<p>Today we are joined by a very special guest and dear friend of the Biohacking Girls community in Norway — <strong>Leslie Kenny</strong>, founder of Oxford Healthspan and a leading voice in the global longevity field.</p><p>Leslie has spent years studying how we can support cellular health, slow biological aging, and improve healthspan — the years we live with strength, clarity and vitality.</p><p>She is also one of the most loved speakers at <strong>Biohacking Weekend</strong>, and this year she returns to Norway for the <strong>fifth time</strong>.</p><p>In this episode we dive into one of the most talked-about molecules in longevity science: <strong>spermidine</strong>.</p><p>Spermidine is a naturally occurring compound found in many foods and is being studied for its role in <strong>autophagy</strong>, the cellular “recycling system” that helps maintain healthy cells as we age.</p><p>But there are also many misunderstandings around this topic.</p><p>In this conversation we explore:</p><p>• What spermidine actually is and why scientists are interested in it<br>• The difference between <strong>food-derived and synthetic spermidine</strong><br>• Why “more is not always better” in longevity science<br>• Why supplements should never replace lifestyle foundations<br>• How <strong>autophagy supports cellular renewal and immune resilience</strong><br>• Why longevity science needs more <strong>female-specific research</strong><br>• Spermidine-rich foods and the idea of a <strong>food-first approach</strong><br>• What Leslie is seeing right now in the global longevity field<br>• The shift away from miracle molecules toward <strong>whole-system health</strong></p><p>We also discuss the broader perspective of longevity: not about living forever, but about maintaining <strong>strength, cognitive clarity, mobility and independence as we age.</strong></p><p><strong>Links to read more:</strong></p><p><a href="https://doi.org/10.1016/j.tcb.2023.08.002"><br>https://doi.org/10.1016/j.tcb.2023.08.002</a></p><p><a href="https://doi.org/10.1080/2162402X.2022.2146855">https://doi.org/10.1080/2162402X.2022.2146855</a></p><p>If you want to learn more about longevity science, cellular health and the future of healthy aging, Leslie will be speaking live at <strong>Biohacking Weekend 2026 in Norway</strong>, 21 th and 22nd of March.</p><p>Join us for a weekend filled with inspiring talks, cutting-edge science and practical tools for optimizing health.</p><p><strong>Sign up for Biohacking Weekend 2026 here:</strong><br><a href="http://www.kongresspartner.no">www.kongresspartner.no</a></p>
