The transcript doesn't provide the specifics of the 1985 study Dr. Shawn Omera referenced, only that an anthropologist used MRIs of ancient ancestors to conclude that they did not have high amounts of metabolic dysfunction or visceral fat. More information about the study itself is not available in the provided transcript.
This video discusses a fasting mistake the speaker, Thomas DeLauer, made for ten years. He explains that structuring his fasts with rigid time periods, instead of incorporating randomness in the fasting duration, hydration, and intensity of workouts, was counterproductive. He proposes a more naturalistic approach mimicking the unpredictable eating patterns of our ancestors and wild animals.
