Metabolic Psychiatry by Prince Penman

What if mental illness isn't just in your head—but in your metabolism? For decades, we've been told that depression is a chemical imbalance, anxiety is a faulty brain circuit, and bipolar disorder is a mood regulation problem. But what if the real story is metabolic? In Metabolic Psychiatry, Prince Penman reveals the groundbreaking science that is transforming our understanding of mental health. Drawing on decades of research, he shows how insulin resistance, inflammation, mitochondrial dysfunction, and nutrient deficiencies can drive—and often cause—depression, anxiety, bipolar disorder, and even schizophrenia. But this book is not just theory. It's a practical, step-by-step guide to healing your brain by healing your metabolism. You'll learn: •How to recognize the hidden signs of metabolic dysfunction •The spectrum of dietary strategies—from low-carb to ketogenic—and how to choose what works for you •The critical nutrients your brain needs to function •How fasting and time-restricted eating can boost brain energy •How to track biomarkers and symptoms to personalize your plan •How to work with your clinician safely and collaboratively •How to sustain change over the long term If you or someone you love has struggled with mental health—especially if conventional treatments haven't worked—this book offers a new path forward. A path grounded in science, hope, and the recognition that your brain is an organ, your metabolism matters, and recovery is possible. Your brain is not broken. Your metabolism may be struggling. And that is something you can change.
