GLP-1 nutrition support Australia

Nutrition support during Mounjaro or GLP-1 care.

If your appetite, digestion or energy has changed while using a prescribed GLP-1 medication under medical supervision, it can be hard to know what to eat. This guide keeps things simple: protein, fibre, fluids, food tolerance and nutrient gaps.

We do not provide medication advice, prescribing advice or access to prescription medicines. We support the nutrition layer around your medical care.

A simple starting point

If eating has become harder, you do not need a complicated plan.

Many people do best with a calmer, simpler approach. Start by understanding what has changed, then build meals around the nutrients that matter most.

Some people feel full quickly. Some feel nauseous. Some become constipated. Others feel flat, notice hair shedding, or realise they are eating far less protein than before.

The answer is not always to add more rules. Often, the first step is to make smaller meals more nourishing and easier to tolerate.

If symptoms are severe, persistent or worrying, speak with your medical team. If the question is “how do I stay nourished while my appetite is lower?”, that is where nutrition support can help.

What may need attention

Common food and digestion changes to watch.

These are general nutrition considerations only. Use them as a guide for what to notice, not as a replacement for medical advice.

Nausea or low appetite Try smaller meals, slower eating and lighter protein options such as yoghurt, eggs, soups, smoothies, fish, tofu or lean meats.
Constipation Look at fluids, fibre type, movement and food volume. Increase fibre gradually and seek medical advice if constipation is painful, severe or ongoing.
Reflux or bloating Meal size, eating pace and food timing can matter. Some people find large, rich, spicy or carbonated foods harder to tolerate.
Loose stools Keep meals simple, prioritise fluids and electrolytes where appropriate, and speak with your clinician if symptoms persist or worsen.
Fatigue or weakness Review total food intake, protein, hydration and key nutrients such as iron, B12, magnesium and vitamin D.
Hair shedding Consider protein consistency and nutrient status, especially iron, zinc, B vitamins, vitamin D and essential fats.
When to get medical advice

Some symptoms should not be managed with food changes alone.

Nutrition can help with meal structure, tolerance and nutrient coverage. It cannot assess medication safety, diagnose side effects or replace your medical team.

Seek medical advice urgently for severe or persistent abdominal pain.
Seek help for persistent vomiting, dehydration, fainting or inability to keep fluids down.
Speak with your clinician for severe constipation, blood in stool, black stools or severe diarrhoea.
Speak with your medical team about mood changes, pregnancy concerns, contraception questions or anything that feels unusual or worrying.
What to focus on first

Smaller meals can still be nourishing.

If your intake has dropped, your meals may need to become more intentional — not more complicated.

Protein Start meals with a realistic protein source before you become too full.
Fibre Use gentle fibre from foods you tolerate, such as cooked vegetables, oats, chia, psyllium, berries or legumes.
Fluids Low appetite can reduce drinking too. A simple hydration rhythm across the day can help.
Nutrients Prioritise iron, B12, folate, zinc, magnesium, calcium, vitamin D and essential fats where relevant.
Where to start

Choose the simplest next step.

You do not need to know exactly what you need before reaching out. Start with the option that feels most relevant.

Common questions

Questions people often ask when appetite or digestion changes.

These answers are nutrition-focused. Medication questions, dose changes, prescribing, access, pricing and side effect management should be discussed with your doctor, specialist or pharmacist.

What helps nausea from a nutrition perspective?

Some people find smaller meals, slower eating, lighter meal choices and simple protein foods easier to tolerate. Persistent nausea, vomiting or signs of dehydration need medical review.

Can eating less contribute to constipation?

Yes. When food volume, fluid intake, fibre intake and movement all reduce, bowel habits can change. Severe, painful or ongoing constipation should be reviewed by a clinician.

What can I eat for constipation when my appetite is low?

Start with fluids, gentle fibre and regular movement. Cooked vegetables, oats, chia, psyllium, berries, legumes and soups may help if tolerated. Increase fibre gradually rather than suddenly.

What foods are easier to tolerate when I feel full quickly?

Many people do better with smaller, protein-focused meals such as Greek yoghurt, eggs, soups, smoothies, fish, tofu, cottage cheese, legumes or lean meats. The best option depends on your symptoms and tolerance.

What foods should I avoid if nausea, reflux or bloating is worse?

There is no one-size-fits-all banned-food list. Large meals, fried foods, alcohol, carbonated drinks, spicy foods, rich desserts or eating too quickly can be harder for some people. The aim is to notice your triggers and replace them with more tolerable, nutrient-dense options.

Why might I feel tired when my appetite is lower?

Fatigue can be linked with low total intake, low protein, dehydration, reduced carbohydrates, poor sleep or nutrient gaps. If fatigue or weakness is ongoing, speak with your medical team and consider whether nutrition testing may be useful.

Can low intake contribute to hair shedding?

Hair shedding can be influenced by rapid weight change, low protein, low iron, zinc, B vitamins, vitamin D or overall under-eating. If hair loss is sudden, significant or concerning, speak with your healthcare provider.

Is this medication advice?

No. This page does not provide advice about Mounjaro, tirzepatide, Ozempic, Wegovy, Saxenda or any other prescription medicine. It provides nutrition education for people already under medical supervision. Medication questions belong with your doctor, specialist or pharmacist.

Should I choose a strategy chat or testing first?

If you are unsure, start with the free 15-minute strategy chat. If your main concerns are nutrient gaps, fatigue, low appetite, hair changes or protein planning, the Complete Nutritional Blueprint may be a useful testing pathway to consider.

Does Wellbeing George prescribe or supply Mounjaro?

No. Wellbeing George Nutrition does not prescribe, supply, sell, advertise, recommend or facilitate access to Mounjaro or any prescription-only medicine. Medication questions belong with your doctor, specialist or pharmacist.
