Past, Present, and Future of “Biological Aging” with Dr. Fitzgerald

Team DrKF sat down with Dr. Fitzgerald to pose some questions about the “state of the state” of longevity research, current controversies and future directions, and where she sees her work fitting into it. When it comes to defining and using measures of biological age, where does the science currently stand? To understand where we currently stand, and why changes are afoot, we have to first consider where we’ve come from. When Steve Horvath at UCLA released the first epigenetic biological age clock in 2013 it marked the entry of longevity medicine into the mainstream (referred to as biogerontology in science, anti-aging medicine in some clinical circles).

Reducing Senescent Cell Accumulation for Enhanced Longevity with Dr. Greg Kelly

Targeting Senescent Cells? Dose and Timing Matters – with Dr. Greg Kelly

I’m thrilled to welcome you to a truly fascinating discussion on the cutting edge of longevity medicine. In this episode, I sit down with the brilliant Dr. Greg Kelly to explore the complex world of cellular senescence and its profound implications for our aging process. We delve into the challenges of identifying these aging cells and the exciting research that’s paving the way for more accurate biomarkers. I’m particularly excited to share with you Dr. Kelly’s insights on how simple lifestyle changes, such as incorporating regular exercise and mindful caloric intake, can significantly reduce the accumulation of senescent cells. We also discuss some groundbreaking interventions, including the use of senolytic agents like quercetin, dasatinib, and piper longumine, and how they’re revolutionizing our approach to longevity.

Metabolic Engineering: The Science Behind Staying in the Zone with Dr. Barry Sears

Dr. Barry Sears (of Zone Diet Fame) on Lifetime Metabolic Health and Sourcing Omega-3s

In today’s episode, I’m thrilled to speak with Dr. Barry Sears, the creator of the Zone Diet, an approach that has not only topped bestseller lists multiple times but has also profoundly impacted nutritional practices really across the world. We dive into his transition from cancer research to nutritional science, focusing on how diet regulates the key areas of inflammation and hormonal balance. Dr. Sears shares insights from his groundbreaking work, exploring the balance of macronutrients and the pivotal role of omega-3 fatty acids and polyphenols. His contributions have revolutionized how we understand diet’s impact on health, offering valuable strategies for managing chronic diseases and optimizing wellness globally. You’ll find many clinical pearls in this conversation. Join us as I uncover the science and stories behind this influential dietary philosophy with this legend of nutrition and wellness. ~DrKF

processed foods

Ultra-Processed Foods Spell Disaster for Longevity

Of course we always say “shop the perimeter” of your grocery store, and skip buying anything with industrial ingredients you wouldn’t normally find in your kitchen. Avoid added sugars, colors, preservatives, synthetic vitamins like folic acid… and avoid additives like MSG and carrageenan. Even if these are labeled organic and especially if they are not. Here’s why:

medical research into spermidine

Spermidine & other polyamines: Important players in longevity? Yes… with a few caveats

As the name implies, spermidine was first characterized in sperm, and while there is a high concentration present in semen (and it appears important for fertility), it’s everywhere- in all eukaryotic cells. In fact, wind the evolutionary clock back to the earliest endosymbiotic happenings, you’ll find spermidine and the broader family of polyamines on center stage, playing a central role in the development of… life. Indeed, bacteria, archaea and plants (and even viruses) all rely on polyamines. These facts alone illustrate the obvious: polyamines are important. Attribution for the discovery of spermine (the polyamine metabolite of spermidine) is given to Anton Leeuwenhoek, the father of microscopy, in 1678.

AI, Digital Twins, and the Future of Personalized Medicine Interventions with Dr. Nathan Price

AI, Digital Twins, and the Future of Personalized Medicine Interventions with Dr. Nathan Price

I’m beyond thrilled to share this mind-blowing conversation with Dr. Nathan Price, Chief Scientific Officer of Thorne HealthTech and author of The Age of Scientific Wellness. Imagine harnessing AI to predict outcomes of our functional interventions (diet, supplements, lifestyle) by implementing a “digital twin” model that is populated with all of your patient’s bio data. Being able to test the response of our treatments (and importantly, the synergistic response of multimodal interventions! It’s heady stuff, but amazingly, it is where we are headed today. Dr. Price illuminates the incredible potential this technology brings for personalized evidence-based medicine in nutrition, tailoring interventions based on microbial markers, and addressing lifestyle changes for Alzheimer’s prevention. The podcast is a captivating exploration of cutting-edge concepts and provides a glimpse into the exciting future of healthcare. I was wowed by my convo with Nathan and can’t wait to start kicking the tires on this baby. I know you’ll feel the same.

Decoding Aging: The Science Of Cellular Rejuvenation With Dr. Vittorio Sebastiano

Decoding Aging: The Science Of Cellular Rejuvenation With Dr. Vittorio Sebastiano

It was a career-defining (and perhaps life changing) moment when Dr. Vittorio Sebastiano, a reproductive biologist by training, realized that because we are able to create life, that same body of information could be harnessed to create youth – that is, radically reverse our biological aging process to a younger time point without losing cellular identity. In 2014, he and his lab began unpacking this epiphany. They made the radical decision to conduct their investigations in human cells and tissue rather than in rodents, with the expectation that such a start would be a better bridge to human clinical trials. Flash forward a decade and Dr. Sebastiano and his team stand poised to begin trials in humans. Dr. Sebastiano is, in my opinion, one of the most extraordinary scientists in the longevity space today who flies under the radar of most of us in functional medicine.
