About the session
Moving beyond managing disease, toward healthier years
As longevity science evolves, we are gaining a deeper understanding of the biological mechanisms that drive aging and the role lifestyle interventions play in influencing them. Moving beyond traditional disease prevention, longevity medicine focuses on extending healthspan, the years lived with physical vitality, cognitive function, and independence.
This session will explore the intersection of lifestyle medicine and longevity science, examining how nutrition, physical activity, sleep, stress, and metabolic health influence the biological pathways of aging. Particular attention will be given to emerging research on fasting and fasting-mimicking diets (FMDs), including their effects on metabolic regulation, nutrient sensing, cellular stress responses, and biomarkers of aging.
We will also address preserving muscle mass and supporting metabolic flexibility, while distinguishing established clinical benefits from promising areas of ongoing research.
Finally, we will explore how longevity science can be translated into personalized, sustainable clinical care, introducing the Longevity Program as a comprehensive model that integrates evidence-based nutrition, periodic FMD, individualized lifestyle guidance, and monthly expert-led deep dives on metabolism, muscle health, and nutrition.
The session aims to help clinicians move beyond managing disease toward a proactive, personalized approach to healthy aging. The goal is not simply to add years to life, but to add healthier, more vibrant years to the lives we lead.

Meet the clinicians leading the session
Dr. William Hsu, MD
Chief Medical Officer, L-Nutra
Dr. William Hsu is a leading endocrinologist and innovator in metabolic health with more than two decades of experience at the forefront of diabetes care. After 20 years at Harvard's Joslin Diabetes Center, where he served as Vice President and led global advisory initiatives across 12 countries, Dr. Hsu joined L-Nutra in 2019 as Chief Medical Officer to drive forward a new paradigm in chronic disease care.
At L-Nutra, Dr. Hsu leads clinical strategy, medical and scientific affairs, and the development of L-Nutra Health, a groundbreaking division focused on the remission and regression of type 2 diabetes using nutrition-based therapeutic approaches, including the Fasting Mimicking Diet (FMD). His vision: to reduce reliance on medications by harnessing the body's innate capacity for repair and metabolic restoration.
Dr. Hsu has played a pivotal role in shaping national standards of diabetes care through his service on multiple American Diabetes Association committees. His research has explored the pathophysiology of diabetes and the role of digital health technologies in managing chronic disease.
He earned his medical degree from the Icahn School of Medicine at Mount Sinai, completed his internal medicine residency at Yale School of Medicine, and trained in endocrinology and metabolism at Harvard Medical School, where he also served as Assistant Professor of Medicine.

Ashley leads a global team of registered dietitians delivering evidence-based metabolic care and oversees the development of clinical training programs implemented by healthcare providers around the world. She works closely with the Chief Medical Officer to advance innovative nutritional interventions aimed at improving metabolic health and supporting type 2 diabetes remission.
Ashley has been instrumental in developing clinically validated programs at L-Nutra Health, with outcomes recognized at the American Diabetes Association's 85th Scientific Sessions, where program data was selected for an oral abstract presentation. She has also presented at ADCES (Association of Diabetes Care and Education Specialists) and the American College of Lifestyle Medicine (ACLM) for two consecutive years, and regularly delivers educational sessions, webinars, and keynote presentations to clinicians, health systems, and corporate audiences internationally.
Her work focuses on translating emerging longevity and metabolic science into practical, scalable clinical programs that help providers improve outcomes for patients with obesity, diabetes, cardiovascular disease, and metabolic syndrome. Ashley has also played a key role in expanding L-Nutra Health programs internationally, including launching clinical initiatives in the United Kingdom and Europe, and representing the organization at international press conferences and medical forums.
Before joining L-Nutra Health, Ashley spent more than a decade in hospital-based clinical practice, specializing in nutrition therapy for diabetes, cardiovascular disease, renal disease, critical care, and weight management. She later transitioned into preventive and lifestyle-focused care, leveraging nutrition science, telehealth, and behavior change strategies to address chronic disease at scale at Vida Health and Cecelia Health.
Ashley is a Registered Dietitian and Certified Diabetes Care and Education Specialist, and an active member of the Academy of Nutrition and Dietetics, the American Diabetes Association (ADA), and ADCES. She earned her Bachelor of Science in Food Science and Human Nutrition from Clemson University in 2004.
