Genetic Weight Types and Their Historical Roots

Genetic Type D offers a vivid illustration of dietary evolution shaped profoundly by geography. Originating primarily from Caribbean islands and tropical regions abundant in fruits, vegetables, and lush vegetation—but scarce in livestock—populations genetically adapted to plant-based sustenance. Indigenous groups, such as the Taíno and Carib, thrived on starch-rich tubers, tropical fruits, and legumes, establishing metabolic efficiencies tailored to a largely vegetarian diet.

Later historical forces further defined this genetic landscape. The transatlantic slave trade brought millions of Africans—bearing their ancestral dietary flexibility—to Caribbean shores. Here, African and indigenous genetics intertwined, solidifying Type D’s adaptation to tropical vegetation. Today, those inheriting this genetic type typically experience optimal health when prioritizing fresh produce, nuts, legumes, and starches, while excessive animal protein—foreign to their ancestral tables—often disrupts metabolism, leading to weight gain and inflammation.

Understanding this genetic dietary heritage allows individuals of Type D descent to align their modern food choices with ancestral biology. It’s a subtle act of respect for the centuries of adaptation hidden within their DNA.
