GLP-1 Medication Support with a Dietitian

Why general advice tends to fall flat

Most people start a GLP-1 medication with a few lines of advice: eat smaller meals, drink water, get enough protein. None of that is wrong, but it stops short of the real questions. What do you do when you are genuinely not hungry by lunchtime? Which foods are sitting badly, and which ones are worth keeping? Are you eating enough to look after your muscle, your iron and your energy, or only enough to get by?

Those answers depend on your appetite pattern, your side effects, your health history and how you like to eat. That is why a plan built around you tends to be more useful than another general list.

Is this consult right for you?

It is probably a good fit if:

• You have been prescribed a GLP-1 medication and your appetite has dropped so far that you are not sure you are eating enough.
• Nausea, reflux or constipation are shaping what and when you eat.
• You want to look after your muscle and energy, not just the number on the scales.
• You are planning to stop, with your prescriber, and want a plan for when your appetite comes back.

Dietitians do not prescribe, and this consult is not about getting or changing a medication. Your doctor looks after that. We look after the food side, alongside them.

What happens in the consult

The consult runs for 45 minutes and costs $150. You can book it by telehealth from anywhere in Australia, or in person at our Mount Hutton clinic.

What we look at

• What a normal day of eating looks like now, and how that has changed since you started.
• When you feel hungry, when you do not, and which foods you are avoiding.
• Any side effects, and what seems to set them off.
• Your health history, other medicines and any recent blood tests you have.
• Your activity, and what you want from the next few months.

What you walk away with

• A way of eating that fits the appetite you actually have, with protein and nutrients prioritised.
• Practical changes for the side effects that are bothering you most, in the order to try them.
• A clear view of which nutrients to keep an eye on, and what to ask your GP about.
• Signs that mean something needs your doctor rather than a food change.

Where the evidence sits

Australian Prescriber, Dietitians Australia and a 2025 joint advisory from four US professional bodies all recommend nutrition support alongside GLP-1 treatment, particularly for eating enough protein and nutrients, looking after muscle, and managing side effects. In fairness, randomised trials of dietitian support alongside these medicines have not yet been done. What we offer is careful, individual advice that works with your treatment.

What Australia’s dietitians are saying

Dietitians Australia recommends that people prescribed these medicines are referred to an Accredited Practising Dietitian. In September 2026 it joined Exercise & Sports Science Australia in asking the Pharmaceutical Benefits Advisory Committee for funded dietitian and exercise physiologist support alongside treatment. Their statement says GLP-1 medications “reduce appetite and food intake, which makes it harder to get enough protein, vitamins and minerals.” This is a proposal, and nothing about Medicare funding has changed yet. You can read what the joint statement asks for.

Our guides go deeper on three common questions: getting your nutrition ready before you start, protecting your muscle and which nutrients can run low.

When it needs your doctor, not a dietitian

Please do not change or stop your medication without talking to your prescriber. If a side effect is making it hard to eat, tell them: there are often options, and we can work alongside whatever they decide.

If eating has started to feel difficult

A quieter appetite can be a relief. For some people, though, it can also make it easier to slip into skipping meals or eating less and less, or it can bring back old worries about food. If eating has started to feel like something to get through rather than something that looks after you, it is worth saying so. Ausclin also provides eating disorder support, and we will talk it through with you gently and without judgement.
