    Ep. 11 - Ozempic, Yo-Yo Diets & the Science of Weight Loss, with Dr. David Allison

    01/06/2026 | 45 mins.
    Obesity is one of the most misunderstood and emotionally charged topics in health. But what does the science actually say? Dr. David Allison is one of the world’s leading obesity researchers and biostatisticians. Today, he’s here to cut through the noise.
    A professor of paediatrics and director of the USDA Children’s Nutrition Research Centre, David has spent decades challenging assumptions in the field. His rigorous, evidence-led approach is exactly what this conversation calls for.
    He sits down with Charlie and Greg to unpack what obesity actually is, what drives it, and how to think about managing it in a way that’s realistic, compassionate, and grounded in evidence.
    Starting with the science, David explains why BMI is more nuanced than its critics suggest, and why the conceptual definition of obesity - excess body fat that impairs health or longevity - is harder to work into practice than it sounds. He walks us through what we can say with confidence about obesity’s health risks, the role of energy balance and diet composition, and why body weight tends to creep back up after dieting (with some surprisingly reassuring findings along the way).
    In the practice segment, David, Greg, and Charlie get into the practical side of weight management, including:
    •        Why higher protein intake is one of the biggest levers for body composition
    •        The case for resistance training – especially if you’re using GLP-1 medications
    •        How to evaluate diet advice using a simple evidence checklist
    •        Why the ‘dental model’ of weight management might change how you think about yo-yo dieting
    •        What to know before starting semaglutide or other obesity medications
     
    Finally, in the experience section, we turn to listener questions. We tackle navigating weight management during perimenopause and menopause, how to evaluate conflicting health claims online, and what to do about hair loss while using Mounjaro and GLP-1s.

    Ep. 10 - Debunking cognitive decline: why your brain doesn't have to slow down with age, with Dr. Tommy Wood

    18/05/2026 | 59 mins.
    Most of us assume cognitive decline is an inevitable part of getting older. But what if the science says otherwise? Dr. Tommy Wood says this is a modern health myth. His argument: if stimulated in the right way, the adult brain can stay sharp and high-functioning well into retirement age.
    A neuroscientist, performance consultant, and recent author of The Stimulated Mind, Tommy has spent his career applying the principles of brain performance to a wide range of lifestyles - from Formula 1 drivers to busy professionals. This week, he sits down with Charlie and Greg, to explore what it actually takes to keep your brain healthy and adaptable across time. 
    Starting with the science, Tommy will walk us through how the brain develops, and why being challenged through learning is good for neuroplasticity. He helps us wrap our heads around this with a helpful shorthand he calls “the 3-S Model”: Stimulus, Supply, and Support. Our guest also makes a case for freeing up “headroom”; we’ll let you find out what that means. Together, we’ll explore why cognitive decline is so often the result of a more sedentary lifestyle, and find out how to circumvent that.
    In the practice segment, Tommy, Greg, and Charlie will get into tangible exercises and small habits we can all try to improve our brain's ability to learn. Including:
    Why video games are actually good for us (31:30)
    Which physical activity sustains brain health best (35:05)
    The case for learning a language - and yes, this includes coding (38:19)
    How to stay challenged in a world where AI starts doing the thinking for us (40:55)

    Finally, in the experience section, we turn to real-life learning challenges and answer your listener questions. We’ve got a fascinating discussion on access to information in the age of the internet, and how that impacts our memory capacity. We also bring you practical answers to reconcile the enjoyment of learning new things with long-term cognitive benefits.

    Ep. 9 - Training and the menstrual cycle: the science of resistance training for women, with Dr. Lauren Colenso-Semple

    04/05/2026 | 53 mins.
    In the gym, there’s often a pattern: women on the cardio machines, men in the weights section. It's a divide that says a lot about how we think women should train, but how much of that is science, and how much is just habit?
    This week, Greg and Charlie sit down with Dr. Lauren Colenso-Semple, a researcher specialising in female physiology and strength training,to answer the question: should women train like men? Lauren is also the co-owner of the MASS Research Review, which helps bridge the gap between cutting-edge research and practical fitness strategies for coaches and trainers.

