Mediterranean diet 101:
a complete guide
and meal plan
So, what is the Mediterranean diet? Is this a flavorful way of eating healthy?
A Mediterranean diet can provide health benefits, according to researchers. And eating a low-carb Mediterranean diet may provide even more benefits when it comes to losing weight and controlling diabetes.
In this guide, you’ll learn first about how to do a low-carb Mediterranean diet. We’ll also show you how you can add carbs back for a more typical Mediterranean diet, at a carb level that works best for you.
Plus, you’ll get tips about what to eat, along with meal plan examples for low-carb and higher carb Mediterranean diets.
Key takeaways
What do you eat on a low-carb Mediterranean diet? If you want to lose weight or improve your blood sugar levels, consider eating a low-carb version that eliminates grains, potatoes, rice, fruit, and other higher-carb foods without sacrificing the delicious, unique flavors of Mediterranean cuisine. Learn moreWhat do you eat on a standard Mediterranean diet? It’s easy to follow. Simply load up on colorful produce, whole grains, and other plants; include a protein source at each meal; add generous amounts of olive oil to your food; and enjoy red wine in moderation, if desired.

What are the potential health benefits of eating a Mediterranean diet? A Mediterranean diet is rich in fresh, minimally processed foods. Research suggests that eating this way may possibly help people improve their health. Learn more
1. What is the Mediterranean diet?
The Mediterranean diet is based on the traditional cuisine of people who live in the countries bordering the Mediterranean Sea, especially Italy, Greece, and Spain.
Though Mediterranean diets vary from country to country, they share common features. For instance, they all emphasize fresh, local, minimally processed foods.
While there isn’t just one type of Mediterranean diet, most include large amounts of fresh seafood, vegetables, fruits, whole grains, legumes, and olive oil.1
You can easily modify a typical Mediterranean diet to make it low carb.
2. The Mediterranean diet pyramids
On a Mediterranean diet, you can enjoy a wide variety of fresh and tasty foods. Here are two food pyramids: on the right is a low-carb Mediterranean diet; on the left is a typical Mediterranean diet.2
You can see that the big difference between the two is that the low-carb version does not have the bread, grains, and starchy vegetables. It also only has low-sugar fruit like berries.
In both cases, the pyramid is designed to help guide food choices with no set-in-stone rules for how much to eat. Instead, you decide how much to eat based on your hunger, weight goals, and preferences.3
3. What to eat on a low-carb Mediterranean diet
A low-carb Mediterranean diet combines two popular eating patterns: carb reduction and the fresh foods found in the Mediterranean region.
Strong evidence shows that low-carb diets can help people lose weight and control blood sugar.4
When eating a low-carb Mediterranean diet, you simply avoid the higher-carb foods such as bread, rice, potatoes, beets, and high-sugar fruit. (You can enjoy some of these occasionally in small quantities — and we’ll talk about how to add them back in later in this guide.)
The good news is that on the low-carb Mediterranean diet, you still enjoy generous servings of delicious proteins, vegetables, and olive oil at every meal.
Foods to eat
Eat at most meals:
-
- Protein: Seafood, poultry, eggs, cheese, or yogurt (include fish or shellfish at least twice a week)
- Above-ground vegetables, especially leafy greens, tomatoes, bell peppers, cucumbers, squash, greens, artichokes, eggplant, and broccoli
- Olive oil, olives, nuts, or seeds
- Herbs and spices
- Berries: one serving per day
Serving sizes
A half-cup serving of fruits or vegetables is about the size of a tennis ballEat in smaller amounts:
- Red meat (twice per week)
- Processed or cured meat, such as ham or prosciutto (once per week)
- Below-ground vegetables like carrots or onions (up to one-half cup a few times a week)
- Legumes (up to one-half cup a few times a week)
- Lemons, limes: in small amounts for cooking or to flavor beverages
Foods to avoid:
- Whole grains found in foods, such as: bread, pasta, cereal, quinoa, and couscous, etc.
- Potatoes
- Sugar, honey, syrup
- Foods with added sugar (candy, cookies, cakes, ice cream, and other sweets)
- Foods made with white flour (bread, pasta, cereal)
- Sweetened beverages
- Fruit juice
- Fruits: bananas, grapes, and most other fruit besides berries
What to drink
Drink still or sparkling water, with a squeeze of lemon or lime. You can also enjoy coffee or tea with a splash of milk or cream.
