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.

Expert witness work sits at the intersection of clinical care and the legal system. When care is called into question, dietitians may play a key role in understanding what happened, why, and/or what support is needed moving forward.

In this episode, we explore the role of the expert witness dietitian, from reviewing complex cases to presenting clear, objective nutrition evidence to the court.

Joining Kate today is Rebecca McManamon, Consultant Dietitian and Expert Witness, who shares insights from her work across clinical negligence and personal injury cases, and offers practical reassurance for clinicians navigating this often misunderstood space.

Rebecca McManamon is an experienced dietitian with a background spanning NHS and private practice, across both community and inpatient settings. Her work has covered a broad range of specialities, including diabetes, oncology, weight management and nutrition support.

Since 2014, she has delivered private dietetic services specialising in neurological conditions, alongside her work as an editor, writer, and honorary lecturer on the University of Hull’s dietetics programme.

Rebecca is also an established dietetic expert witness, with over eight years’ experience producing multiple reports each month to the courts. She has completed expert witness training with Bond Solon which she is now using in preparation for accreditation from the University of Aberdeen.
