Keto VS Paleo Diet… What Are The Differences?

The Ketogenic and the Paleolithic diets are two very popular these days. Although they are based on very different principles, the two have many similarities. Can one replace the other, or maybe can one integrate the other? Here you are going to see the Keto VS Paleo Diet fight. Joking, it’s not a fight!

Keto Diet

The Ketogenic diet has become popular in recent years, but it is not so recent. Medical research showed already decades ago that the Keto Diet can mitigate some medical conditions.

The Keto Diet is a diet that promotes Ketosis. Ketosis is a metabolic state where your body burns fat in order to produce energy. In normal circumstances, the body prefers to burn glucose (sugars) first, and in case these are missing, then use fat. The Keto Diet forces the body to use fat through a change of macronutrients ratios. With the Ketogenic Diet, an individual has to cut the carbs intake and increase the fat intake, so the body uses the last as fuel.

The main principle of a Keto Diet is to start and stay in Ketosis, which is to use fat as fuel. To do this, the actual rule to follow is to follow the macro ratios of 70% fat, 25% proteins, and 5% carbs intake. The Ketogenic Diet does not limit what you can and cannot eat; it limits where your calories have to come from. As a consequence, however, the Keto Diet requires cutting most of the carbs food like pasta, rice, grains, bread, starchy vegetables, fruits, sweets, and anything rich in carbs.

The main reasons to follow a Keto Diet are:

  • Treatment of medical conditions
  • Fat Loss
  • A more stable level of energy

Paleo Diet

The Paleolithic is a period of time that spans from 3 million years ago until around 12.000 years ago. It is a period of time characterized by the development of stone tools by the humanity of the epoch. The Paleolithic Diet, or Paleo Diet, is based on the food consumed at that time. In the Paleolithic age, humans used to consume food as a result of hunting, fishing, scavenging. In addition, they could also find fruits and wild vegetables.

The main principle of the Paleo Diet is if a caveman could eat it, then you can eat it. On the opposite, if some food wasn’t available to a caveman living in the Paleolithic, then you cannot eat it. For example, the following are normally avoided by Paleo diet practitioners:

  • Dairy
  • Salt
  • Sugars
  • Bread and Pasta

In the Paleo Diet, you are not concerned about your macronutrient ratios. However, you have limitations in your food choice.

Why do people follow the Paleo Diet? It can be for one of the following:

  • Weight loss, reducing carbs intake
  • The belief that it is healthier

The assumption is that our body is more used to processing Paleo food because that is what was available for 3 million years, and “only” in the last 10.000 years have we introduced agriculture and processed food.

What Are The Differences Between Keto VS Paleo Diet

Keto VS Paleo Diet, who is the winner? Well, it is not a fight; there are differences between Keto Diet and Paleo Diet, but also similarities.


While the Keto Diet was “created” to treat medical conditions, the Paleo Diet is believed to be a healthy diet. Both diets have research highlighting their advantages and disadvantages. In recent years they can both be used as weight loss alternatives.


The Ketogenic Diet requires the following specific macros ratios with an intake of 70% fat, 25% proteins, and 5% carbs. There is no concern about macros percentages in the Paleo diet.


With the Paleo Diet, you can only eat something if it was available in the Paleolithic age, hence if you could get it with hunting, fishing, scavenging. In the Keto Diet, most food containing carbohydrates is to be kept to the minimum to stay in Ketosis.

As a result, the main differences in nutrition are:

  • Dairy not allowed in the Paleo but cheese is Keto Friendly
  • Fruits and Starchy Vegetables, very limited in Keto, allowed in the Paleo Diet
  • Grains, to be limited in the Keto, not available in the Paleo
  • Beans and Legumes, to be avoided in both diets


Keto vs. Paleo diet is not usually confused between each other. They have some differences but also many similarities in terms of purpose, principles, and food allowed. Under some circumstances, it is possible that a diet is both Keto and Paleo; however it requires extra attention to the food intake.
