certificates and that self-reported ages make some longevity claims unreliable.
