The Paleo Diet vs. Primal Diet: Who Is Each Diet For?

The Paleo and the Primal diets are based on our ancestors’ eating habits but their attitudes toward carbohydrates and the foods allowed bring significant changes in their results and effects. Comparing the Paleo Diet vs. Primal Diet helps us understand which one can be better for us.

What Is a Paleo Diet?

To compare the Paleo Diet vs. Primal Diet, we first need to learn about the specifics of each one.

Paleo, Paleolithic, or Caveman Diet is based on the eating habits of our ancestors in the Paleolithic era, who consumed whole, unprocessed foods, including lean meats, seafood, vegetables, fruits, nuts, and seeds.

This diet avoids foods such as dairy, grains, and processed foods that were not available in the Paleolithic era.

The Paleo diet follows this eating habit because it’s believed that it can prevent chronic diseases like heart disease, diabetes, and obesity and positively impact health.

The Benefits of the Paleo Diet

  • Blood Sugar Control: Whole, unprocessed foods and low glycemic index carbohydrates do not cause blood sugar spikes and insulin sensitivity [1].
  • Increased Nutrient Intake: Consuming whole foods can provide the necessary nutrients for bodily functions [2] [3] [4].
  • Reduced Inflammation: Anti-inflammatory whole foods allowed on the Paleo Diet can decrease inflammation [5] [6].

Despite these health benefits, the Paleo Diet may include some drawbacks.

The Drawbacks of the Paleo Diet

  • Nutrient Deficiencies: Those on a Paleo Diet may face deficiencies in vitamins like D and calcium if not properly balanced [7] [8].
  • Digestive Problems: Foods high in fiber, such as fruits and vegetables, can lead to digestive issues like bloating or gas [9].
  • Risk of Heart Disease: Some versions of the Paleo Diet may be high in cholesterol, which can negatively impact blood lipid levels and cause heart problems.

To avoid the possible side effects and use the benefits the Paleo Diet offers, we need to know what exactly we can consume. Learning about the foods allowed can also help us better compare the Paleo Diet vs. Primal Diet.

Paleo Diet Food List

Generally, you can consume the following foods on a Paleo Diet:

  • Meat and Poultry: beef, chicken, lamb, pork, turkey, etc.
  • Fish and Seafood
  • Eggs
  • Vegetables (excluding legumes)
  • Fruits
  • Nuts and Seeds
  • Vegetable Oils (e.g. avocado, coconut oil, olive oil)

Now that we know the basics of the Paleo, let’s learn about the Primal lifestyle, so we can compare the Paleo Diet vs. Primal Diet.

What Is the Primal Diet?

The Primal Diet is an elimination, animal-based eating plan, consisting of three main levels, including Low-Carb, Keto, and Carnivore Diets.

This diet focuses on balancing macronutrients and addressing the main causes of chronic illnesses (like diabetes, insulin resistance, cancer, and immune conditions), which is consuming the wrong foods.

The Primal Diet Food List

The foods you can consume on the Primal Diet depend on the level you are at. On the Low-Carb level, you can eat:

  • Meat
  • Fish and Seafood
  • Eggs
  • Butter and ghee
  • Vegetable Oils
  • Nuts and Seeds
  • Full-Fat Dairy
  • Leafy Greens
  • Cruciferous Vegetables
  • Berries, Avocados, Olives
  • Bone Broth
  • Herbs and Spices

On the Keto level, you can consume:

  • Meat
  • Fish
  • Seafood
  • Poultry
  • Healthy Animal Fats and Vegetable Oils
  • Eggs
  • Low-Carb Vegetables
  • Dairy
  • Nuts and Seeds

Learn all about the Keto Diet.

On the Carnivore Diet, you cannot consume any plant-based foods, only animal-based products, including:

  • Meat
  • Fish and Seafood
  • Poultry
  • Eggs
  • High-fat Dairy

Learn all about the Carnivore Diet.

Consuming these low-carbohydrate, high-fat, and moderate-protein foods can lead to various health benefits.

The Benefits of the Primal Diet

  • Improving Metabolism: Low-carb, ketogenic diets can improve metabolism by helping type 2 diabetes, improving blood glucose control, and lowering body weight [10] [11]. 
  • Managing Diabetes: The diet can decrease HbA1c and the need for antihyperglycemic medications in those with insulin resistance and type 2 diabetes [12] [13].
  • Reducing Inflammation: Inflammation is the source of various chronic conditions but low-carb, ketogenic diets like Primal can improve the subclinical inflammatory state in patients with type 2 diabetes [14].
  • Improving HDL Cholesterol Levels: Dietary fats in the Primal Diet can increase HDL (good) cholesterol levels, improving metabolic health and lowering heart problems.
  • Enhanced Mental Disorders: Studies show positive effects of ketogenic diets on psychiatric diseases [15].
  • Improved Digestion: Low-carbohydrate diets like Primal can promote weight loss and metabolic functions [16].

The Drawbacks of the Primal Diet

The Primal Diet does not include specific side effects, but there might be challenges, especially for beginners.

The main challenge is balancing macronutrients, lowering the consumption of carbohydrates, and dealing with temporary symptoms of keto flu, including headaches, diarrhea, constipation, nausea, etc.

Now that we know the basics about each diet, let’s compare the Paleo Diet vs. Primal Diet, and see which one suits which groups of people.

The Paleo Diet vs. Primal Diet

Although Paleo and Primal diets share similar principles as both follow the eating habits of our ancestors, they have differences in the foods they allow.

The main difference between the two diets is their carbohydrate intake. While Paleo allows low glycemic index carbohydrates, the Primal Diet focuses on minimizing carbohydrates gradually through the three levels it has.

Both diets focus on whole, unprocessed foods, especially meat. Although the Paleo Diet allows vegetables and plant-based foods, the Primal Diet allows them only in the first two levels.

Although meat is important in both diets, Paleo focuses on moderation. However, the Primal Diet focuses on meat as the main protein source of the third level.

Proper hydration is important in both diets. While water is the main drink in both diets, high-carb drinks, especially alcohol, are not recommended.

While low-carb fruits are only allowed in the first two levels of the Primal Diet, the Paleo Diet allows a wider range of fruits.

So, according to these differences, each diet can be more suitable for a specific group of individuals.

Who Is Each Diet for?

It’s no secret that there is no diet that works for everybody because each individual’s health status, nutritional needs, weight, body composition, and goals determine the best diet.

However, the Primal Diet can work for a large group of individuals because it contains three major levels by focusing on a gradual reduction of carbohydrates, which minimizes side effects.

Since your body has enough time to get used to the new low-carb lifestyle and the diet includes a wide range of foods, almost everyone can start from a level of the Primal Diet, based on their needs.

The Keto and Carnivore levels of the Primal Diet can lead to significant health effects for those dealing with chronic conditions like inflammatory diseases, autoimmune conditions, high blood sugar levels, insulin sensitivity, and even cancer.

Conclusion

Comparing the Paleo Diet vs. Primal Diet, we can say that the Primal can help a wider range of individuals because it contains three levels, which are designed based on carbohydrate intake.

However, please consult a healthcare provider before making big changes to your eating habits to ensure the new diet aligns with your health status, needs, and goals.
