Sherwood doctors release 'Authentic Longevity' book on whole-body aging

Drs. Mark and Michele Sherwood have released a new book that argues longevity depends on more than treating symptoms, tying together physical, mental, emotional and spiritual health. The Tulsa-based clinicians say the guide aims to help readers build vitality, purpose and resilience as interest in personalized aging grows.

Why it matters: - The book pushes back on the idea that longevity is mainly about adding years. - The Sherwoods frame healthy aging as a mix of energy, strength, clarity and purpose. - The message lands as interest grows in longevity science, biological aging and personalized health.

What happened: - Dr. Mark Sherwood and Dr. Michele Sherwood released Authentic Longevity: Unlocking Lifelong Vitality, The Sherwood Way on August 20, 2026. - The Sherwoods are co-founders of the Functional Medical Institute in Tulsa, Oklahoma. - The book is billed as a guide to health and longevity that challenges symptom-only thinking.

The details: - The Sherwoods draw on decades of clinical experience and work with tens of thousands of patients. - The book combines actionable science, patient stories and personal experiences with adversity. - The central argument is that the body should not be treated as isolated parts. - The Sherwoods say longevity depends on how nutrition, movement, sleep, stress, hydration, metabolism, genetics and other biological factors interact. - The book is split into two main parts: “What We Can Control” and “Where We Need Help.” - “What We Can Control” covers nutrition, movement, sleep, stress and hydration. - That section focuses on habits that can affect energy, metabolic health, performance, recovery and healthy aging. - The Sherwoods emphasize sustainable habits rather than extreme diets, short-term trends or “longevity hacks.” - “Where We Need Help” covers genetics, peptides, supplements, hormones and laboratory testing. - That section introduces readers to longevity tools that may require professional guidance. - The book says no single treatment, supplement or emerging therapy is a universal solution. - The Sherwoods also argue that spiritual and emotional health are often missing from longevity discussions. - The book links purpose, belief, relationships and emotional wellbeing to physical health. - The authors say lifespan has limited value without vitality, independence and purpose. - The book includes direct quotes from the Sherwoods on their view of longevity and health. - Dr. Mark Sherwood says, “Health isn't something you find. It's something you build every day.”

Between the lines: - The book reflects a whole-person model that blends conventional wellness topics with faith, resilience and personal narrative. - Dr. Michele Sherwood’s story includes elite Taekwondo competition, a serious knee injury and a period of financial hardship in which she lived in her car for three months. - Dr. Mark Sherwood’s background includes law enforcement and service on a SWAT team before moving into health, wellness and clinical practice. - Those experiences helped shape the Sherwoods’ view that resilience goes beyond physical health. - The Functional Medical Institute’s work centers on nutrition, metabolism, hormones, inflammation, sleep, stress and lifestyle. - The practice emphasizes prevention and active patient participation in long-term wellbeing. - The book has endorsements from Lou Ferrigno, Lisa Bevere, Dr. Don Colbert and Kevin Sorbo.

What's next: - The Sherwoods say readers should start with the fundamentals they can control before exploring advanced longevity tools. - The authors position individualized professional guidance as important for more complex health decisions. - More attention is likely as the book enters a market already focused on extending healthspan, not just lifespan.

The bottom line: - Authentic Longevity argues that aging well is built through daily habits, personalized care and a sense of purpose, not quick fixes.
