Meet Annaleise

Annaleise Collier, specialist dietitian for digestive health, metabolic health and eating disorders, available via telehealth across Australia

I'm an Accredited Practising Dietitian with over eight years of clinical experience. I see adults for digestive health, metabolic health, and the full spectrum of eating concerns, from disordered eating through to diagnosed eating disorders.

My approach is thorough and collaborative. I consider the whole picture: your physiology, your history, and the reality of what it's actually like to be in your body day to day. Where relevant, I work alongside your GP, psychologist, or other clinicians involved in your care.

I trained at the University of Wollongong and worked as a clinical dietitian at the Prince of Wales Hospital in Sydney for seven years. I then spent two years as the in-house dietitian at Bondi Doctors and Double Bay Doctors, two GP practices in Sydney's Eastern Suburbs, before moving into solo private practice. I hold the ANZAED Credentialed Eating Disorder Dietitian designation, the specialist credential for eating disorder clinicians in Australia and New Zealand.

Most of the work I do isn't about prescribing a plan. It's about understanding what's going on, building something that fits the life you actually live, and giving you a clearer way to interpret what your body is doing.

When you're ready, I'm here.

  • Most of the people I see arrive after a long stretch of trying to sort things out on their own. Symptoms that haven't resolved with general advice. Patterns around food they've tried to fix on their own. A sense that something is off in the body, with no clear name for it yet.

    The work I do isn't about prescribing a plan and sending you on your way. It's about understanding what's actually going on clinically, practically, and in the context of your life and building something from there that you can sustain.

  • I see adults typically from their late teens onward, across four broad areas:

    Digestive health. IBS, IBD, coeliac disease, SIBO, reflux, bloating, constipation, diarrhoea, and the kinds of complex or overlapping gut presentations that don't fit neatly into one diagnosis.

    Metabolic health. Insulin resistance, PCOS, type 2 diabetes, perimenopause-related shifts, and cardiometabolic risk. I work with what your body is doing, your symptoms, bloodwork, and the underlying physiology.

    Disordered eating. Not every difficult relationship with food meets a clinical threshold and that doesn't make it less real. If eating is governed by rules, guilt, or a persistent sense of doing it wrong, that's worth taking seriously.

    Eating disorders. Eating disorders ask a lot of the people living with them. I work with adults across the full spectrum of presentations: anorexia nervosa, bulimia nervosa, binge eating disorder, ARFID, and other specified eating disorders. Dietetic support is a core part of treatment, not an afterthought. If you're already working with a therapist or doctor, I'll work alongside them.

    These areas overlap more often than they're usually treated. Many of the people I see are dealing with two or three at once. A digestive presentation alongside a difficult relationship with food, or metabolic concerns that have been complicated by years of restriction. I work with the whole picture rather than treating each thread in isolation.

  • Dietetic care is often most useful as part of a wider treatment picture. Where you're already working with a GP, psychologist, psychiatrist, gastroenterologist, endocrinologist, or other clinician, I'll communicate with them, with your consent, to make sure we're moving in the same direction.

    For eating disorder care specifically, I work within a multidisciplinary model. If you don't yet have a therapist or GP involved and you need one, I can help you find appropriate referrals.

  • I'm an Accredited Practising Dietitian (APD) with Dietitians Australia. I hold the ANZAED Credentialed Eating Disorder Dietitian designation, the specialist credential for eating disorder clinicians in Australia and New Zealand. I'm also a Nerva-trained clinician — Nerva is an evidence-based gut-directed hypnotherapy program for IBS.
