Which Foods Increase GLP-1 Naturally?

Q: Which foods increase GLP-1 naturally?

Current research suggests that fibre-rich foods, green tea, cinnamon, ginger and foods rich in polyphenols may support the body's natural GLP-1 response. Fibre has the strongest evidence because it helps produce short-chain fatty acids that stimulate GLP-1 release in the gut.

Short answer: Possibly.

Emerging research suggests that some foods, herbs and plant compounds may help support your body’s natural GLP-1 response. While they don’t produce the same effects as GLP-1 medications such as Wegovy®, Ozempic® or Mounjaro®, studies suggest that certain foods may influence GLP-1 production, secretion or signalling in ways that support fullness, blood sugar regulation and metabolic health. So which foods increase GLP-1 naturally?

Scientists are particularly interested in foods rich in fibre, polyphenols and other naturally occurring compounds that interact with specialised hormone-producing cells in the gut. Although much of the research is still at the laboratory and animal stage, several foods have already shown promising results in human studies.

In this guide, we’ll explore the foods currently being investigated for their effects on GLP-1, explain what the research actually shows, and separate well-supported evidence from early discoveries.

What Is GLP-1?

GLP-1 (glucagon-like peptide-1) is a hormone produced naturally by specialised L cells in the small intestine after you eat.

Often called the body’s natural “fullness hormone”, GLP-1 plays several important roles in metabolism.

It helps:

Promote feelings of fullness after meals
Slow the rate at which food leaves the stomach
Stimulate insulin release when blood glucose rises
Reduce glucagon secretion
Help regulate appetite through the brain
Support healthy blood sugar control

Because GLP-1 acts on multiple organs—including the gut, pancreas, brain and liver—it has become one of the most important targets for treating type 2 diabetes and obesity.

Prescription medications such as Wegovy®, Ozempic® and Mounjaro® work by activating this pathway. Researchers are now investigating whether certain foods may also influence the body’s own natural GLP-1 response.

Can Food Really Increase GLP-1?

This is one of the biggest questions in nutrition research today.

The answer is yes—but with an important caveat.

No food has been shown to reproduce the powerful effects of GLP-1 medications. However, an increasing number of studies suggest that certain foods and naturally occurring plant compounds may influence GLP-1 production, release or activity.

Some appear to encourage the gut to release more GLP-1 after eating, while others may improve the hormone’s signalling pathways or help increase the sensitivity of GLP-1 receptors.

Expert commentary

Interest in GLP-1 has increased dramatically with the popularity of GLP-1 medications. However, GLP-1 is a hormone your body naturally produces after eating. Current research suggests that certain dietary fibres, polyphenol-rich foods and botanical compounds may help support this natural response as part of an overall healthy dietary pattern. While no individual food can replicate the effects of prescription GLP-1 medications, eating a varied diet rich in whole plant foods remains one of the most evidence-supported ways to support metabolic health.

Which Foods Increase GLP-1 Naturally

Foods That May Support Your Body’s Natural GLP-1 Response

Below are the foods with the most promising evidence to date, ranked according to the current strength of research.

⭐⭐⭐⭐⭐ 1. Fibre-Rich Foods (Strongest Evidence)

If there is one dietary factor consistently linked with a healthier GLP-1 response, it is fibre.

Unlike rapidly digested carbohydrates, soluble and fermentable fibres travel further through the digestive system before being broken down by beneficial gut bacteria.

This fermentation process produces short-chain fatty acids (SCFAs) such as butyrate, acetate and propionate. These compounds interact directly with the specialised L cells that produce GLP-1, encouraging the body to release more of the hormone after meals.

The recent review also highlights fructo-oligosaccharides (FOS) and other fermentable fibres as promising natural modulators of GLP-1 secretion.

In addition, studies examining different types of fibre-rich bread demonstrate that the structure and processing of foods may also influence the body’s GLP-1 response.

Foods naturally rich in fermentable fibre include:

Oats
Barley
Beans
Lentils
Chickpeas
Onions
Garlic
Asparagus
Chicory root
Jerusalem artichokes

Increasing your overall fibre intake also supports a healthier gut microbiome, creating an environment that may further enhance natural GLP-1 production.

Evidence strength: ★★★★★ Human studies, mechanistic research and a well-established biological pathway.

⭐⭐⭐⭐ 2. Green Tea

Green tea has long been associated with metabolic health, and researchers are now investigating whether it may also support the body’s natural GLP-1 response.

Green tea is rich in plant compounds called catechins, particularly epigallocatechin gallate (EGCG). These powerful polyphenols have been shown to influence several biological pathways involved in glucose regulation, inflammation and gut health.

The review identified green tea as one of the most promising natural foods currently being studied for its GLP-1-stimulating properties. Researchers believe green tea may help support GLP-1 signalling directly while also improving the health of the gut microbiome, which plays an important role in hormone production.

Although more large human studies are needed, green tea remains one of the most widely researched beverages for metabolic health.

⭐⭐⭐⭐ 3. Cinnamon

Cinnamon is more than a popular spice—it’s also one of the natural ingredients receiving increasing scientific attention for its potential effects on GLP-1.

The review highlights research suggesting that cinnamon extracts may:

Increase GLP-1 secretion
Improve GLP-1 sensitivity
Help protect GLP-1 from breakdown
Support healthy blood sugar regulation

Some human studies have reported improvements in post-meal glucose control following cinnamon supplementation, although results remain mixed and further research is needed.

Fortunately, adding cinnamon to meals is an easy way to increase flavour while following a healthy dietary pattern.

