Peptides, FDA Approval & Longevity Trends: Dr. Myles Spar Separates Science From Hype

Peptides, FDA Approval & Longevity Trends: Dr. Myles Spar Separates Science From Hype

The peptide space is exploding. Claims are everywhere. But for most peptides, the human evidence is still surprisingly limited. Dr. Myles Spar is a board-certified Internal Medicine physician, Integrative Medicine physician, and Clinical Translator at The WNDR Lab. He has spent his career helping translate longevity science into practical medicine, and in this conversation, he breaks down one of the most talked-about topics in health today: peptide therapy. From BPC-157 and TB-500 to MOTS-c and GHK Copper, Dr. Spar explains why the excitement has outpaced the evidence, what the FDA's proposed recategorization of certain peptides actually means (and what it doesn't), and how to evaluate health claims before putting anything in your body. The conversation also explores how to separate evidence from hype, why correlation isn't causation, and why the fundamentals of health still outperform any shortcut. This episode also marks the launch of a new recurring series: The Truth Behind the Trend”  on The LIVING Room Podcast. In this series, Chris Wharton sits down with leading experts in their fields to examine what's making the news, what the science says, and what it actually means for your health. These shorter conversations are designed to help you think more critically, ask better questions, and separate evidence from hype.  What we cover in this episode: * Why most peptide research is still limited—and why that matters * BPC-157, TB-500, MOTS-c, and GHK Copper: what we know today * What the FDA's proposed peptide recategorization means—and why it does not mean FDA approval * The difference between FDA-approved, FDA-cleared, and compounded products * Why injectable peptides have more evidence behind them than patches, creams, and sublingual formulations * The risks of buying peptides from unregulated sources * Why therapeutic plasma exchange may be overhyped in longevity medicine * The "proof commensurate with harm" principle for evaluating health interventions * Why correlation does not equal causation in health research * How to run your own N-of-1 experiment to determine what actually works for you * Why exercise, sleep, nutrition, stress management, and other fundamentals remain the foundation of longevity If you're trying to make sense of the rapidly growing world of peptides, biohacking, and longevity medicine, this episode offers a practical, evidence-based framework for thinking critically about the latest health trends.

Healthspan, Not Lifespan: Harvard Researchers on Why Staying Healthy Matters More Than Living Longer

What if the greatest opportunity to prevent cancer, Alzheimer's disease, frailty, and many of the chronic conditions that shorten our lives isn't treating them one by one, but addressing the biology of aging itself? Harvard researchers Raiany Romanni-Klein, PhD and William Mair, PhD join The LIVING Room Podcast to explore why biological aging may be one of the most consequential, and most overlooked, modifiable risk factors in modern medicine, and why rethinking how we age could fundamentally reshape the future of healthcare. For decades, medicine has focused on treating age-related diseases one at a time. But what if the biology driving many of those diseases could itself become a target for prevention? In this conversation, Raiany Romanni-Klein, PhD, and William Mair, PhD, explain why extending healthspan, the years we spend healthy and functional, may matter far more than simply extending lifespan. They unpack the emerging science of biological aging, the ethical and economic questions surrounding longevity research, and why slowing the aging process could have profound implications for cancer, Alzheimer's disease, cardiovascular disease, frailty, and cognitive decline. They also examine the enormous societal cost of chronic disease, the burden placed on unpaid caregivers, and why aging research receives only a fraction of the funding directed toward individual age-related diseases despite its potential to influence many of them simultaneously. In this episode you’ll learn: * Why eliminating all cancers would increase life expectancy by only about 2.5 years, while targeting biological aging could have a far greater population-wide impact * The $2 trillion per year economic opportunity of slowing biological aging by just five years * What the 23-year life expectancy gap between two Boston neighborhoods just two miles apart reveals about health inequity and aging * Why aging research receives only a small fraction of the funding devoted to diseases like Alzheimer's * The difference between lifespan and healthspan, and why that distinction changes everything * The "41 is the new 40" concept and the extraordinary economic value of making people biologically younger by just one year Raiany Romanni-Klein, PhD, is a researcher and bioethicist whose work focuses on the ethics, economics, and public policy of human longevity. William Mair, PhD, is a professor at Harvard T.H. Chan School of Public Health whose laboratory studies how metabolism and nutrition influence aging, healthspan, and age-related disease. If you've ever wondered whether aging itself should become a target of medicine, or what the future of longevity science could mean for how we live, work, and stay healthy, this conversation offers one of the most thought-provoking perspectives you'll hear.

