Deborah Kado is a professor at Stanford University School of Medicine, co-director of the Stanford Longevity Center, and board-certified geriatrician, specializing in bone health, osteoporosis, and aging-related syndromes. In this episode of The LIVING Room Podcast, she shares what decades of research in geriatrics and epidemiology reveal about what actually shapes quality of life as we age — bone health, hip fracture risk, muscle, posture, strength vs power, and why the difference between lifespan and healthspan is everything.

What we cover in this conversation:

• Why hip fractures are deadlier than most people realize 
• Whether bone density loss is actually reversible
• The difference between living longer and living well
• Why power matters more than strength as you age
• What Deborah wishes people in their 30s and 40s understood about aging now
• Why NAD supplements may be overrated
• What geriatricians actually do (and why there aren't enough of them)

For evidence-based insight on building lasting strength, mobility, and independence — free from the noise of longevity hype — this episode delivers.

Dariush Mozaffarian, MD, PhD — Dean Emeritus at the Tufts University School of Nutrition and Director of the Food Is Medicine Institute — has spent decades studying why we get sick, why we gain weight, and why so much of what we've been told about food is overcomplicated at best, and actively harmful at worst. In this conversation, he dismantles the myths driving the obesity epidemic and replaces them with what the evidence actually shows.

In this episode, you’ll learn:

• Why counting calories is a bad approach— and what actually drives weight gain
• Why most high-protein advice is backwards, and what you should be eating instead
• The real story on seed oils and ultra-processed foods (it's more nuanced than the headlines suggest)
• What GLP-1 drugs can and can't do — and why they're not the whole answer
• The truth about alcohol and how it relates to your wellness
• How to lose body fat and keep it off
• How to build a sustainable way of eating that supports your metabolism, your heart, and your long-term health

If you've ever felt paralyzed by conflicting nutrition advice, this episode cuts through the noise. Dr. Mozaffarian doesn't deal in trends — he deals in evidence. And the picture he paints is both surprising and deeply clarifying.

Most of us think of aging as something that just happens to us. Dr. William Mair thinks differently — and after 30 years studying the biology of aging at Harvard, he doesn’t deal in theory – he deals in evidence.

In this conversation, Dr. Mair unpacks why age is the single biggest risk factor for nearly every chronic disease — from Alzheimer's to cancer to cardiovascular disease — and why targeting aging itself may be the most powerful thing we can do for human health and performance. But more importantly, he brings it back to you: what can you actually do, right now, to influence the rate at which your body ages?

You'll walk away understanding: 

• Why your lifestyle choices are actively speeding up or slowing down your biological clock 
• What the science actually says about sleep, nutrition, and exercise, and how to optimize those habits to support healthspan
• How to cut through the longevity noise — supplements, biohacks, and what's real vs. hype
• Why "healthspan" matters more than lifespan — and how to protect it 
• What emerging science could change everything about how we age in the next 10–15 years

Chronological age is fixed. Biological age isn't. This episode gives you the peer-reviewed science to understand the difference — and how to act on it.
