Hi, I’m Rosie Mansfield a Holistic Nutritionist & Holistic Personal Trainer.

For over 10+ years, I have been helping people improve their health through a realistic, sustainable, and deeply holistic approach to nutrition and movement.

My passion for nutritional medicine began at just 14 years old, following my own experience with a mystery illness that the traditional medical system had stopped investigating. Meeting a Nutritionist who truly listened changed the course of my life. Through food, compassionate care, and a holistic approach to healing, I discovered not only the transformative power of nutrition, but also the profound impact of feeling seen, supported, and given hope.

That philosophy is at the heart of everything I do today. I believe health should feel sustainable, enjoyable, and achievable - because what’s the point of advice that can’t actually be maintained? I embrace the 80:20 approach to eating (because a little indulgence is good for the soul), draw inspiration from the longevity principles of Blue Zone living, and believe the mind and body are deeply interconnected.

I specialise in supporting people with complex or “mystery” chronic health issues, as well as neurodivergent food therapy. My approach is thorough and investigative, focusing on uncovering the root cause of symptoms through comprehensive assessments and blood testing. I prioritise a food-first philosophy, while incorporating targeted supplementation when needed to support healing and balance.

This work is also deeply personal. Having experienced challenges including anxiety, panic attacks, and a later-in-life ADHD diagnosis, they bring both professional expertise and lived experience to their practice. Meditation became a transformative part of my own healing journey, helping calm a fast-moving neurodivergent mind and creating space for a gentler, more balanced way of living. This mindfulness-based approach is now woven into the support I offer clients, reflecting their belief that health is about far more than food alone - it’s about how people live, think, rest, and connect.

Many may also recognise me as the “Good Chef” from Good Chef Bad Chef on Australian TV, where I specialised in teaching people how to cook vegetarian meals the whole family can enjoy.

Outside of work, I can often be found diving into the ocean, walking the coastline, road cycling with friends, reading, travelling through Europe or searching for the perfect Neapolitan pizza!

Through TikTok, Instagram, Facebook, and YouTube, I share practical health advice, recipes, wellness inspiration, and glimpses into everyday life - helping others embrace a more balanced and sustainable approach to wellbeing.

Love & laughter,

Rosie Mansfield x
