Diets in human evolutionary history were primarily based on animal foods, and modern diets that differ from this pattern are linked to higher rates of metabolic disease and body fat accumulation.
See the scientific wording
Human evolutionary dietary patterns were dominated by animal-based foods, and deviations from this pattern are associated with increased prevalence of metabolic disease and adiposity.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Systematic Review of Pre-Industrial Human Diets and Metabolic Disease Prevalence Across Populations
Population: Historical and contemporary human groups with documented dietary patterns; Intervention: Comparison of animal-based vs. plant-based dietary dominance; Comparator: Groups with high vs. low deviation from presumed ancestral diet; Outcome: Prevalence of metabolic disease and adiposity measures; Duration: Long-term population-level data across generations.
Prospective Cohort Study of Dietary Patterns Mimicking Ancestral Diets and Incidence of Metabolic Disease Over 20 Years
Population: Healthy adults aged 25–65 with baseline dietary assessment; Intervention: Long-term dietary patterns classified as ancestral-like or deviant; Comparator: High vs. low adherence to ancestral dietary pattern; Outcome: Incidence of metabolic disease and change in adiposity; Duration: Minimum 15–20 years.
Cross-Sectional Analysis of Dietary Composition and Metabolic Disease Prevalence in Modern Populations with Varying Ancestral Diet Adherence
Population: Diverse adult populations with documented dietary intake; Intervention: Classification of diet as ancestral-like or deviant; Comparator: Groups categorized by dietary deviation; Outcome: Prevalence of metabolic disease and adiposity measures; Duration: Single time point.
Case-Control Study Comparing Historical Dietary Patterns in Individuals with Metabolic Disease vs. Healthy Controls
Population: Adults with diagnosed metabolic disease and high adiposity (cases) vs. matched healthy controls; Intervention: Retrospective assessment of dietary patterns; Comparator: Degree of deviation from ancestral dietary patterns; Outcome: Association between dietary deviation and disease status; Duration: Retrospective data collection.
Animal Model Study of Metabolic Outcomes in Rodents Fed Ancestral vs. Modern Diets Over Multiple Generations
Population: Genetically similar rodents; Intervention: Feeding ancestral diet (high animal protein/fat, low carbohydrate) vs. modern diet (high processed carbs/fats); Comparator: Two dietary groups; Outcome: Metabolic markers, adiposity, insulin sensitivity; Duration: Multiple generations.