Easy ways to include cinnamon

Sprinkle over porridge
Add to Greek yoghurt
Blend into smoothies
Stir into overnight oats
Add to coffee

Evidence strength: ★★★★☆ Promising, with several human studies alongside laboratory research.

⭐⭐⭐ 4. Ginger

Ginger has been used traditionally for digestive health for centuries, but scientists are now exploring whether its natural compounds may also influence GLP-1.

The review describes research showing that 6-gingerol, one of ginger’s main active compounds, increased GLP-1 production in diabetic mice. Researchers also observed improvements in insulin secretion, glucose tolerance and blood sugar regulation.

These findings are encouraging, but most evidence currently comes from animal studies rather than clinical trials in people.

That said, ginger is an excellent addition to a healthy diet and offers several other well-established benefits, including supporting normal digestion and providing antioxidant compounds.

Simple ways to eat more ginger

Fresh ginger tea
Stir-fries
Curries
Smoothies
Soups

Evidence strength: ★★★☆☆ Mainly laboratory and animal research.

Since dietary fibre has the strongest evidence for supporting the body’s natural GLP-1 response, increasing your fibre intake can be a practical first step. If you struggle to consume enough fibre through food alone, APPETITE Fibre powder provides four types of fibre including glucomannan, psyllium husk, prebiotic inulin and ginger root.

⭐⭐⭐ 5. Quercetin-Rich Foods

Quercetin is a naturally occurring flavonoid found in many fruits and vegetables.

The review discusses research suggesting quercetin may influence GLP-1 signalling while also improving insulin sensitivity and glucose metabolism.

Rather than taking supplements, most people can obtain quercetin from everyday foods.

Good sources include:

Apples
Red onions
Berries
Cherries
Kale
Broccoli
Grapes

Although research is still developing, these foods are already recognised as valuable components of a healthy diet.

Evidence strength: ★★★☆☆ Early but promising.

⭐⭐⭐ 6. Turmeric

Turmeric contains curcumin, a bright yellow polyphenol that has attracted considerable research interest.

The review suggests curcumin may:

Support GLP-1 secretion
Reduce inflammation
Improve insulin sensitivity
Influence gut hormone signalling

However, much of the evidence currently comes from laboratory and animal studies.

Adding turmeric to meals remains an easy way to increase dietary variety while benefiting from its antioxidant properties.

Try turmeric in

Curries
Soups
Rice dishes
Roasted vegetables

Evidence strength: ★★★☆☆ Emerging evidence.

⭐⭐ 7. Fenugreek

Fenugreek seeds are commonly used in Indian and Middle Eastern cooking and have traditionally been used to support healthy blood sugar regulation.

The review discusses evidence suggesting fenugreek may enhance GLP-1 secretion and improve post-meal glucose responses.

Fenugreek also contains soluble fibre, which may contribute to its beneficial metabolic effects.

Although results are encouraging, further human studies are needed.

Evidence strength: ★★☆☆☆ Emerging evidence.

Shop Fibre Supplements

⭐⭐ 8. Berberine

Berberine is a naturally occurring plant compound found in several medicinal plants.

The review highlights berberine as one of the most extensively researched natural compounds affecting GLP-1 pathways.

Studies suggest berberine may:

Increase GLP-1 secretion
Improve insulin sensitivity
Support healthy blood sugar regulation

However, berberine is not a food and can interact with prescription medications. It should only be taken under the guidance of a healthcare professional.

Evidence strength: ★★★★☆ Strong mechanistic evidence, but not suitable as a general food recommendation.

Why Fibre Still Comes Out on Top

Although many individual foods and plant compounds are being investigated, one message stands out from the research:

A high-fibre dietary pattern is likely to have the greatest overall impact on your body’s natural GLP-1 response.

Fibre doesn’t simply provide one active ingredient. It supports GLP-1 through several complementary mechanisms by:

Feeding beneficial gut bacteria
Increasing production of short-chain fatty acids
Slowing digestion
Supporting healthy blood sugar responses
Helping you feel fuller for longer

This is one reason diets rich in vegetables, legumes, whole grains and other fibre-rich foods are consistently associated with better metabolic health.

FULLNESS BLOOD SUGAR DIGESTION

When beneficial bacteria ferment certain fibres, they produce short-chain fatty acids (SCFAs) such as acetate, propionate and butyrate. These compounds stimulate specialised L cells in the intestine, encouraging the release of GLP-1.

This helps explain why foods that nourish the microbiome may also support healthy appetite regulation.

Examples include:

Onions
Garlic
Leeks
Chicory root
Asparagus
Oats
Barley

Key Takeaway

✔ Focus on your overall dietary pattern rather than one “superfood”.

✔ Fibre-rich foods, polyphenol-rich foods and fermented foods all contribute to a healthy eating pattern.

✔ No individual food works like a GLP-1 medication, but many can form part of a balanced diet that supports overall metabolic health.

The Bottom Line

Research into natural ways to support GLP-1 is expanding rapidly. Foods rich in fibre, along with green tea, cinnamon, ginger and other plant compounds, show promising potential to influence the body’s natural GLP-1 response.

However, it’s important to keep expectations realistic. Most of these foods do not work in the same way or to the same extent as prescription GLP-1 medications, and much of the evidence is still emerging.

The strongest evidence continues to support eating a varied, fibre-rich diet that nourishes the gut microbiome and promotes overall metabolic health.

What this study DOES show

✔ Certain foods contain compounds that may influence GLP-1 secretion.

✔ Many are naturally high in fibre and polyphenols.

✔ Most also support overall dietary quality.

What this study DOESN’T show

✘ That any food works like Ozempic.

✘ That one food alone increases GLP-1 enough to cause weight loss.

✘ That everyone will respond the same way.
