You have probably heard about the increasingly popular Paleo diet recently. The roots of this special diet, as you might guess from its name, go back to the Paleolithic Age. If you are ready to discover more about the eating habits of our earliest ancestors, let’s get started!
Did you know that the Paleo diet, which seems like a new eating discipline, was first introduced in 1975? This diet emerged with the book “The Stone Age Diet” by American gastroenterologist Walter Lyle Voegtlin and takes its name from the Paleolithic Age, the period when the first traces of the human species appeared. In its simplest form, the Paleo diet is based on mimicking the eating habits of early humans. This diet is also known as the “Stone Age diet,” “hunter-gatherer diet,” and “caveman diet.”
There are not many details known about the Paleolithic Era. The lack of concrete information about the eating habits of early humans and the possibility that food consumption varied by region indicate that there are still unclear or unresolved aspects of the Paleo diet.

The Paleo diet is based on the idea of modeling the eating habits of people from the Paleolithic era in modern times. This diet includes foods that humans obtained through hunting and gathering, while excluding other foods from the daily diet. It is believed that the foods introduced into the daily diet following the advancements in agriculture and technology have negative effects on the functioning of the human body, which forms the main concept of the diet.
Some studies suggest that there have been evolutionary changes that allowed humans to adapt to different dietary patterns since the Paleolithic era. For example, a gene that evolved in regions where dairy farming began 6 to 8 thousand years ago helps digest the sugar in milk, known as lactose. However, this gene is not as common in regions where dairy farming was not widespread. This is a key point of contention against the main concept of the Paleo diet.
How to Follow the Paleo Diet?
What is the Paleo Diet
There are three main focus points that individuals starting the Paleo diet should pay attention to:
- Eat What Early Humans Ate: Everything that people from the hunting and gathering era ate, such as fruits, vegetables, fish, and seeds, is allowed. All other foods, especially processed ones, should be avoided.
- Drink Plenty of Water: Staying hydrated is crucial.
- Exercise Regularly: Regular physical activity is essential in the Paleo diet.
Those who adopt the Paleo diet believe that it is a way of eating that can prevent certain diseases. It is especially recommended to include fish and lean meat products in the daily diet. This is because they contain Omega-3 fatty acids, which, according to the American Heart Association, have the potential to reduce the risk of heart disease and stroke. Additionally, for harmful foods like sugar, which are prohibited in the Paleo diet, alternatives such as dates are offered.
What Foods Can Be Eaten on the Paleo Diet?
What is the Paleo Diet
On the Paleo diet, all foods that are believed to have been consumed during the hunter-gatherer era can be eaten. Priority is given to unprocessed foods, especially those without added salt and sugar. The foods that can be consumed on the Paleo diet are listed in order of importance as follows:
- Seafood: Rich in protein and Omega-3 fatty acids.
- Lean Meats: Low in saturated fats, high in protein, B12, zinc, and iron (especially meat from grass-fed animals).
- Eggs: Containing Omega-3, protein, vitamin A, and choline.
- Unprocessed Oils: Derived from fruits and seeds.
- Nuts and Seeds: Containing monounsaturated and polyunsaturated fatty acids, fiber, vitamins, minerals, and phytonutrients (excluding legumes like peanuts).
- Non-Starchy Vegetables: Low in calories and rich in vitamins, minerals, phytochemicals, and fibers.
- Sweet Potatoes: Specifically included in the diet for their high nutritional value.
- Fresh Fruits: Rich in antioxidants, phytochemicals, and fibers.
What Foods Should Be Avoided on the Paleo Diet?
What is the Paleo Diet
The transition of humans to settled life and the onset of modern agriculture introduced new and processed foods, in addition to those consumed during the Paleolithic era. For the past few thousand years, dairy products, legumes, and grains have taken a strong place among staple foods. This shift signifies that modern human diets have diverged from what hunter-gatherer ancestors consumed.
Advocates of the Paleo diet argue that the human body hasn’t evolved to process dairy, legumes, and grains effectively. They believe that consuming these foods can increase the risk of certain diseases such as heart disease, obesity, and diabetes. The foods to be avoided on the Paleo diet are listed as follows:
- All grain products like wheat and barley
- Legumes such as beans, lentils, and peanuts
- Dairy products like milk, cheese, and yogurt
- Starchy vegetables
- Processed foods like cakes, cookies, crackers, and chips
- Added sugar and salt
- Soda and sugary drinks
- Refined vegetable oils
What Are the Advantages of the Paleo Diet?
What is the Paleo Diet
- Potassium-rich diet: The Paleo diet emphasizes the consumption of fruits and vegetables, which are rich in potassium. Potassium is important for maintaining blood pressure, kidney function, and muscle function.
- Focus on unsaturated fats: The diet includes the consumption of unsaturated fats that contain essential nutrients for the human body, such as those found in nut oils, avocado oil, and olive oil.
- Meeting protein needs: The Paleo diet ensures the intake of proteins necessary for the growth and development of skin, muscles, bones, and cartilage.
- Minimal salt and sugar intake: Since the Paleo diet excludes processed foods, salt and sugar consumption is minimal. This can help balance blood sugar and blood pressure levels, reducing the risk of diabetes.
- Low-calorie diet: The diet involves consuming low-calorie foods, which can aid in weight loss.
A study conducted in 2019 revealed that individuals following the Paleolithic diet experienced not only weight loss but also reductions in waist circumference and body mass index (BMI). Since excess weight is a major risk factor for the development of chronic diseases, the researchers conducting the study believe that adhering to the diet could potentially reduce the risk of chronic diseases. However, these studies are still considered insufficient. Therefore, it is recommended to consult with a specialist before starting the Paleo diet.
What Are the Disadvantages of the Paleo Diet?

