[2:36] Early man's gut shrank as the brain grew in size. | Miki-Ben Dor's paper "Man the fat hunter" https://bit.ly/2DhE91W and Aiello & Wheeler's paper "The expensive tissue hypothesis" https://bit.ly/2DgbWJ1 talk more about this.

[2:40] Regarding how the ability to ferment fiber for fat energy was something lost for humans, see "The Western Lowland Gorilla Diet Has Implications for the Health of Humans and Other Hominoids" https://bit.ly/2CtpQWm "...the human colon may contribute as little as 2-9% to total energy compared with possibly 30-60% for the gorilla."

◆4:06 - What is the state of a baby's metabolism?

[4:20] Babies are in ketosis:

・George Cahill's "Fuel Metabolism in Starvation" https://bit.ly/2DhDn4Q (behind a paywall, but the relevant snippet is shown here: /youtube/video/yooNuOKsa1Q

・See "Ketone Body Transport in the Human Neonate and Infant" - https://bit.ly/2CxPNnE

[11:38] For more on the antioxidant properties of a ketogenic diet, see "Anti-Oxidant and Anti-Inflammatory Activity of Ketogenic Diet: New Perspectives for Neuroprotection in Alzheimer’s Disease" https://bit.ly/2W0m7bN "The ketogenic diet (KD) stimulates the cellular endogenous antioxidant system with the activation of nuclear factor erythroid-derived 2 (NF-E2)-related factor 2 (Nrf2), the major inducer of detoxification genes."
