Imagine waking up feeling energized, maintaining stable energy all day, and watching stubborn health issues gradually disappear. This isn't fantasy - it's what happens when we align our eating with our evolutionary design. For 2.5 million years, humans thrived as hunter-gatherers, consuming lean wild meats, fresh fruits, and vegetables. Then, just 10,000 years ago - a mere blink in evolutionary time - agriculture changed everything. Our bodies, genetically identical to our Paleolithic ancestors, suddenly faced foods they were never designed to process. Our bodies remain calibrated for a world that no longer exists. Archaeological evidence reveals that early farmers were 5-6 inches shorter than their hunter-gatherer predecessors, suffered more infectious diseases, experienced 50% higher childhood mortality, and developed dental problems previously rare. Why? Their nutritious diet of lean meats and plant foods was replaced with starchy cereals lacking essential nutrients. This represents the most profound change in human nutrition history, yet our genetic makeup has changed less than 0.02% since agriculture began. We're essentially Stone Age humans living in a Space Age world. Today's standard American diet derives 71% of calories from foods that didn't exist in the Paleolithic era: cereals, dairy, refined sugars, and industrial oils. The average American consumes 156 pounds of added sugar annually - compared to our ancestors who might have found honey a few times a year. This mismatch explains why 68% of American adults are overweight or obese and why "diseases of civilization" have reached epidemic proportions. The Hadza people of Tanzania, among the last hunter-gatherers, show virtually none of these conditions despite living into their 70s and 80s. As one Baffin Island Eskimo poignantly observed: "We never used to be so sick. The white man's food is not good for us."
