Nutrition advice that fits the life you live.
Mary-Anne's clinical philosophy is built on four principles — refined over 17 years of work with people whose health needs change with life stage, diagnosis, and circumstance.
Evidence-based
Strategies grounded in published clinical evidence and recognised therapeutic frameworks — such as the Monash University low FODMAP diet, Dietitians Australia bariatric guidelines, current MBS-aligned chronic disease guidelines, the RPAH elimination diet, Diabetes Australia guidelines and Australian Heart Foundation guidelines.
Personalised to you
Your dietary plan reflects your diagnoses, your medications, your tolerance levels, your cultural food preferences, and your life circumstances. No copy-paste plans.
Practical & sustainable
Simple, evidence-based changes that fit real family life — not restrictive rules that collapse the moment life gets busy. The plan that works is the one you can actually follow.
Compassionate & person-centred
Built across hospital, private, and aged care settings — Mary-Anne brings clinical rigour and warmth to every consultation, particularly for patients managing complex medical needs.
A broad clinical scope, delivered with depth.
Across metabolic, digestive, cardiovascular, life-stage, and complex-care nutrition — Mary-Anne provides medical nutrition therapy for the conditions most often referred from GPs.
Metabolic
Diabetes (types 1, 2 and gestational)
Carbohydrate quality and distribution, glycaemic load, weight management, and medication coordination — supporting blood sugar control across type 1, type 2 and gestational diabetes without overly restrictive diets.
Metabolic
PCOS & insulin resistance
Nutrition strategies that improve insulin sensitivity, support hormonal balance, and address weight, fertility, and menstrual concerns commonly seen in PCOS.
Cardiovascular
Cholesterol, blood pressure & fatty liver
Dietary patterns to lower LDL, manage hypertension, and reverse non-alcoholic fatty liver disease — practical changes that complement medical management.
Digestive
IBS (Monash low FODMAP-trained)
Three-phase Monash protocol — elimination, structured challenges, and personalised reintroduction — to identify triggers and restore food variety with confidence.
Digestive
Coeliac disease
Gluten-free transition for coeliac patients — establishing a strict, nutritionally complete gluten-free diet and managing cross-contamination and associated deficiencies.
Digestive
Inflammatory bowel disease (IBD)
Nutritional support for Crohn's disease and ulcerative colitis through flare and remission phases — maintaining nutritional status, managing symptoms, and addressing deficiencies.
Gut health
Food intolerances & sensitivities
Identifying triggers across salicylates, amines, glutamates, and common food additives — managing symptoms without unnecessary restriction.
Life stage
Perimenopause & menopause
Evidence-based strategies for bone density, heart health, gut health, and symptom reduction — with focus on protein distribution, carbohydrate timing, and resistance training support.
Neurodevelopmental
ADHD
Dietary support alongside stimulant medication — managing reduced appetite, weight maintenance with high-energy-high-protein strategies, and addressing food chemical sensitivities where relevant.
Weight
Weight loss including weight loss surgery
Full progression support — pre-surgery preparation, fluid/purée/soft-food phases, transition to normal textures, with strong emphasis on protein preservation and managing post-op symptoms.
Immune & inflammation
Autoimmune conditions
Nutrition strategies focused on reducing inflammation, supporting immune function, and managing the metabolic impacts of autoimmune disease and its treatments.
Older adults
Aged care & malnutrition
Hospital-grade experience in malnutrition screening, enteral feeding, and nutrient deficiency management — supporting older patients with complex medical needs.
Two named clinical pathways, each delivered in stages.
Some clinical situations need more than a single consultation — they need a structured, phased approach. Mary-Anne runs two named pathways with established clinical methodology.
Pathway 01
The Low-FODMAP three-phase pathway
For patients with diagnosed IBS — Monash University's evidence-based protocol, delivered with structure and personalisation.
- 01
Baseline elimination
Structured low-FODMAP diet for 2-6 weeks to establish symptom baseline and confirm dietary responsiveness.
- 02
Structured challenges
Systematic reintroduction of each FODMAP group to identify which triggers cause symptoms and at what threshold.
