9 ways to boost GLP-1 naturally

If there is a habit experts constantly recommend to support GLP-1, it gives priority to protein. Foods that include enough protein cause a strong release of the hormone, helping you feel fuller for longer. “Protein is one of the most powerful direct stimulators of GLP-1 release,” says Dr. Jean-Marc Sobchak, a doctor of naturopathy in Hook. A meal containing about 25-30 grams of protein produced significantly higher GLP-1 responses than a carbohydrate-heavy meal. It may seem like a lot, but it’s easier to achieve than you think. In short, 25-30 grams of protein can be found in three to four eggs, a 150-gram portion of fish or chicken, about 200 grams of Greek yogurt, a protein shake, or a hearty serving of tofu or tempeh.

Plant-based options can also work – for example, a bowl of lentils or beans made with whole grains. Nutritionist and author Nozempic Diet Aiming for protein at every meal is one of the simplest ways to naturally regulate appetite, says Kim Pearson. “Protein stimulates many hormones, including GLP-1,” he explains. “It also takes longer to digest, which helps keep you fuller after you eat.” Many experts recommend pre-loading protein at the beginning of the day, when most people tend to slow down. Substituting toast for eggs, choosing Greek yogurt instead of cereal or adding protein powder to smoothies can make a significant difference in energy levels and appetite.

Fiber may not be the most palatable nutrient, but when it comes to GLP-1, it’s one of the most powerful, largely because of how fiber reaches the gut. Instead of being broken down quickly, it feeds the beneficial gut bacteria, which then produce compounds that stimulate the release of GLP-1. Nutritionist and ARTAH founder Ryan Stephenson says this is one of the easiest wins for metabolic health, especially since most people simply don’t eat enough fiber. “In the UK, the average adult consumes around 18g of fiber a day, when the recommendation is closer to 30g,” he says. The answer is to actively build more fiber into your diet – beans, lentils, chia seeds, oats, raspberries, avocados, almonds and peas are all great choices.

If fiber feeds your gut bacteria, fermented foods help them grow—and this is where things get interesting. Scientists are increasingly discovering that the microbiome plays a strong role in regulating appetite, including how much GLP-1 your body produces. When beneficial bacteria break down fiber in the gut, they create compounds that signal the body to release hormones responsible for satiety—that’s where fermented foods come in. “A spoonful of sauerkraut with lunch, kefir at breakfast or a small portion of kimchi at dinner can help introduce more beneficial microbes into the gut,” says Ryan.

Interestingly, many of the foods that naturally support GLP-1 are the same ones found at the heart of the Mediterranean diet—a long-term way of eating that has been linked to better metabolic and cardiovascular health. Think extra virgin olive oil, dairy, leafy greens, herbs, nuts, beans and green tea. These foods are rich in plant compounds that help nourish beneficial gut bacteria, which in turn play a role in regulating appetite hormones. “Your gut microbes respond incredibly well to this type of food,” explains Jean-Marc. “When you regularly eat things like olive oil, berries, and other colorful plants, you’re essentially feeding the bacteria that help stimulate GLP-1.” Small changes go a long way—adding extra olive oil to your vegetables, adding dairy to your yogurt, snacking on nuts, or swapping your afternoon coffee for green tea. Over time, these foods help create a gut-like environment where satiety hormones can function properly.

It may be one of the simplest wellness tricks – but the science behind it is compelling. Research suggests that the order in which you eat your meals can significantly affect blood sugar and satiety hormones, including GLP-1. “The most effective order seems to be fiber and vegetables first, then protein and fat, with carbohydrates,” says Jean-Marc. Starting with fiber-rich foods slows digestion and creates a kind of natural buffer before the carbs arrive. Protein then creates feel-good hormones like GLP-1, helping the body prepare for the rest of the food. The result? A steady blood sugar response and a very gradual increase in GLP-1. “In real life, this means starting dinner with a salad, vegetable soup or roasted vegetables, before moving on to the rest of the meal. Research suggests that doing this can reduce postprandial glucose levels by up to 75%,” she says.

Another lifestyle habit that appears to support GLP-1 is time-restricted eating—essentially allowing a longer gap between dinner and breakfast. “Even a 12-14 hour overnight fasting window can help improve how responsive your body is to GLP-1 production,” says Jean-Marc. “It allows the hormone you’re already producing to work more efficiently,” he explains. Finishing dinner a little earlier or delaying breakfast a little can be enough to create a window—and many people naturally cut back on late-night eating as well.

Exercise isn’t just about burning calories—it’s increasingly recognized as a powerful tool for supporting metabolic health, including the hormones that regulate appetite. “Moderate to vigorous exercise is one of the most reliable ways to increase GLP-1 levels,” says Jean-Marc, adding that regular exercise can increase the hormone itself while making the body more responsive to it. The good news is that you don’t need punishing workouts to benefit. Even a 20-30 minute brisk walk after a meal can help lower blood sugar and support the satiety signal.

Ryan adds that exercise works on several appetite hormones at once. “High-intensity exercise, such as HIIT and endurance training, has been shown to significantly increase GLP-1 production,” he explains. “Exercise can also suppress ghrelin—the hormone that triggers hunger—while increasing PYY, another hormone associated with fullness.”

If you are sleep deprived, your appetite hormones are usually high. “Sleep plays an important role in appetite regulation,” Kim says, explaining that poor sleep can disrupt hormones that control hunger and satiety, including GLP-1. When you’re sleep-deprived, the body often craves quick energy — usually in the form of sugar or starchy foods — while the signals that tell you you’re full are less effective. Effects can also appear quickly. “Just getting less than six hours of sleep a night lowers GLP-1 levels and controls blood sugar the next day,” adds Jean-Marc.

Stress doesn’t just affect your mood—it can disrupt the hormones that regulate appetite, energy, and blood sugar. “Chronic stress and high cortisol can suppress GLP-1 production,” continues Jean-Marc. Over time, this can make the body less responsive to the signals that tell you you’re full after eating. High stress levels can also affect the gut microbiome and insulin sensitivity, creating the type of metabolic environment where low energy, cravings and late-afternoon lethargy become more common. The solution is to find ways to bring your nervous system back into balance on a regular basis – think daily walks, yoga, breathing exercises or time outdoors. These small moments of recovery help lower cortisol levels and support the hormonal systems involved in appetite and energy regulation. As Jean-Marc says, “When the nervous system is relaxed, the body’s metabolic signals—including GLP-1—work more efficiently.”
