Jennifer Ashby, a senior clinician at the UCSF Osher Center for Integrative Health with over 30 years of clinical experience in women's health, draws on both East Asian medicine and modern science to reframe menopause not as decline but as a dynamic transformation. Rooted in her decades of direct patient care and doctoral-level research, this book offers women navigating perimenopause and menopause an evidence-informed, whole-person approach to reclaiming energy and vitality during midlife hormonal change. The Energy Prescription introduces the Basic Optimal Outcomes Method (BOOM) and its EPIC 8 lifestyle framework, addressing eight fundamental areas women must optimize: diet, hydration, sleep, breathwork, exercise, elimination and gut health, joy, and stress management. Rather than focusing solely on hormones or pharmaceuticals, the book integrates ancient healing traditions with current lifestyle medicine to tackle common symptoms including hot flashes, brain fog, mood swings, and sleep disruption through practical, implementable strategies. Readers gain access to self-assessments and practical tools designed to help them understand their individual symptom patterns and build personalized approaches to midlife health. Ashby challenges the cultural narrative that equates aging with invisibility, instead positioning this life stage as a powerful rite of passage. Each chapter provides deeply relatable insights drawn from her clinical work with thousands of women, connecting real-world experience with actionable guidance for lasting change. Written for women aged 40 to 65 seeking holistic, evidence-based solutions for perimenopause and menopause symptoms such as fatigue, brain fog, and sleep disruption, this book also serves women in their 30s preparing for midlife transitions. Wellness professionals and integrative healthcare providers will find it a valuable resource for supporting their clients and patients through hormonal change with culturally informed, whole-person strategies.
