Precision Nutrition is a behavior-based nutrition coaching system that combines evidence-based nutritional science with practical habit-building strategies. Founded by Dr. John Berardi and team, it’s widely known for its client-centered, sustainable approach to improving health, body composition, and performance. In the context of nutrition coaching, Precision Nutrition is applied by: Using habit-based change: Rather than overhauling a client’s entire diet, coaches introduce one behavior at a time (e.g., eating slowly, using hand portions) to build lasting change. Personalizing nutrition plans: Coaches adapt strategies to the individual’s goals, preferences, lifestyle, and readiness to change—rather than using cookie-cutter meal plans. Tracking progress holistically: Success is measured not just by weight, but also energy, mood, sleep, consistency, and behavior change. Focusing on education: Clients are taught why certain choices work better and how to problem-solve real-world situations (like travel, stress, or emotional eating). Supporting autonomy: Coaches act more like guides than dictators, helping clients develop internal motivation and confidence to sustain results long-term. In short, it’s not just about what to eat—it’s about how to make healthy eating stick.