Many people include red wine at meals as part of their Mediterranean lifestyle. If you want to drink alcohol on a low-carb Mediterranean diet, choose dry rather than sweet red wine.
Studies suggest wine may reduce some heart disease risk factors. 5
If you are drinking wine, aim for a daily maximum of two glasses of wine if you’re a man or one glass if you’re a woman.6
Mediterranean low-carb recipes
Tips for dining out
Eating a low-carb Mediterranean diet in restaurants is a breeze:
- Choose grilled or baked, unbreaded seafood or meat with vegetables or a side salad.
- Request that your food be cooked with olive oil, and ask for olive oil to dress your salad.
- Request a double portion of vegetables to replace potatoes, rice, or other starchy sides.
- Order water or dry red wine to drink.
5. What to eat on a standard Mediterranean diet
If you have little or no weight to lose and do not have type 2 diabetes, you can include more carbs at your Mediterranean meals. This means you can eat some potatoes, brown rice, unrefined grains, or whole wheat bread. You can find the level of carbs that is right for you.
Adding carbohydrates will make your meals more typical of the standard Mediterranean diet. It will still be full of fresh, minimally processed food that is much healthier than the standard, highly-processed American diet.
If you find that when you eat more carbs you crave more carbs, that may be a sign that you have exceeded your personal carb threshold and should cut back.
Eat at most meals:
- Protein: Legumes (beans, chickpeas, lentils), seafood, poultry, eggs, cheese, or yogurt; include fish or shellfish at least twice a week
- Vegetables: All types, especially tomatoes, bell peppers, cucumbers, squash, greens, artichokes, eggplant, and broccoli
- Whole grains and starchy vegetables, such as whole-grain pasta or cereal, brown or wild rice, quinoa, couscous, and potatoes, etc.
- Fruits: All types
- Olive oil, olives, nuts, or seeds
- Herbs and spices
Eat less frequently:
- Red meat (twice per week)
- Processed meat, such as ham or prosciutto (once per week)
Foods to avoid:
- Fruit juice
- Foods with added sugar (candy, cookies, cakes, ice cream, and other sweets)
- Foods made with white flour (white bread, white pasta, white rice)
- Sweetened beverages
What to drink
Water is always a great beverage choice, whether still or sparkling. Coffee and tea with milk or cream are also fine.
Again, good news for wine lovers. Red wine at meals is typical of many Mediterranean diets, and studies suggest it may reduce some heart disease risk factors, as noted above. 7 However, it’s completely optional.
If you do consume alcohol as part of a Mediterranean diet, limit yourself daily to two glasses of wine if you’re a man or one glass if you’re a woman.8

Fortunately, it’s easy to eat a typical Mediterranean style meal at many restaurants. Here are some tips for dining out:
- Choose unbreaded, grilled or baked seafood, poultry, meat, or legumes with vegetables and a salad.
- Request that your food be cooked with olive oil, if possible.
- Ask for olive oil at the table to dress your salad.
- Ask for extra vegetables or salad to replace fries, or request whole grain pasta or bread rather than refined white flour versions.
- Order still or sparkling water, or enjoy a glass of red wine.
7. The history of the Mediterranean diet
The roots of the traditional Mediterranean diet date back to the ancient Greeks and Romans, whose mainstays were bread, olive oil, and wine. They also ate many other foods, such as seasonal fruits and vegetables, legumes, cheese, fish, and meat.10
Over time, different cultures influenced what would come to be known as the traditional Mediterranean diet. Spices from the Orient and Middle East, tomatoes from America, and contributions from other lands helped shape the unique flavors and classic dishes associated with the Mediterranean diet.11
Throughout the years, Mediterranean residents tended to eat what was available to them, as many continue to do today.
In addition to plant foods, most people who follow a traditional Mediterranean diet eat some meat, along with cheese (including sheep and goat cheese) daily or several times a week. Many also consume fish and shellfish frequently, depending how far they live from the sea.12
Although their diets are similar overall, people eat different foods depending on the Mediterranean country they live in:
- Italian diets feature tomatoes, basil, garlic, cheese (mozzarella, Romano, and ricotta, among others), fish, meat, pasta, and cured meats like prosciutto and pancetta.
- Greek cuisine is rich in olives, shellfish, feta, chickpeas, onions, bread, figs, and lamb.