- 03
Personalised expansion
Building a long-term personalised diet that maintains symptom control while restoring food variety and meal flexibility.
Pathway 02
The bariatric surgery nutrition pathway
Comprehensive nutritional support across the full bariatric surgery journey — pre-operative preparation through long-term maintenance.
- 01
Pre-surgery preparation
Optimising nutritional status pre-operatively, building habits that support post-surgical adherence, and managing the pre-op liver-reduction diet.
- 02
Fluid, purée & soft-food phases
Structured progression through post-operative texture stages, with protein prioritisation and management of reflux, nausea, and constipation.
- 03
Transition & long-term maintenance
Return to normal textured foods with continued protein focus to preserve muscle mass — addressing intolerances and weight regain risk over time.
Nutrition that works alongside your care.
Mary-Anne's clinical scope overlaps directly with two of our pillar services. Where nutrition is part of the treatment, integration matters.
Pillar overlap
Menopause care + nutrition.
Bone density, cardiovascular risk, and metabolic changes during perimenopause and menopause are nutrition-responsive. Mary-Anne works alongside Dr Paul's menopause patients on protein distribution, resistance training nutrition, and reducing symptoms through dietary strategy.
See menopause service →Pillar overlap
ADHD care + nutrition.
ADHD stimulant medications often suppress appetite and cause weight loss; food chemical sensitivities can affect symptoms in some patients. Mary-Anne supports Rosedale's ADHD patients with high-energy-high-protein strategies and trigger management.
See ADHD service →Dietetics and GP care, under one roof.
Most dietetics happens in isolation from the GP managing the underlying condition. At Rosedale, Mary-Anne works inside the practice — same clinical record, same team, one coordinated plan.
Start with your GP.
For Medicare-rebated sessions, your GP prepares a chronic condition management plan (CCMP) — a structured consultation that confirms eligibility and sets the clinical direction.
Internal referral.
Your GP refers directly to Mary-Anne within the practice. No external paperwork; her Friday consulting day is bookable through HotDoc.
Sessions begin.
A 45-minute initial consultation assesses your needs and starts the dietary plan. Reviews are 30 minutes, scheduled at a rhythm that fits the condition being managed.
Shared clinical record.
Mary-Anne and your GP share access to one clinical record — so medication changes, lab results, and dietary progress are visible to both.
Accessible fees, Medicare-eligible.
Patients with a GP chronic condition management plan (CCMP) receive a Medicare rebate per session. Fees are confirmed at booking; no hidden charges.

Before you book.
The questions patients ask most often before their first consultation.
Do I need a GP referral to see Mary-Anne?
Not always. You can book directly as a private patient. To access Medicare rebates, you need a chronic condition management plan (CCMP) from a GP — which we can arrange in-house at Rosedale during a standard consultation.
What's the difference between an MHCP and a CCMP?
Different programs, different services. A Mental Health Care Plan supports psychology sessions (up to 10 per year). A chronic condition management plan (CCMP) supports allied health like dietetics, podiatry, and physiotherapy (up to 5 per year, shared across providers). Your GP determines which is appropriate for your situation.
Can we do sessions via telehealth?
Yes. Mary-Anne offers both in-person and telehealth consultations. Telehealth works well for follow-up reviews; initial assessments can be either, depending on the condition and your preference.
What should I bring to the first session?
If you have them: recent blood results (especially HbA1c, lipid panel, vitamin/mineral levels), a list of your current medications, your GP's chronic condition management plan (CCMP) (if completed), and any specialist letters relevant to your condition. If you don't, that's fine — bring what you have.
How many sessions will I need?
It depends on the condition. Simple symptom management may need 2-3 sessions. Structured pathways like low-FODMAP (3 phases) or bariatric surgery support extend across 6-12 months. Mary-Anne will discuss expected timelines at your initial consultation and revisit them with you over time.
My child has ADHD — can Mary-Anne help with appetite and weight on medication?
Yes. Mary-Anne has specific expertise supporting ADHD patients managing reduced appetite and weight loss on stimulant medications like methylphenidate and dexamfetamine. High-energy-high-protein strategies and meal timing can preserve growth and weight without forcing food.
