Fiona's mission is to empower health professionals to adopt weight neutral practice by providing support and training in how and why to do so. In short, she wants to destroy the perception and practice of 'dietitian as food police.'

As an Advanced Accredited Practising Dietitian and university lecturer in nutrition and dietetics, she values nourishment, autonomy, authenticity and evidence based practice. Her academic research areas are dietetic private practice benchmarking, interprofessional learning and HAES integration into dietetics. A love for research and presenting has led Fiona into presenting professional development workshops for HAES integration into clinical practice since 2013. Fiona has more than a decade of academic work (unit coordination, lecturing, tutoring, marking, research assisting) under her belt and has been employed by Queensland University of Technology (QUT), Central Queensland University (CQU) and the University of the Sunshine Coast (USC). Fiona has also reviewed submissions for peer-reviewed academic journals including Appetite and Fat Studies Journal.

After graduating from dietetics, Fiona initially spent three years as a clinical dietitian at The Wesley Hospital, Brisbane, working in a wide range of clinical areas in addition to coordinating and practising in The Wesley Hospital’s dietetic outpatient clinic, Dietitians Wesley. She also built a successful private practice, NutritionSense Allied Health, at Taringa in Brisbane from 2008 before selling it in 2014. Much of her private practice work was with chronic dieters with whom she frequently used the non-diet approach.   

Fiona’s PhD research findings have cemented her resolve that weight neutral approaches should be part of every clinician’s skill set and her research continues to inform the professional development workshops and training she provides through Health, Not Diets ( She is the author of two non-diet approach guidebooks for health professionals and developed the Non-Diet Approach Model, which operationalizes the Health at Every Size (R) principals for clinical practice.  You can read Fiona's  full PhD thesis here.

Fiona was awarded the 2017 and 2020 Dietitians Australia Research Awards at the Australia and New Zealand Association for Eating Disorders (ANZAED) conferences and the 2007 Queensland Meals on Wheels Nutrition Award, served as an elected member of the Dietitians Association of Australia (DAA) Queensland Branch Executive from 2008-2010, and held the position of President for the Association for Non-Diet Approach Research Inc from 2013-2016. She held the position of Vice President International for the Association for Size Diversity and Health 2016-2018 term and is the co-chair of the HAES Australia Governance Committee.  Fiona is also the current administrator for the Society for Australian Independent Dietitian-Nutritionists (AIDNSoc). 

Fiona has great enthusiasm for demolishing weight biased research and overusing food and eating metaphors in everyday life.
