Sleep, stress and exercise: your longevity toolkit | Kayla Barnes-Lentz

Welcome to ZOE Science and Nutrition, where world leading scientists explain how their research can improve your health. The year is 2099. As you pick up your hoverboard and head towards the door, a microchip in your brain tells you it's time to eat. You knock back a fistful of multicolored pills while your AI powered robot helper ties your shoes. On your way to the cryo therapy center in your five g proof electro bubble, a thought crosses your mind. Surely, there's a simpler way. There are an estimated a 100,000 biohackers globally, and this number is growing. For many of these people, life is one long self experiment. Try new gadgets, supplements, and even surgeries, all in the pursuit of living past a 120. It's an interesting approach, but does it really work? Well, today, I'm joined by Kayla Barnes Lentz, the world's foremost female biohacker, who claims to be the world's most measured woman. We explore the lengths she goes to as she pursues her mission of living to 150. We'll also hear from Doctor Federica Amati, head nutritionist here at ZOE, a scientist at Imperial College London and author of the best selling book, Everybody Should Know This. Federica will help us explore the boundary between biohacking and science backed advice. By the end of this episode, you'll have some simple lifestyle interventions that both biohackers and scientists agree will help you live a long and healthy life. Kayla, thank you so much for joining me today. Thank you so much for having me. And, Federica, wonderful to have you as well. Always fun. So, Kayla, we have a tradition here at ZOE where we always start with a quick fire round of questions from our listeners. Are you up for that? Absolutely. Alright. And we have some very strict rules. You can say yes or no or a one sentence answer if you have to. Okay. Alright. Kayla, are you confident that you will live until you're 150? No. Are you the most measured woman in the world? Yes. Publicly measured, yes. Federica, does extending your life have to be expensive? No. Does self experimentation in science always fail? No. And finally, Kayla, what's the strangest thing you ever tried in your quest for longevity? I have removed all of my plasma from my body, and I have replaced it not once but twice now. And so that's like the plasma in your blood? Yeah. It's like an oil change for your body. Wow. This word biohacking is a term that I've heard used a lot recently. Mhmm. But to be honest, I don't think I really understand it. How would you describe what biohacking is? Yeah. I would just say upgrading the environment internally and externally. So you are using different modalities. That can be the basics that we'll get into, like nutrition and exercise, or it can be much more advanced, looking at labs and then incorporating interventions, maybe like hyperbaric, but internally …
