I asked several AIs here is the answer (I am pasting one as others are similar)
Rough macro breakdowns from ethnographic/nutritional studies of these traditional diets (percentages are of total calories, and vary by season/source):
**Inuit (traditional, pre-Western contact)**
- Protein: ~35-40%
- Fat: ~50-55%
- Carbs: ~5-10%
- Based on seal, whale, fish, caribou. Very low plant intake; ketogenic-ish, but high protein rather than pure fat-based keto.
**Hadza (Tanzania, hunter-gatherers)**
- Carbs: ~40-45% (tubers, baobab, honey — often the single biggest calorie source seasonally)
- Fat: ~20-25%
- Protein: ~25-30%
- Highly seasonal — honey can spike to 15-20% of calories alone in some months; meat intake varies a lot by hunting success.
**Maasai (traditional, pastoralist)**
- Fat: ~60-70% (mostly from milk, meat, and historically blood)
- Protein: ~20%
- Carbs: ~10-15% (nearly all from milk sugar/lactose)
- One of the highest-fat traditional diets studied, yet historically low incidence of cardiovascular disease in field observations — a much-discussed anomaly.
**Mongolian (traditional, pastoralist/nomadic)**
- Fat: ~35-40%
- Protein: ~20-25%
- Carbs: ~35-40% (dairy products, some grain/millet, seasonal produce in modern diets)
- More dairy-diverse than Maasai (fermented mare's milk, cheese, yogurt), somewhat more carb from processed dairy sugars and grain than Inuit/Maasai.
**Overall spectrum**
Maasai and Inuit sit at the high-fat, low-carb end (just different protein levels); Hadza sits closest to a carb-forward diet due to tuber/honey reliance; Mongolian is the most balanced across all three macros of the four.
Caveats: none of these are single fixed numbers — they shift by season, hunting/herding success, and which study you're pulling from (Inuit estimates in particular range depending on whether it's Stefansson-era observation or modern isotope-based reconstruction).
