A "compassionate, authoritative, and wise" (Mark Hyman, MD, New York Times bestselling author of The Pegan Diet) 30-day program that "will shift the way you think about your body and your health" (Gabrielle Bernstein, #1 New York Times bestselling author and international speaker) based on a paradigm-shifting idea: You have to change your body to change your mind and mood.Prescription for Happiness offers a 30-day program for reaching a new level of energy, clarity, and calm. Too often, conventional medicine treats the mind as separate from the body. However, science shows that physical issues, such as chronic illness and weight fluctuation, are oftentimes intricately entwined with mental health conditions like depression, anxiety, fatigue, and more. This must-read 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 draws on cutting-edge research and her work with thousands of patients to tell the complete story of how our physical health influences our energy level, mood, focus, and emotional wellbeing. 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. Leveraging Parsley's unique patient data and successful proprietary protocols, Prescription for Happiness is the ultimate gateway to creating your new baseline for peak physical and mental health.
