We’re quick to blame genetics for our health and wellness issues, but the reality is that genetics only makes up 18% of our health destiny. That means the rest is up to us.

Our guest today, Dr. Grant Zarzour, has seen that first hand in his own family. When his son was diagnosed with moderate autism, he and his wife refused to accept the predictions for his future. They dove head first into the data and in so doing, revolutionized not just their son’s life, but their own. Now a relentless proponent of diet, sleep, and exercise for physical and mental health, Dr. Zarzour feels like we all have a hand in our own destiny. We just have to commit.

Dr. Zarzour is a practicing hip and knee surgeon in Mobile, AL. He is the president of the largest orthopaedic practice in Alabama. While treating thousands of patients a year, Grant has developed a passion for preventive medicine. In 2024, he founded Sperity Health, which offers personalized longevity coaching to help its members improve their diet, exercise, and sleep with expert MD guidance. Sperity Health’s mission is to lower its member’s risk of cancer, cardiovascular disease, and dementia by up to 50% based on data and science.

With the recent explosion of GLP-1 drugs, the war on obesity seems to have taken a new and potent turn, but many are concerned about the recidivism, the side effects, and our reenergized obsession with being thin.

Our guest today, Dr. Laure DeMattia, is a board certified family medicine physician and obesity specialist. For her, obesity is personal, as she has struggled her entire life with this chronic condition. In this episode, Dr. DeMattia breaks down for us how GLP-1 drugs work to hyperdrive weight loss, why that loss is rarely sustainable without long term use of the drugs, and her own philosophy outside of medication that helps her patients feel seen, heard, and safe. It’s both an educational conversation and a behind-the-curtains look at the obesity epidemic from someone on the front lines.

Dr. Laure DeMattia helps women stop blaming themselves for their physiology and find lasting health for over 20 years. Her dual perspective as both a doctor and a patient makes her uniquely compassionate, challenging the myth that willpower is the solution. Author of the book, The 4 Food Cues, Dr. DeMattia hosts her own YouTube channel, Navigating Obesity with Dr. D, where she offers a compassionate, realistic viewpoint about weight and weight loss.

As a society, and as an industrial complex, we’ve made health complicated…and expensive. But, epidemiology suggests that what we need to do to achieve and maintain personal health is really quite simple.

Dr. Tom Frieden returns to the show to talk about the second half of his book, The Formula for Your Health. Through extensive research and review of hundreds of epidemiological studies, he distills the findings down to six basic things we need to be doing in order to be healthy. Dr. Frieden acknowledges that there is nuance, but he also affirms that history is clear. There are other societies in the world that were and are far healthier than the US population, and NOT because they had wearables, packaged food, home massagers, or Pelotons.

Dr. Frieden is author of the book, The Formula for Better Health: How to Save Millions of Lives—Including Your Own. He is also the founder and CEO of Resolve to Save Lives, a global health organization that accelerates action against the world’s deadliest health threats. Resolve to Save Lives has worked with governments and other partners in more than 60 countries to save millions of lives. Dr. Frieden previously served as director of the U.S. Centers for Disease Control and Prevention (CDC) and New York City Health Commissioner, where he led efforts that increased life expectancy by 3 years and helped end major health crises including the largest US outbreak of multidrug-resistant tuberculosis, the 2014 West Africa Ebola epidemic, and responses to H1N1, Zika, and other threats.

Do you have an Apple watch? Fitbit? Oura ring? Woop? Wearables have taken over in the past decade with claims that by constantly monitoring our heart rate, sleep, respiration, and activity, they can provide health data that can change your life. But is that really possible? Or even plausible?

Marco Benitez, former professional athlete, and the Founder and CEO of ROOK joins us on the Living Well series today to talk all things wearables. He sees tremendous potential with how the data these tools compile can be utilized across all aspects of our lives, including in our cars (!), to change our behavior. But he acknowledges there’s a catch. Many of these companies use the data collected not for YOUR benefit, but for theirs, and real change, well, there’s no magic bullet. It’s hard, takes time, and is all on you.

Raised in Mexico with an insatiable curiosity and entrepreneurial spirit, Marco Benitez built his career at the intersection of health, technology, and sports science. Starting as a Tae Kwon Do champion, Marco’s discipline and resilience guided him into biomedical engineering, then into high-stakes roles in pharmaceutical giants like Roche and Novartis. Here, he witnessed the transformative power of data in healthcare—and saw a profound opportunity to make health metrics more accessible and actionable. Determined to improve health management and bridge the gap between raw data and real impact, Marco co-founded ROOK.

Last week, we talked about the six key drivers of personal health with Dr. Tom Frieden. But how does that factor into our conversation about the value (or not) of wearables and supplements?

This week, Dr. Zeev Neuwirth and Producer, Jess Greenwood, are back to unpack that for you. We discuss the role wearables do and potentially could play in helping each one of us achieve and maintain better health. We talk about how important it is to understand that the six drivers of personal health may be simple, but they’re not necessarily easy and why that means individuals are not to blame.

Most importantly, we offer an invitation. To those who are creating, supporting, or changing their own environments to support better health for themselves or their community. We want to hear from you! Please get in touch so we can share your story on the podcast.

“Healthcare, in my opinion, is the ultimate team sport.”

I love this quote from today’s guest. And it reminds me that patient experience is not just about the patient; it starts with every member of that patient’s care team. If they do not feel respected, trusted, and valued, it will absolutely impact the experience of their patients. Brian Carlson, VP of Patient Experience of Vanderbilt Health, knows that trickle down effect all too well. And, as a result, he’s been building the patient experience at that organization from the inside out.

The outcome?

• Year-over-year improvement in patient experience scores.
• Over 80% participation in voluntary patient experience training.
• Three times over having the organization vote “YES!” to continue this type of training.

Experience matters, and Brian has the data to prove it.

Brian Carlson leads enterprise strategy for patient experience, workforce culture, and digital engagement across the 40,000-person Vanderbilt Health system. Brian’s work focuses on the intersection of culture, operations, and technology, including AI-enabled approaches to experience management and patient engagement at scale. He has led major initiatives in patient access, digital health adoption, and workforce culture transformation.

Can design be a determinant of health?

We often think about the quality of the clinical care patients receive in our hospitals, the outcome metrics that determine funding and quality and safety rankings, the readmission rates that tell us how well we’re helping people get healthy and stay that way. But one thing we overlook is the quality, accessibility, and care in the buildings those same patients visit, the parking lots, the cafeterias, the sights, the sounds, the space as a whole.

Our guest today is an architect who looks at existing and possible solutions through a unique lens: Who was this designed for? Abbie Clary is CannonDesign’s Executive Director of Health for All where she leads strategy at the intersection of design, health equity and systems change. She has spent nearly 30 years impacting the healthcare system most directly across over $5 Billion in healthcare projects, including work with Memorial Sloan Kettering, University of Chicago Medicine, MD Anderson, Fred Hutch, Kaiser Permanente Shirely Ryan AbilityLab and more.

Her perspective that “design is bigger than buildings” is changing healthcare by creating opportunities for health in and around the spaces we as people inhabit in our daily lives. By building in those opportunities on the front end, Abbie believes there will be greater access, better outcomes, and an overall shift in health and wellness for all.
