GLP-1 is a hormone your gut releases after eating that helps you feel full and keeps blood sugar steady. No food works like a GLP-1 medication, but the foods you choose genuinely influence how much your body makes on its own. Three groups do most of the work: protein, fibre and healthy fats, along with fermented foods that nurture your gut. Here's what to eat, why it helps, and easy ways to enjoy more of it.
Great to know:
- Protein and fibre are the two nutrients most consistently linked to a stronger GLP-1 response.
- Fermentable fibre feeds gut bacteria that make short-chain fatty acids (SCFAs) these signal your gut to release GLP-1.
- Healthy fats like olive oil, avocado and oily fish play a supporting role.
- Whole, minimally processed foods make all of this easier.

Food supports your body's own GLP-1it doesn't replicate a prescription medication.
How food influences your GLP-1
Your gut is lined with specialised cells called L-cells that release GLP-1 when they sense food. They respond to protein and amino acids, to certain fats, and to the short-chain fatty acids your gut bacteria produce when they ferment fibre. In other words, what's on your plate directly shapes the signal. New to GLP-1? Start with our explainer, what is GLP-1?
Protein-rich foods
Protein is one of the most reliable triggers for GLP-1. Protein-rich meals tend to prompt more GLP-1 than meals based on carbohydrate or fat alone part of why a protein-forward breakfast can keep you satisfied for hours. Aim to include a good source of protein at every meal.

Quality protein
Our Organic Pea Protein and Whey Protein Isolate is an easy way to lift the protein in breakfasts and snacks.
Soluble & fermentable fibre
Fibre supports GLP-1 two ways: it slows digestion for lasting fullness, and importantly the fermentable kinds feed your gut bacteria, which produce SCFAs like propionate. These bind to receptors on your L-cells and prompt GLP-1 release. Most Australians fall short on fibre: adults are advised to aim for at least 25–30 g a day (around 25 g for women, 30 g for men), yet average intakes sit closer to 20 g. Build up gradually and spread it across the day to stay comfortable.

Fibre plus healthy fats |
The Healthy Chef's Everyday Greens and Probiotic + Prebiotic can help your supplement during your GLP-1 journey (prebiotic fibre feeds the gut bacteria that make SCFAs).
Healthy fats
Not all fats are equal here. Monounsaturated and polyunsaturated fats can stimulate GLP-1 secretion, whereas heavily processed fats don't appear to help in the same way. Favour whole-food fats, and use them to make vegetables and protein more satisfying.

Fermented & gut-supporting foods
Because so much of the GLP-1 signal depends on a healthy gut, foods that nurture your microbiome earn a place too. Fermented foods add beneficial microbes, while the fibre above feeds them. Think of fibre and fermented foods as a team.

Putting it together: how you eat matters
You don't need to go hard and change everything. A few simple habits do most of the work:
- Pair protein and fibre at each meal, they work better together.
- Lead with a protein-rich breakfast to set up your day.
- Choose whole over ultra-processed foods wherever you can.
- Build fibre gradually toward the 25–30 g Australian target, spread across the day.

A realistic word on expectations
Supporting your body's own GLP-1 through food is a genuinely worthwhile, sustainable habit but it isn't the same as taking a GLP-1 medication. Food works gently, with your body, over time rather than overnight. If you're on a GLP-1 medication or considering one, these foods can complement your diet—always guided by your GP, pharmacist or an Accredited Practising Dietitian.

Frequently asked questions
What foods stimulate GLP-1 the most?
Protein-rich foods and fermentable fibre are the most reliable, and combining them in a meal works best.
Does fibre really increase GLP-1?
Yes, fermentable fibre produces short-chain fatty acids that prompt GLP-1 release. Aim for 25–30 g of fibre a day.
Does protein trigger GLP-1?
Protein-rich meals tend to trigger more GLP-1 than meals based on carbohydrate or fat alone.
What's the best breakfast for GLP-1?
One built around protein and fibre, eggs with greens, or yoghurt with oats, berries and seeds. See all our breakfast recipes for GLP-1 support.