- Spanish diets typically include fresh shellfish, roasted meat, legumes, peppers, rice, and cured meats like ham and chorizo.
8. The Mediterranean diet research
However, this type of evidence is considered very weak. Observational studies can only show associations between diets and health outcomes. They can’t prove that eating a certain way improves health or prevents disease.
Instead, it’s better to rely on results from clinical trials, especially randomized controlled trials, to assess a Mediterranean diet’s potential health benefits.
Is a Mediterranean diet effective
for weight loss?
If you want to lose weight, a Mediterranean diet may be a good option — but a low-carb Mediterranean diet is likely even better.
In a review comparing different clinical trials in adults with type 2 diabetes, people who followed a Mediterranean diet for 12 months lost an average of 13.5 pounds (6.2 kilos).14 Other studies suggest that Mediterranean diets can help people lose weight and reduce their waist size.15
One review of five Mediterranean diet trials found this dietary pattern was more effective than low-fat diets for weight loss but not more effective than low-carb diets for weight loss.16 And results from a separate trial suggest that a low-carb Mediterranean diet can help people lose more weight than a classic Mediterranean diet.
In that trial, 259 overweight people with diabetes followed a low-carb Mediterranean diet or a classic Mediterranean diet for one year. At the end of the study, people in the low-carb group lost 22 pounds (10.1 kilos), while those in the other group lost 16 pounds (7.3 kilos).17
In smaller trials, a ketogenic Mediterranean diet has shown impressive weight loss results.18 Although the evidence from these studies is considered weaker than randomized trials that have a control group, strong research shows that keto diets can help people lose weight.19
What does a ketogenic Mediterranean diet look like? In trials, people consumed meat, seafood, eggs, olive oil, cheese, above-ground vegetables, and in some cases red wine.
Is a Mediterranean diet beneficial
for heart health?
The Mediterranean diet is often described as a “heart-healthy” diet. Does it live up to this reputation? Perhaps, although some of its benefits may have been overstated.
Several trials have shown that eating a Mediterranean diet may reduce some heart disease risk factors.20
The PREDIMED trial followed more than 7,000 participants at high risk of heart disease for nearly five years. Those who were assigned to eat a Mediterranean diet (supplemented with either nuts or olive oil) had slightly better outcomes than those who followed a low-fat diet.21 22
A two-year trial in overweight people with heart disease found that losing weight on a Mediterranean diet can potentially help reduce the amount of plaque on artery walls.23
According to the authors of a 2019 study, the high intake of olive oil and nuts in Mediterranean diets seems to play a large role in reducing LDL and very low-density lipoprotein (VLDL) particles that may contribute to heart disease risk.24 However, despite encouraging results overall, a recent review of 30 trials concluded that it is unclear whether eating a Mediterranean diet helps prevent heart disease.25
Bottom line: Although the Mediterranean diet has been shown to help reduce some heart disease risk factors, more results from long-term trials are needed to reach definitive conclusions about its effects on heart health.
Does the Mediterranean diet provide other health benefits?
Following a Mediterranean diet may also improve some health conditions:
- Diabetes and prediabetes: In 2015, researchers who conducted a review of Mediterranean diet trials in people with type 2 diabetes found that they are more effective for lowering blood sugar levels than low-fat diets.26
A low-carb or keto Mediterranean diet may be even better than a classic Mediterranean diet for lowering blood sugar.27 When people with type 2 diabetes eat very low-carb diets, their blood sugar often decreases to the point that they are able to reduce or discontinue their diabetes medication.28
- Fatty liver: Results from some trials suggest that a Mediterranean diet may reduce liver fat in people with nonalcoholic fatty liver disease (NAFLD) or those at high risk for the disease.29 Low-carb and keto Mediterranean diets have been shown to dramatically reduce liver fat.30
Take home message
Mediterranean diets include a wide variety of fresh, flavorful foods such as seafood, meat, cheese, vegetables, olive oil, nuts, and berries. If you want to lose weight or control your blood sugar, you’ll likely get the best results by following a low-carb Mediterranean diet based on these foods.
Feel free to add whole grains, other starches, and higher-sugar fruits if you tolerate more carbs. However, these foods are entirely optional.
Both a low-carb and standard Mediterranean diet have been linked to potential health benefits. So if you’d like to try this way of eating, choose the one that best fits your health goals and food preferences.
