Macro partitioning

Diets based largely on plant foods promote health and longevity, whereas the specific macronutrient ratios proposed for Paleolithic diets (high protein, low carbohydrate) are not supported by sufficient evidence to define a genetically determined optimal diet.

Focus on eating a diet where plant foods (fruits, vegetables, grains) make up the majority of your intake. Do not worry about replicating specific high-protein or low-carb ratios attributed to the Paleolithic era, as the evidence for those specific numbers is weak. Prioritize plant abundance for health and longevity.

ModerateQualifiesMEDIUM confidence
The evidence related to Paleolithic diets is best interpreted as supporting the idea that diets based largely on plant foods promote health and longevity... The evidence related to Paleolithic diets is circumstantial, incomplete, and debatable and there are insufficient data to identify the composition of a genetically-determined optimal diet.

Why this rating

The paper is a review of archaeological and anthropological evidence, which is inherently circumstantial and incomplete compared to clinical trials.
