A 30-day program for reaching a new level of energy, clarity, and calm, based on a paradigm shifting idea: You have to change your body to change your mind and mood.

Too often, conventional medicine treats the body as separate from the mind, ignoring physical issues like chronic illness and weight gain. Science shows that these issues are oftentimes intricately entwined with mood issues like depression, anxiety, stress, and persistent fatigue.

In State Change, Dr. Berzin draws on cutting-edge research and her work with thousands of patients to tell the complete story of how our bodies drive our minds, mood, and energy levels. This builds on her work at her nationally renowned holistic health service Parsley Health, where Dr. Berzin and her team of over 100 highly trained medical providers focus on treating the whole patient, yielding extraordinary results for those dealing with gastrointestinal, hormone-related, autoimmune, and mental health conditions.

This trailblazing book explores the new science of optimizing the body in ways that will help anyone attain a new baseline for energy, calm, and optimism. Dr. Berzin believes that treating common imbalances in the body is the only way to achieve what she calls a state change–a transformation to higher levels of mental focus, emotional stability, and flow.

Leveraging Parsley’s unique patient data and successful proprietary protocols, State Change includes a 30-day program for resetting the body, mind, and mood. With easy-to-understand advice and detailed personalized assessments, State Change is the ultimate gateway to a positive mental state and peak physical health.