A Harvard Psychiatrist & Zen Priest on Why Relationships Are More Powerful Than Any Longevity Hack

What if one of the strongest predictors of a longer, healthier life isn't hiding in your bloodwork, but in the quality of your relationships? After following 724 people for 87 years, the world's longest-running study of adult development uncovered a finding that continues to reshape how we think about longevity. Description Robert Waldinger, MD—Clinical Professor of Psychiatry at Harvard Medical School, Director of the Harvard Study of Adult Development, Director of the Center for Psychodynamic Therapy and Research at Massachusetts General Hospital, and an ordained Zen priest—joins host Chris Wharton on The LIVING Room Podcast to explore what 87 years of research reveals about happiness, health, and living a longer, more meaningful life. Together, they unpack the study's two defining discoveries: why taking care of your physical health remains essential, and why the quality of your relationships may be just as important to healthy aging. Dr. Waldinger explains how chronic loneliness influences stress, cortisol, inflammation, and disease; why men from disadvantaged backgrounds lived an average of 10 years fewer than Harvard graduates yet reported similar levels of happiness; why wealth beyond meeting your basic needs has surprisingly little impact on long-term happiness; and how nearly 40% of our happiness is shaped by choices and habits that remain within our control. The conversation also explores meditation, worry, optimism, generosity, and practical ways to build deeper relationships in an increasingly disconnected world. Robert Waldinger is Director of the Harvard Study of Adult Development, the world's longest longitudinal study of adult life, following 724 original participants since 1938 with an extraordinary retention rate. He is a Clinical Professor of Psychiatry at Harvard Medical School, Director of the Center for Psychodynamic Therapy and Research at Massachusetts General Hospital, co-author of The Good Life, and an ordained Zen priest. His TED Talk on the Harvard Study has been viewed more than 40 million times, making it one of the most-watched TED Talks ever, and his work has been featured by leading publications including The New York Times.

Anti-Aging Brain Health Myths Most Believe: A Stanford Doctor Debunks Dementia, Brain Aging & More

Your brain starts changing earlier than most people realize. A Stanford neuroscientist explains how emerging technology could reshape the future of cognitive health. What if protecting your brain has less to do with chasing the next breakthrough, and more to do with taking action on the science we already know. In this episode of The LIVING Room Podcast, host Chris Wharton sits down with Walter Greenleaf, PhD—behavioral neuroscientist and medical technology developer at Stanford University's Virtual Human Interaction Lab—to explore what's happening to your brain as you age, why measuring cognitive health has been so difficult, and how AI, virtual reality, wearable technology, and personalized feedback systems may transform the future of prevention. Here's what you'll walk away with: * Why cognitive decline begins long before symptoms appear—and why neurodegenerative diseases like Alzheimer's develop over many years before they're detected * How virtual reality is already being used to help treat PTSD, chronic pain, addiction, and phobias—and why the brain often responds to virtual experiences as if they're real * The research from Adam Gazzaley's lab showing that specific cognitive training can improve executive function, with some adults in their 60s performing similarly to much younger adults on certain cognitive measures * Why today's AI health advice can sound convincing while still being inaccurate—and what must change before it can be trusted in healthcare * How wearables, smart glasses, and passive health monitoring could make personalized brain health recommendations part of everyday life * Why behavior change isn't just about knowing what to do—and how immediate, personalized feedback may be the missing link to lasting habits * The evidence-based habits that still matter most for protecting your brain—and why even experts struggle to consistently follow them This conversation explores where the science stands today, where it's headed next, and how evidence—not hype—can help us build healthier brains for the decades ahead.   Connect with Dr. Walter on LinkedIn: https://www.linkedin.com/in/waltergreenleaf/ [https://www.linkedin.com/in/waltergreenleaf/]  Want more?
