Harvard Professor: “I Tried Every Diet. This Is By Far The Worst.” - Daniel Lieberman - #1137
Summary
An evolutionary biologist reviews major diets, arguing that plant-based options generally offer better health outcomes than carnivore diets due to meat’s inflammatory compounds. He critiques the "Blue Zones" concept as statistically flawed and emphasizes that no single "optimal" diet exists for everyone. Instead, he advocates for a nuanced, evidence-based approach that prioritizes whole foods, sustainability, and individual needs over rigid nutritional dogmas.