Insufficient Calcium Intake: Many people typically obtain adequate levels of calcium from dairy products such as milk, cheese, and yogurt. However, the Paleo diet does not allow for dairy products, which can lead to calcium deficiencies and potentially cause issues with bones and teeth for those following the diet.
Low Fiber Consumption: The exclusion of whole grains in the Paleo diet results in lower fiber intake, which is beneficial for gut health.
Limited Mineral Intake: The diet restricts the consumption of legumes, which are rich in essential minerals such as magnesium, selenium, and manganese that are important for gut health.
Uncertainty in Meals: The diet includes a wide variety of foods presumed to have been eaten during the Paleolithic era. However, there is insufficient evidence to determine the exact quantities and proportions of these foods consumed in ancient times.
Practical Difficulties: Since animals and plants have evolved over the past 10,000 years, it is not entirely feasible for modern humans to adopt the exact diet of their ancestors.

The Paleo diet is not recommended for individuals with certain health conditions, such as heart disease, kidney issues, diabetes, and pregnant women. Even those who appear to be in good health should consult a healthcare provider before starting the Paleo diet to ensure there are no underlying health concerns that could be affected by this dietary change.
Frequently Asked Questions About the Paleo Diet (Caveman Diet)
The Paleo diet continues to gain popularity with ongoing research shedding light on its benefits and intricacies. Naturally, this popularity leads to an increase in curiosity and questions about the diet. Here are some of the most frequently asked questions about the Paleo diet:
Is the Paleo Diet the Same as the Dukan Diet?
Although there are similarities, the Paleo diet and the Dukan diet differ in several key aspects. Here are the main differences:
- Both diets prefer animal protein consumption, but the Paleo diet emphasizes eating free-range and grass-fed animals, whereas the Dukan diet does not have such a requirement.
- The Paleo diet allows for the consumption of all pre-agricultural, unprocessed foods, while the Dukan diet restricts choices to a specific list of 100 foods.
- The Paleo diet prohibits the consumption of dairy products, whereas the Dukan diet permits dairy as a protein source.
- The Paleo diet allows for limited consumption of natural sugars like honey and maple syrup, while the Dukan diet strictly bans all natural sugars, allowing only artificial sweeteners.
How Long Can the Paleo Diet Be Followed?
There is no specific duration for the Paleo diet, and the length can be tailored to individual needs. It can be implemented in one-month cycles under medical supervision. Some studies have investigated the effects of following the Paleo diet for six, 12, 18, and 24 months. However, these studies have not yet provided sufficient data on the long-term effects of the diet. Additionally, following the diet long-term might be challenging due to the restriction of certain foods and nutrients.
Can Bread Be Consumed on the Paleo Diet?
No grain products are allowed on the Paleo diet. Consequently, bread, which is a grain product, is also prohibited.
Is Meat the Only Food That Can Be Consumed on the Paleo Diet?
While meat is a frequently consumed item on the Paleo diet, the diet is not limited to meat products. Eggs, natural oils, nuts, seeds, vegetables, and fruits are also included in the diet. However, it is crucial that all these products are unprocessed.
Are There Any Disadvantages to the Paleo Diet?
The Paleo diet excludes legumes like beans, peas, and lentils, as well as dairy products and grains such as barley, wheat, and rye. This exclusion can lead to deficiencies in magnesium, selenium, and manganese, as well as reduced intake of fiber and calcium in the long term. Insufficient consumption of these nutrients can cause issues in the intestines, teeth, and bones.
How Many Meals Should Be Eaten on the Paleo Diet?
The Paleo diet allows for three main meals a day: breakfast, lunch, and dinner. Additionally, natural snacks can be included as part of the diet.
