Eat these 5 foods to naturally boost GLP-1 and support healthy weight loss
GLP-1 has become one of the most talked-about hormones in health and weight loss, largely thanks to medications like Ozempic® and Wegovy®.
But what many people don't realise is that your body has been producing GLP-1 naturally your entire life.
Every time you eat, specialised cells in your small intestine release a hormone called GLP-1 (glucagon-like peptide-1). This remarkable hormone acts as one of your body's natural appetite regulators.
It signals to your brain that you've eaten enough, slows the rate at which food leaves your stomach, helps regulate blood sugar levels and supports healthy insulin release.
In simple terms, GLP-1 helps you feel satisfied after eating instead of constantly thinking about your next meal.
The new generation of weight loss medications work by mimicking or enhancing the action of this hormone.
Because they remain active in the body for much longer than your own naturally produced GLP-1, they create a much stronger effect on appetite and fullness. That's why many people taking these medications report feeling full after just a few bites of food.
The exciting news is that while food won't produce the same powerful effect as medication, the foods you eat every day can encourage your body to release more of its own natural GLP-1.
By consistently eating the right foods, you can support your body's built-in appetite control system, helping you stay fuller for longer, reduce cravings and make weight loss feel more manageable.
Why GLP-1 matters for women over 30
As we move through our 30s and 40s and beyond, changing hormones can make appetite regulation more difficult. Falling oestrogen levels may increase hunger, encourage fat storage around the abdomen and reduce insulin sensitivity.
Many women notice they feel hungrier than they used to or struggle to feel satisfied after meals.
Supporting your body's natural GLP-1 response won't magically melt away belly fat, but it can make healthy eating much easier. When you're genuinely satisfied after meals, you're less likely to snack, overeat or experience the blood sugar highs and crashes that leave you searching for something sweet an hour later.
1. Fibre-rich foods: the number one nutrient for natural GLP-1
If there is one nutrient that deserves far more attention, it's fibre.
Most adults consume well below the recommended daily intake, yet fibre may be one of the most powerful nutrients for supporting your body's natural appetite hormones.
When you eat fibre, something fascinating happens. Unlike sugar or refined carbohydrates, fibre isn't fully digested in your small intestine. Instead, it travels to your large intestine where it becomes food for your beneficial gut bacteria.
As these bacteria ferment fibre, they produce compounds called short-chain fatty acids. These compounds help stimulate specialised L-cells in the gut to release more GLP-1.
In other words, eating fibre doesn't just fill your stomach. It actually communicates with your gut microbiome, which then sends signals encouraging your body to produce more of its own appetite-regulating hormones.
Fibre also slows digestion, helping food move more gradually through your digestive system. This means you stay fuller for longer, your blood sugar remains steadier and you're less likely to experience energy crashes or intense cravings.
Excellent sources include:
- Broccoli
- Brussels sprouts
- Spinach
- Kale
- Cauliflower
- Cabbage
- Chia seeds
- Flaxseeds
- Lentils
- Chickpeas
- Beans
- Oats
- Berries
Aim for at least 25-30 grams of fibre each day, increasing gradually and drinking plenty of water.
P.S our GUT formula is a 3 in 1 formula combining pre biotics, pro-biotics and collagen and gives you 5g of fibre per serve. You can see the product and read reviews in our shop and this is a game changing product
2. Protein: the nutrient that tells your brain you've eaten enough
Protein is consistently shown to be the most satisfying macronutrient.
When protein reaches your digestive tract, it stimulates the release of several hormones involved in fullness, including GLP-1.
It also helps preserve lean muscle, which becomes increasingly important during perimenopause and menopause as muscle naturally declines with age.
Eating adequate protein may help:
- Reduce hunger between meals
- Support stable blood sugar
- Reduce late-night snacking
- Maintain muscle while losing fat
- Keep you feeling satisfied for longer
Aim to include around 25-35 grams of quality protein at every main meal.
Great choices include eggs, Greek yoghurt, chicken, fish, tofu, cottage cheese, legumes and high-quality protein powders.

3. Healthy fats help keep GLP-1 working for longer
Healthy fats have unfairly received a bad reputation over the years.
In reality, fats slow stomach emptying, helping you stay satisfied long after your meal has finished. Research also suggests healthy dietary fats contribute to the release of GLP-1 following meals.
Adding healthy fats also helps your body absorb important fat-soluble vitamins including vitamins A, D, E and K.
Choose foods such as:
- Avocados
- Extra virgin olive oil
- Almonds
- Walnuts
- Pumpkin seeds
- Salmon
- Sardines
Because fat is energy dense, a moderate serving is all you need.
4. Fermented foods support the gut bacteria that influence GLP-1
Your gut microbiome plays a surprisingly important role in metabolism.
The trillions of bacteria living inside your digestive system help determine how efficiently you digest food, regulate inflammation and even influence hunger hormones.
Eating fermented foods regularly helps support a diverse and healthy microbiome.
Good options include:
- Natural yoghurt
- Kefir
- Sauerkraut
- Kimchi
- Miso
Think of these foods as helping create the healthiest possible environment for your gut to function at its best.
5. Resistant starch: the carbohydrate that behaves like fibre
Not all carbohydrates behave the same way.
When foods such as potatoes or rice are cooked and then cooled, some of their starch changes into resistant starch.
Rather than being rapidly digested, resistant starch reaches the large intestine where, just like fibre, it feeds beneficial gut bacteria.
This process produces more short-chain fatty acids that may encourage GLP-1 release while also improving insulin sensitivity.
Great sources include:
- Cooked and cooled potatoes
- Cooked and cooled rice
- Green bananas
- Lentils
- Beans
It's one of the simplest nutrition hacks you can add to your meals.
Foods that may work against healthy GLP-1 signalling
Just as some foods support your body's natural appetite hormones, others make it harder for your body to regulate hunger.
Highly processed foods are often rapidly digested, causing sharp rises in blood sugar followed by equally sharp crashes. These swings can leave you feeling hungry again very quickly.
Try limiting:
- Sugary drinks
- Lollies
- Cakes
- Biscuits
- White bread
- Highly processed breakfast cereals
- Chips
- Fast food
- Ultra-processed snack foods
These foods are typically low in fibre and protein and are designed to be easy to overeat. While they don't "turn off" GLP-1, they generally don't stimulate the same beneficial satiety response as whole foods rich in fibre, protein and healthy fats.
The popularity of GLP-1 medications has shone a spotlight on just how important this hormone is for appetite control and weight management. But long before these medications existed, our bodies were already producing GLP-1 naturally after every meal.
While no food can replicate the powerful effects of prescription GLP-1 medications, building your meals around fibre-rich vegetables, quality protein, healthy fats, fermented foods and resistant starch gives your body the best opportunity to activate its own natural appetite-regulation system.
Combined with regular movement, strength training, quality sleep and stress management, these foods can help you feel fuller, reduce cravings, support healthy blood sugar and make sustainable weight loss feel much easier.
The real secret isn't finding one miracle food. It's consistently eating in a way that allows your body's own hormones to work the way they were designed to.
