    Are you interested in learning about an easy, inexpensive way to add many healthy years to your life? Something that is grounded in ancient wisdom and growing scientific research and is accessible to almost everyone. In this episode, I’m talking about diet, one of the foundational pillars of health and longevity. And I’m exploring not just what we should eat but also when we should eat and how getting these two things right can have such a positive impact on our health and how long we live. Full Episode Transcript (00:00:45) So here’s a question for you. Are you interested in learning about an easy, inexpensive way to add many healthy, active years to your life? Potentially decades! I'm not talking about some expensive new supplement or the latest fad diet. I'm talking about something that is grounded in ancient wisdom and growing scientific research. In this episode, I’m talking about food, the second foundational pillar of health and longevity — the first pillar being sleep, which I covered in the last episode and the third being movement and exercise, and I find it helpful to remember these three pillars as SLEEP, EAT AND FEET. But today is about food and I’m exploring not just what we eat but also when we eat and how getting these two things right can have such a massively beneficial effect on our health and can slow down and possibly even reverse the ageing process. (00:01:47) CAN EATING LESS OFTEN HELP YOU LIVE LONGER? So, I want to kick this episode off by focusing first on not what we should eat but when we should eat. And let's start with a fundamental principle of longevity that might surprise you: eating less often might help you live longer. Yes, you heard me right. One of the most consistent findings in longevity research in recent years, is that giving your body regular breaks from food can trigger powerful rejuvenation processes. Throughout human evolution, our bodies didn't evolve with the expectation of constant food availability. Three meals a day plus snacks is actually a very recent development in human history. Our ancestors experienced regular periods without food—sometimes by necessity, sometimes by design. Research now shows that these fasting periods are far from harmful—they actually trigger a cascade of repair and rejuvenation processes in the body. When we're constantly fed, our bodies are stuck in growth and reproduction mode. Our cells are like, yeah, life is good we’ve got plenty of readily available nutrients, let’s just kick back and relax guys. But in this euphoric state our cells can fail to spot things that are going wrong in the background – like the build up of toxins and the formation of cancerous cells. Things that, left unchecked are going to start damaging our bodies and cut our lives short. Basically, constant eating causes our cells to get a bit complacent. But when we starve our bodies of nutrients for a while we shift into repair mode. And our cells are like, hang on a minute guys, we aren’t being fed! We need to batton down the hatches and go into survival mode. And in this state, they effectively go on guard and actively hunt down any bad stuff that’s hanging around and dispose of it. Now clearly, it is a far more scientific process than this and I’ll go into some of the more nerdy stuff in a minute but this is my laymans explanation and it helps me to easily get my head around it. And this isn't just a theory. Studies across multiple species, from yeast to primates, show that controlling food intake patterns can extend lifespan. And the evidence in humans is increasingly compelling. (00:04:13) EATING LESS CALORIES AND EATING LESS OFTEN CAN HELP YOU LIVE LONGER Let's talk about why reducing calories or simply extending the length of time we go without food works at a biological level. Caloric restriction means reducing overall food intake without malnutrition and it is one of the most consistently effective anti-aging interventions across species. In the 1930s, researchers discovered that rats fed fewer calories lived significantly longer than their well-fed counterparts. Since then, similar findings have been shown in yeast, worms, flies, mice, and even preliminary studies in primates. What's remarkable is how conserved this mechanism is evolutionarily and by conserved, I mean how it has been passed down through the generations in our genes. The same pathways that respond to reduced calorie intake in a simple yeast cell appear to work in very similar ways in human cells. This suggests we're looking at a fundamental biological process that evolved very early and has been maintained across species. So why would this be? The leading theory is that when food is scarce, organisms shift resources from reproduction and growth to maintenance and repair. So as I mentioned a moment ago, It's as if the body says, "Times are tough, let's focus on surviving longer until conditions improve." Now I can guess what you might be ...

  • What is Biohacking and Can it Help You Live Longer?

    What is Biohacking and Can it Help You Live Longer?
    2025/07/02

    Biohacking. It’s a word that is becoming increasingly common. We are entering a golden age, where the AI and biotechnology revolutions are rapidly expanding our knowledge of how to prevent disease, slow down and even reverse the effects of ageing.

    Scientific breakthroughs in longevity research and personalised medicine, combined with ancient wisdom, are helping us unlock our biological potential.

    Biohacking is the art and science of taking control of your own biology and by using evidence-based approaches, we can optimize our bodies and minds.

    Sharpening our focus, improving our memory, making our bodies more resilient to disease and turning back the biological clock are all within our reach.

    Whether it's simple lifestyle modifications like intermittent fasting and sleep optimisation or advanced interventions like targeted supplementation and personalised medicine, biohacking represents a proactive approach to health and wellness that can add many healthy years to our lives.

    In this episode, I take a broad look at biohacking and how it can enable you to enhance your health and could greatly extend your life.
