What happens when a man who knows everything about nutrition still can’t change? In this episode, David Orozco, MS, RDN, uses the Alimentar persona Raj — a 43-year-old PhD and self-proclaimed Food Philosopher, to explore the hidden connection between high-saturated-fat diets, HPA axis dysregulation, chronic cortisol elevation, sedentary behavior, and cardiovascular disease risk. Drawing on eight peer-reviewed studies, David shows how these systems form a feedback loop that knowledge alone can’t break — and makes the case that the bridge between knowing and doing isn’t more data, it’s curiosity, joy, and one small bite.
