Longevity Made Simple

“Want to add years to your life and life to your years? To live longer and better? Here’s how!  Elegantly and clearly written by renowned experts who understand healthy living so well they can make it simple. Highly recommended!”

“As a physician deeply committed to root-cause medicine and transforming our broken healthcare system into one that promotes true health, I am thrilled to see a book like Longevity Made Simple enter the world. Dr. Shad and Dr. Carmona, two leading voices in preventive medicine and public health, have written an inspiring and accessible roadmap for how we can live healthier, longer lives.

Their DRESS Code—Diet, Relationships, Exercise, Stress, and Sleep—is more than just an acronym. It is a science-based, lifestyle-first framework for rewiring how we think about health, aging, and disease. Drawing from real patient stories, cutting-edge research on epigenetics and lifestyle medicine, and decades of clinical and public health leadership, this book powerfully bridges the gap between what we know and what we do.

“In a time when most healthcare is focused on reactive disease management, this book empowers individuals to take control of their biology, upgrade their habits, and extend not just their lifespan but their healthspan. Longevity Made Simple is essential reading for anyone who wants to prevent disease, reverse chronic conditions, and unlock their fullest potential. This book is a must-read for anyone who wants to live not just longer, but better.”

“Longevity Made Simple is a compelling and practical guide to living better for longer. Dr. Shad Marvasti and Dr. Richard Carmona have masterfully distilled the complex science of epigenetics to explain the foundational lifestyle principles we uncovered in the world’s longest-lived communities into actionable strategies for everyday life. The DRESS Code offers a clear, structured path to better health, empowering readers from all walks of life to take small, sustainable steps toward a longer, more meaningful life. It’s an inspiring companion for anyone who wants to live a longer, happier life with more vitality, joy, and purpose. This book is both a science-based roadmap and an invitation—to take control of your health and thrive.”

“Longevity Made Simple is both medically sound and deeply human. Dr. Shad and Dr. Carmona bring years of clinical expertise and public health leadership to a message that is as inspiring as it is actionable. Through the DRESS Code—Diet, Relationships, Exercise, Stress, and Sleep—readers will receive a proven, science-based path to prevent disease and extend not just their lifespan, but their healthspan. This book is a much-needed guide for anyone who wants to take charge of their health and live with greater clarity, vitality, and purpose.”

“Longevity Made Simple is a timely and transformative contribution to the future of health and well-being. Dr. Shad and Dr. Carmona have shared the latest science and real-world clinical experience in the form of an accessible framework—the DRESS Code—that is both practical and profoundly empowering. This book aligns perfectly with the mission we champion at the Lake Nona Impact Forum: to shift from reactive care to proactive, personalized, and preventative health strategies that help communities and individuals thrive. It’s a must-read for anyone working to create healthier, more resilient lives and systems.”

“Longevity has suddenly become an overly complex, confusing, and expensive pursuit. In all my decades in the wellness space, this book provides the most dazzlingly simple—but most science-backed—roadmap to living healthier and longer. By focusing on the DRESS code—making very doable changes in your diet, relationships, exercise, sleep, and stress—you can achieve a powerful epigenetic ‘reset,’ literally turning on or off thousands of your genes in just a few weeks. You don’t need to be a billionaire to biohack your healthspan, you just need this book.”
