Feb 6, 2026

A provocative tour through evidence that humans can thrive without carbohydrates. Discussions cover ketogenic physiology, gluconeogenesis, and how fat and protein fuel the body. They explore links between carbs and dental/health changes since agriculture, plant toxins and autoimmune triggers, and practical guidance for a high-fat carnivore approach.

ADVICE

Remove Plants For Autoimmune Flare-Ups

Remove plant foods if you have autoimmunity because plant toxins can trigger flare-ups.
Try a plant-free ketogenic (carnivore) approach when autoimmune symptoms persist despite other changes.

INSIGHT

Insulin Matches Protein, Not Carbs

Human insulin better matches the metabolic response to protein than to carbohydrate spikes.
Chaffee notes synthetic fast-acting insulins were developed to match carbohydrate-induced glucose peaks, implying insulin evolved for protein handling.

INSIGHT

Agriculture Coincides With Dental Decline

Dental health shifted sharply after agriculture, with cavities and jaw shrinkage emerging once carb-rich foods spread.
Chaffee links tooth decay and changed dentition to carbohydrate introduction after agriculture.
