Aging is universal — but how we age is anything but. In this powerful episode of Wellness Connection MD, Dr. Jim McMinn and Coach Lindsay Mathews welcome Dr. Jerry Kitchens to explore a functional medicine approach to longevity and healthspan.

Dr. Kitchens, a Birmingham native and former general surgeon, practiced for 23 years before osteoarthritis in his hands led to early retirement. That turning point — combined with his father’s diagnosis of mild cognitive impairment progressing to Alzheimer’s — ignited a new professional passion. After completing rigorous Institute for Functional Medicine (IFM) training, he launched Homewood Health and Wellness and now serves as Medical Director of Birmingham Longevity Clinic.

Together, the team dives deep into the difference between lifespan and healthspan, chronological age versus biological age, and whether aging should be viewed as a disease process or a natural part of life. The discussion explores the foundational pillars of healthy aging — including nutrition, exercise, sleep, muscle mass, inflammation control, insulin sensitivity, mitochondrial health, gut health, toxin reduction, hormone optimization, and emotional well-being.

They also tackle:

The “5 Horsemen of Disease” and how to prevent or manage them
The critical role of muscle mass in predicting longevity
How the microbiome influences aging
The impact of inflammation and insulin resistance
Functional lab testing: optimal vs. normal ranges
Key biomarkers to track annually
The role of genetics and epigenetics
Loneliness, purpose, and social connection as determinants of healthspan
Practical, actionable steps listeners can begin tomorrow

This episode moves beyond simply living longer — and focuses on living stronger, sharper, and more engaged for as many years as possible.

If you’re interested in extending not just your lifespan but your healthspan, this conversation is packed with evidence-based, practical insights you won’t want to miss.