    As always, we’ll start with the science, unpacking the key biological differences between the sexes and what they actually mean for how women should train, their risk of injury, and their relationship with exercise across different life stages. From hormonal fluctuations across the menstrual cycle to the effects of menopause symptoms, we explore how the body changes and what that means for getting the most out of your training. 

    From there, we move into the practice, where Lauren, Charlie, and Greg discuss tangible ways to improve our training routines. They discuss:
    How socialisation shapes women's access to sport from an early age (19:08)
    Why resistance training is conducive to healthy aging (26:23) 
     What should we consider before pursuing Hormone Replacement Therapy? (31:52)

    Lauren walks us through what physical training can look like across different life stages, including how contraception and menopause factor into the picture. 
    Finally, in the experience section, we turn to your questions. How to get back into training post-partum? Can pilates and stretching help relieve period cramps? Are there exercises we should be prioritising to better manage our cycles? Tune in to find out. 
    While we’re here, just a note on language: throughout this episode, we use the term "women" for accessibility, but this episode makes an important distinction between gender and biological sex.

    Ep. 8 - Q&A: fat loss, cholesterol, caffeine, and beating jet lag, with Greg and Charlie

    21/04/2026 | 43 mins.
    Have you ever written to us and been waiting expectantly for your question to make the cut? Well, it's time we finally answered you. 
    This week, Greg and Charlie are back behind the mic for something a little different; a special Q&A episode. Over the course of 8 episodes, we've gathered a number of fascinating listener questions that don't always fit neatly into the subjects we cover. So today, we give four questions the spotlight they deserve, drawing on Greg's depth of knowledge and experience in the world of science.
    We cover three big themes: nutrition, caffeine, and sleep. From the basics of fat loss to the science of jet lag, Greg – or Dr. P, as we like to call him – breaks down the science, while Charlie brings the questions you actually want answered, including:
    Low fat or low carb: which is best for weight loss? (3:53)
    Can you lower cholesterol through diet alone, without taking statins? (13:26)
    How does caffeine work, and does it affect everyone's sleep in the same way? (19:07)
    What's the best way to prepare for and recover from jet lag? (And is May a good time to see the cherry blossoms in Japan?) (33:32)

    Whether you're fine-tuning your diet, navigating your relationship with coffee, or counting down to a long-haul flight, there's something in this episode for you. And if you stick around, you might just hear from our producer Lise, who may or may not be drinking an alarming amount of French press coffee every morning.

    We hope you enjoy this alternative format; and let this be your reminder to send in your questions to [email protected]. Greg's brain is officially on tap.

    Ep. 7 - Should we all be eating differently? Personalised nutrition beyond the hype, with Dr. Lucia Aronica

    06/04/2026 | 50 mins.
    We all know that eating well matters; but what does that actually mean for you, specifically? Low-fat, low-carb, mediterranean, keto, intermittent fasting… What if the reason no single diet works for everyone is because no single diet should?
    In this episode, Greg and Charlie sit down with Dr. Lucia Aronica, an epigenetics and nutrigenomics scientist at Stanford University School of Medicine, who has contributed to the DIETFITS study, one of the best-known trials in the field of personalised nutrition. 
    Lucia will break down what factors shape personalisation, and what the research really shows. We discuss the findings of the DIETFITS study, explain how individual responses vary, and break down what variables really matter for a healthy diet. We then zoom out to ask the bigger question: is there actually compelling evidence that a personalised nutrition plan beats a well-designed, healthy, generic one?
    From there, we move into our practice segment, where Lucia shares what this all means day-to-day. We cover:
    The healthy eating principles that apply to all of us, whatever our goals (21:41)
    Why testing insulin is crucial (25:06)
    Why pleasure is the key to adopt long-lasting healthy eating habits (29:21)
    Finally, in the experience section, we pick up on your questions. From the future of DNA-based nutrition to the truth about keto and your microbiome, meal timing, insulin spikes, and whether that daily tablespoon of olive oil is as good as people say, Lucia gives her take on some of the most common (and most debated) questions in nutrition today.

    Personalised nutrition is a genuinely exciting scientific territory, but at times, it can be overhyped. This episode helps you figure out what the evidence actually supports, and what practical steps you can take right now.
