Macro partitioning

Adopting a hunter-gatherer-style macronutrient profile (approx. 35% fat, 35% carbs, 30% protein) with high polyunsaturated fat intake and minimal refined sugars improves metabolic health markers compared to the standard Western diet.

To align with your evolutionary biology, structure your diet to include roughly equal parts fat, carbohydrates, and protein by energy. Prioritize polyunsaturated fats (like those in wild game and plants) over saturated fats, and keep added sugars to a minimum (under 3% of energy). Aim for high fiber intake (>100g/day) from fruits and vegetables, and maintain a high potassium-to-sodium ratio. This approach is associated with lower serum cholesterol and reduced risk of chronic degenerative diseases compared to the standard Western diet.

ModerateSupportsMEDIUM confidence
The best available estimates suggest that those ancestors obtained about 35 % of their dietary energy from fats, 35 % from carbohydrates and 30 % from protein... Polyunsaturated fat intake was high, with n-6:n-3 approaching 2 :1 (v. 10 : 1 today)... Honey comprised 2–3% energy intake as compared with the 15 % added sugars contribute currently.

Why this rating

The evidence is based on retrojected estimates from modern hunter-gatherer groups and evolutionary theory, not direct RCTs on the ancestral diet itself.
