SAMA HOOLE: “Rabbit starvation” is protein poisoning. Too much lean [protein] = liver overload, nausea, diarrhea, death.

3. We Invented Tools Specifically To Get More Fat

Paleolithic tools weren’t made for carving steaks.
They were built for fat extraction:

– Hammerstones: smashed bones for marrow
– Scrapers: cleaned hides for fat-rich membranes
– Awls: pierced hides to access brains
– Boiling… pic.twitter.com/Kc4Nr8hcmL

Hoole adds that,

Rabbit Starvation “Rabbit starvation” is protein poisoning. Too much lean [protein] = liver overload, nausea, diarrhea, death. Because the body can only metabolise around 35-40% of its energy needs from protein. Observed in Arctic explorers, and still taught in survival training today.

“If you eat rabbit exclusively, you’ll die sooner than if you eat nothing.” — Vilhjalmur Stefansson

Hoole points out that,

The Brain Prefers Fat Your brain is 60% fat, burns 500 calories a day, and needs fats like DHA…only found in animal foods. Without the caloric density of fat, as well as the key nutrients, our ancestors would never have been able to support such a brain.

And in case you think the brain runs best on glucose, it will actually pick ketones when given the choice.
