  • Why Diets Don't Work: The Science of Appetite | Ep. 7 (ft. Dr. Harriët Schellekens)

    Why Diets Don't Work: The Science of Appetite | Ep. 7 (ft. Dr. Harriët Schellekens)
    Feb 12 2026
    Hungry all the time? Struggling with weight management? Wondering if those GLP-1 drugs everyone's talking about are right for you? Dr. Harriët Schellekens, senior lecturer in Anatomy and Neuroscience at UCC and leading expert on the hunger hormone ghrelin, joins us to unpack the complex biology of appetite, weight, and why willpower alone isn't the answer. From gut hormones to microbiome signaling, Harriët explains how your body decides when you're hungry, why ultra-processed foods hijack your brain's reward system, and how your gut bacteria might actually be driving your food cravings. If you've ever felt like your biology is working against you, this episode will help you understand why - and what you can actually do about it. Topics covered: What GLP-1 drugs actually do - and who they're really for The hunger hormone ghrelin and how it drives food intake Why obesity is a disease, not a lifestyle problem The pre-digestive vs. post-digestive mismatch in ultra-processed foods How high-fat, high-sugar foods create a "false promise" in your gut Sugar substitutes: the good, the bad, and the gut-friendly How your gut microbiome influences weight gain and food preferences Why crash diets backfire (and what to do instead) The role of stress, cortisol, and emotional eating Early-life food exposure and how it shapes lifelong eating habits Probiotics, prebiotics, and targeting the microbiome for better appetite control Practical tips for parents navigating kids' diets and food choices The bottom line? Your food choices aren't just about willpower - they're about biology. Understanding how your gut, brain, and microbiome communicate can help you make better decisions, break unhealthy cycles, and stop fighting your own body. Don't eat less. Eat better.

  • What Drives Brain Health: The Surprising Science of Gut-Brain Health | Ep. 5 (ft. Dr. Kieran Rea)

    What Drives Brain Health: The Surprising Science of Gut-Brain Health | Ep. 5 (ft. Dr. Kieran Rea)
    Dec 11 2025

    If you have been trying to make sense of what truly supports brain health, this episode is worth setting time aside. Barry Skillington is joined by Dr Kieran Rea, Atlantia’s Scientific Director, who brings years of experience across neuroscience, clinical trial design and the microbiota gut-brain field. Ciarán has led research teams in academia and industry, managed clinical trial portfolios in therapeutic areas such as neuroscience and immunology, and overseen translational work from early characterisation models through to human trials. Together, they unpack: ● Why so many people chase quick fixes, and why they rarely solve the root problem. ● How sleep, stress, exercise and routine drive mental clarity more than supplements ever can. ● What the gut–brain axis actually is, and how our microbiome signals to the brain through chemical pathways and the vagus nerve. ● Why digestion, meal timing, and even chewing influence nutrient absorption and energy. ● What really changes as the brain ages, and what we can do to keep it sharp throughout life. #StraightTalkingScience #BrainHealth #CognitiveFunction #GutBrainAxis #Microbiome #MentalWellbeing #HealthyAgeing #StressScience #SleepHealth #ExerciseScience #ClinicalResearch #AtlantiaClinicalTrials

  • How Does Food Impact Everyday Mental Health | Straight Talking Science Ep. 2 (ft. Prof. Ted Dinan)

    How Does Food Impact Everyday Mental Health | Straight Talking Science Ep. 2 (ft. Prof. Ted Dinan)
    Sep 23 2025

    Our guest in this episode is Prof. Timothy Dinan, Emeritus Professor of Psychiatry and a Principal Investigator in the Alimentary Pharmabiotic Centre at University College Cork (UCC). Prof. Dinan has built a distinguished career in psychiatry and neuroscience, making major contributions to uncovering how gut microbiota influence mental health.

    In this episode, we explore the gut–brain connection and the impact of food & nutrition on mental health, showing how lifestyle choices shape both mental well-being and ageing.

    He explains why stress is a major risk factor for anxiety and depression, highlights the power of the Mediterranean diet, fermented foods and Fish (EPA & DHA), and cautions against excess red meat, alcohol and drug use. We discuss why vigorous, weight-bearing exercise is essential for muscle strength, longevity and mental well-being, why most nutrients should come from whole foods rather than supplements, and how a positive attitude can dramatically improve resilience and quality of life.
