Episode notes
No Single Ancestral Diet
- Ancestral diets varied widely by environment; some populations were fat-heavy, others carb-rich.
- Metabolic flexibility, not a single ancestral template, explains adaptation to local foods.
Pick Diets You Can Sustain
- Use ketogenic diets for weight loss only if they suit your food preferences and are sustainable for you.
- Choose a diet that reduces calories reliably, not one you must 'white knuckle' to maintain.

- Keto increases fat oxidation but does not reliably improve high-level athletic performance.
- Elite athletes still rely on carbs because high-intensity output requires fast ATP from glycolysis.
