I’m an Expert Nutritionist – These 4 Traditional Diets Work Like Ozempic

In 2025, over 15 million people in the U.S. alone are using GLP-1 medications like Ozempic and Wegovy to manage hunger and blood glucose levels. But long before these injectables, traditional diets around the world were naturally achieving similar metabolic benefits. Maria AbiHanna, nutrition expert at Food Label Maker, argues that ancestral diets may offer overlooked lessons in weight and glucose control:

“Many of the world’s oldest diets already do what GLP-1 drugs aim to replicate,” says AbiHanna. “They slow digestion, control hunger, and stabilize blood sugar, without side effects or prescriptions.”

Here are some of the most effective ancestral diets and why they work:

1. The Mediterranean diet mimics GLP-1 by creating fullness and glycemic stability.

Olive oil, legumes, whole grains, and vegetables are the main components of this region’s plates. These foods slow digestion and stimulate the gut’s release of GLP-1 and related peptides. Eating like a Mediterranean can reduce post-meal glucose spikes and snacking urges.

Recommendation: Add 1–2 tablespoons of extra virgin olive oil daily to salads or cooked vegetables. Replace refined grains with ½ cup of cooked lentils or bulgur, and aim for one plant-based meal rich in beans and greens at least three times per week.

2. The traditional Japanese diet activates GLP-1 through its high-fiber, low-glycemic composition.
From seaweed and miso to grilled fish and fermented pickles, this diet creates gut health and insulin sensitivity. Research links natto (fermented soybeans) to increased GLP-1 levels and improved glucose control.

Recommendation: Include 1–2 tablespoons of fermented foods like kimchi, miso, or pickled radish per day. Eat grilled or steamed fish at least twice a week, and experiment with adding a sheet of nori or ½ cup of seaweed salad as a side.

3. The Nordic diet relies on root vegetables, oily fish, and berries to enhance metabolic hormone response.

Like its Mediterranean cousin, this diet includes anti-inflammatory fats and slowly absorbed carbs. Wild blueberries and rye bread, in particular, slow gastric emptying, which is a key mechanism of GLP-1 action.

Recommendation: Start your morning with ½ cup of berries (fresh or frozen), switch to rye bread for sandwiches, and aim for two servings (about 3–4 oz each) of oily fish like salmon or mackerel weekly.

4. The Okinawan diet is protein-light but fiber-dense, supporting gut peptides and satiety.The Okinawan diet includes fiber-rich foods like purple sweet potatoes and bitter melon, which support gut health and stimulate the release of GLP-1-related hormones.

Recommendation: Roast or steam ½ to 1 cup of sweet potato for lunch or dinner. Add ¼ teaspoon of turmeric to soups or teas, and try stir-frying ½ cup of bitter greens or melon weekly as a side dish.

Closing

Modern science is catching up to what ancestral wisdom already knew: whole foods, thoughtfully combined, can reshape metabolism.

“These diets aren’t fads, they’re finely tuned metabolic systems passed down through generations,” says AbiHanna.

While drugs can trigger GLP-1 responses synthetically, she argues food is the original pharmacology. “For many people, returning to ancestral eating might be the most sustainable way to increase metabolic health.”
