All guides
Learn the schools
Pick a lineage, pick a depth, dig in. Every guide is tagged so you know what it is — a school, a thinker, the deep cuts, or the science behind the app — before you open it.

The eight schools
Each way of eating Metras speaks — sourced, explained, and honest about its tradeoffs. Choosing one sets your targets, verdicts, and coach.
Pro-metabolic
Eat for a warm, energized metabolism. Fruit, milk, honey, gelatin, almost no PUFA.
Instinctive Raw
Raw animal foods, high fat, enzyme-rich. Cream, eggs, meat, honey, juiced veg.
Seafood + Circadian
Fatty fish, animal fats, and daily sunlight. Heart and mitochondria first.
Carnivore
Animal foods only. Simple, therapeutic, ruthless about removing friction.
Full Plate
The full range of real food: meat, fish, dairy, fruit, vegetables, eggs. Nothing off-limits, nothing processed.
Animal-Based
Meat is the foundation, fruit is the decoration. Animal foods plus fruit, honey, and least-toxic plants.
Seasonal Ancestral
Traditional, nutrient-dense whole foods rotated with the seasons and your local environment (Price, Fallon, WAPF).
High Carb Athlete
Evidence-based performance fueling: high carbs scaled to training load, moderate protein, lower (not low) fat. Sports-nutrition consensus, not a health philosophy.

The thinkers and the deep cuts
Two schools have a whole library behind them — the person who built the idea, and the advanced tips underneath it.
Pro-metabolic
Cross-cutting
Science and app metrics
The reading that isn't tied to one school — the light science underneath the app, and how the daily scores are built.
