Katie Ryan
Simplistic Nutrition
About
Hi, I'm Katie! An Accredited Practising Dietitian with a passion for simplifying nutrition. I specialise in helping both adults and children manage IBS, coeliac disease, SIBO, functional gut disorders, and food intolerances with evidence-based, practical strategies.
After running a clinic in Brisbane, I've brought my experience to Mackay, where I now combine professional expertise with a personal, compassionate approach. As a mum, I understand the importance of finding realistic solutions that fit into busy lives, because nutrition should support your life, not complicate it. I also live with IBS myself, so I truly understand the challenges that come with digestive health.
All recommendations are guided by the latest nutrition research and best-practice care — no fads, no unnecessary supplements, just clear guidance that works for you and your family.
Approach: Compassionate, evidence-based, practical and simplified — treating each client with kindness, empathy and respect; focused on realistic strategies that fit into busy lives with no overwhelm or unnecessary restriction.
Weight Loss Approach
Evidence-based, fad-free nutrition with realistic, practical strategies tailored to the individual. No one-size-fits-all approach and no unnecessary supplements.
