Migraine is still frequently discussed through the lens of “food triggers,” with chocolate, cheese, and caffeine often singled out as culprits. But the reality is far more complex. In this episode, we explore what the current evidence actually says about diet and migraine, why trigger-focused thinking can sometimes be misleading, and where dietitians can have the most meaningful impact in practice. 

Joining us today to explore this is Senior GP Headache Specialist Dr. Katy Munro. 

Dr Katy Munro was an NHS GP partner for 25 years and now works as a Senior Headache Specialist GP for the National Migraine Centre, a charity providing consultations to people with migraine, Cluster Headache and other headaches on a voluntary donation basis. 

She co-founded and hosts Heads Up podcast, Podcast of the Year 2021 finalist in the Medical Journalists Awards. 

Her book, “Managing Your Migraine”, Penguin Life Expert Series, aims to empower people with migraine to manage their condition better through understanding what is going on.

She has taught widely on migraine and has been Secretary and Council member of the British Association for the Study of Headache (BASH).

We’ve got a really interesting conversation lined up for you today, so let’s dive straight in… 

AI is increasingly being used across nutrition and dietetic practice, from meal planning and behaviour support to patient-facing tools and clinical decision-making. As these technologies develop quickly, they’re raising important questions about where they genuinely add value, where they fall short, and what this means for the future of the profession. 

Joining me today to delve into the topic is Aaron Boysen, Dietitian and CEO and Founder of Primary Care Dietitians and Tyson Tripcony, Dietitian and CEO of health app Alli. 

Tyson Tripcony is an Australian entrepreneur and operator who built a multi award-winning dietetics business from the ground up, scaled it into Australia’s largest private practice, and exited to private equity.

He’s known for saying the quiet part out loud. Tyson unapologetically challenges the status quo, pushes past professional comfort zones, and holds a simple belief: if you want different results, you don’t get them by doing what everyone else is doing. He values speed to execution, high standards, healthy competition, and a ruthless focus on what actually works in the real world.

Across his career, Tyson has operated at the intersection of healthcare and business — building teams, systems and culture designed to perform under pressure and keep improving. He cares deeply about the profession, but has little patience for complacency, credential-worship, or change resistance.

 Now, Tyson consults to health and dietetics businesses to help them achieve greater success, while also building health-tech that may just challenge the dietetics industry at large.

Aaron Boysen is a dietitian and founder of Primary Care Dietitians, the UK's largest independent provider of dietitians in NHS and private services. He's also a Clinical Safety Officer and was an NHS Topol Digital Health Fellow.

A major shift in women’s health has recently been announced: PCOS (Polycystic Ovary Syndrome) has been renamed PMOS (Polyendocrine Metabolic Ovarian Syndrome). In this episode, we unpack what’s behind the shift, whether it could help address the large number of people that go undiagnosed, and what it means for dietitians and those living with the condition — because when we change the name, the real question is: do we change care, or just the conversation? 

Joining us on the podcast today is Claire Pettitt.

A women’s health specialist dietitian with a passion for PMOS and infertility, Claire has nearly 20 years experience in healthcare, education, research, and clinical practice. Her expertise lies in nutrition and women's health, with a particular focus on Polyendocrine Metabolic Ovarian Syndrome (PMOS) and fertility nutrition where she combines academic research with applied practice, ensuring her work aligns with evidence-based principles and delivers real-world impact. Claire’s passion is supporting women to holistically manage their health through diet and lifestyle whilst optimising their relationship with food and their body. 
 
Claire has delivered specialist webinars and presentations on PCOS nutrition to many dietetic and nutrition organisations (e.g. MyNutriweb, NutritionGraduates, etc), and also lecturers on women’s health nutrition within dietetics programmes.  In addition to her dietetic and clinical contributions, Claire has recently authored a Dietetic textbook chapter on PCOS nutrition and was an invited speaker at the Fertility 2025 conference speaking on the theme of "Women's Health Nutrition: PCOS and Endometriosis,”.
   
Claire is a founding member of the British Dietetics Association’s Women’s Health and Fertility Nutrition Specialist Group, through which she has worked on many projects, including the publication of a nutrition screening tool identifying women who might benefit from dietetic support to optimise their fertility, and is currently leading a working group reviewing the evidence and writing guidelines for fertility nutrition.

Childhood obesity in the UK is not declining. Rates among schoolchildren are now the highest outside the pandemic period, despite years of policy action. At the same time, growing research into GLP-1 therapies for young people is reshaping the conversation around treatment. 

In this episode, we explore whether pharmacological innovation represents real progress for children with severe obesity, or whether it risks diverting attention from the environmental and commercial drivers at the heart of the issue. We examine the evidence, the ethics, and what a genuinely whole-systems approach could look like.

Nutrition in the Army is about making science practical in some of the most challenging conditions. Whether soldiers are training, on deployment, or operating far from everyday conveniences, dietitians and nutritionists help ensure they are fuelled, supported in recovery, and able to maintain health, performance, and resilience under pressure. 

In this episode, we explore the role of an applied nutritionist in the British Army, from shaping menus and rations to advising on supplementation and translating nutrition science into practical guidance for soldiers. 

Joining me today is Dr Shaun Chapman. Shaun is a Registered Nutritionist with the British Army, where he’s spent nearly a decade supporting the health and performance of military personnel. He 

holds a PhD in Health and Exercise Nutrition and has published extensively in the field, including scientific papers and book chapters.

For years, messages about sugar reduction and sweeteners have fuelled confusion among both the public and healthcare professionals. From safety headlines to bold claims about benefits, dietitians and nutritionists have had to cut through the noise to provide credible, balanced advice. In response, the British Dietetic Association, in collaboration with the British Nutrition Foundation and Diabetes UK, has published a joint, evidence-based position statement on low- or no-calorie sweeteners, outlining what we know, what remains uncertain, and how clinicians can guide clients while balancing safety, tolerance, and real-world dietary choices. 

In this episode, we unpack the statement in depth, exploring the context of UK sugar reformulation and “enforced consumption”, alongside emerging research on individual and combined sweetener effects. We’re joined by Duane Mellor, a registered dietitian and contributor to the statement, and 

Gabrielle Morse, an advanced dietitian specialising in neurogastroenterology, who brings a gut-focused lens. Together, they examine the evidence, navigate the nuances, and translate the science into practical advice for everyday dietetic practice.

Creatine has long been associated with gym culture, but it’s now trending far beyond strength training, appearing across social media, women’s health spaces, and everyday wellness conversations. 

Despite its popularity, the evidence is often misrepresented or overhyped, particularly around muscle gain, cognitive benefits, and mood, leaving both the public and clinicians to navigate a lot of mixed messages.

In this episode, we explore where creatine is strongly supported by evidence, where claims remain uncertain, and how dietitians can provide clear, practical guidance.
