GLP-1 receptor agonist medications, such as Ozempic®, Mounjaro® and Wegovy®, are becoming more common in Australia. They are often prescribed to support weight management and blood-sugar control.

These medications can be very effective. However, they are not a stand-alone solution. Nutrition still forms the foundation of long-term success. Nutrition remains the foundation — and seeing a dietitian can make the difference between short-term results and lasting success.

What GLP-1 medications do

GLP-1 medications mimic a natural hormone in the body. As a result, they slow digestion and help you feel fuller for longer. They also reduce appetite and improve blood-sugar control.
These changes can be helpful for weight loss, but they also mean your eating habits, nutrient intake and digestion work differently while on the medication.

Common nutrition challenges with GLP-1 use

• • Reduced appetite & smaller meals

    You might eat far less than before, which can lead to inadequate calories, protein or micronutrients if not planned carefully.

• • Digestive side-effects

    Nausea, constipation or early fullness can make it hard to meet your nutritional needs.

• • Muscle & bone loss

    Losing weight too quickly — without enough protein or resistance exercise — can result in lean muscle loss rather than just fat loss.

• • Poor diet quality

    Smaller portions can mean less variety, less fibre, and a higher risk of deficiencies over time.

• • Weight regain risk

    Without strong nutrition foundations, it’s common to regain weight once medication stops.

How a dietitian supports you on a GLP-1 journey

Working with an Accredited Practising Dietitian (APD) ensures your nutrition supports — not undermines — your medication’s effects.

A dietitian helps you:

• • Create a balanced meal plan that meets your needs even with a smaller appetite

• • Optimise protein intake to protect muscle and metabolism

• • Manage GI side-effects through strategic food choices and timing

• • Maintain nutrient adequacy and variety

• • Build sustainable habits that last long after you stop the medication

• • Collaborate with your doctor or specialist for safe, coordinated care

GLP-1 medications can be game-changers — but they work best when paired with professional nutrition guidance. A dietitian helps you lose weight safely, maintain strength, and keep results long-term while supporting overall health and wellbeing.
