Harvard Professor: “I Tried Every Diet. This Is By Far The Worst.” - Daniel Lieberman

What was said

"So the NIH redid the experiment and this time they had On the same monkey chow diet. Just chopped one in half or whatever. And one had 30% less food than the other. And guess what? No difference. Zilch in terms of health and longevity."

Discussing calorie restriction as a longevity strategy, Lieberman says a headline-making Wisconsin macaque study was confounded because the control group were effectively fed an unhealthy, obesity-promoting diet. He claims a later NIH replication using comparable diets, with a 30% calorie reduction arm, found no difference in longevity or health outcomes.
