The Paleo diet and the Keto diet are two very different things, yet they share certain similarities that often lead them to be compared or even confused. So, what is the difference between Paleo and Keto?
A Whole Food Approach To Eating
Paleo and Keto are popular dietary approaches that focus on eating whole, unprocessed foods, yet they differ in their primary principles and goals.
The Paleo diet revolves around mimicking the eating patterns of our ancestors, emphasizing natural foods like meat, fish, vegetables, fruits, nuts, and seeds while avoiding grains, legumes, dairy, and processed items.
The Keto diet aims to put the body into ketosis, a metabolic state where fat is burned for energy instead of carbohydrates. This is achieved by adopting a high-fat, moderate-protein, and very low-carbohydrate eating plan.
While both diets focus on healthier choices, their methods and food restrictions cater to different lifestyle and health goals.
Let’s explore the fundamentals of each diet in turn.
What Is the Paleo Diet?
The Paleo diet, often referred to as the “caveman diet,” is based on the idea of eating in a way that mirrors the dietary habits of our ancestors during the Paleolithic era. The central principle is to consume whole, nutrient-dense foods that were likely available to early humans before the advent of agriculture and modern food processing. This means the diet prioritizes foods like lean meats, fish, fresh fruits, vegetables, nuts, and seeds.
The Paleo philosophy centres around the belief that our bodies are better adapted to these natural, unprocessed foods than the grains, dairy, and highly refined products that dominate the modern diet. It aims to eliminate foods introduced during the agricultural revolution, such as legumes, grains, and added sugars, which are thought to contribute to various health issues today.
By focusing on eating real, whole foods and avoiding artificial additives, Paleo enthusiasts strive for improved digestion, reduced inflammation, better energy levels, and overall well-being—all inspired by ancestral eating habits.
What Is the Keto Diet?
The ketogenic diet, often referred to as “keto,” is a low-carb, high-fat diet designed to shift the body into a state called ketosis. Ketosis occurs when the body begins to burn fat for energy instead of carbohydrates, leading to the production of molecules known as ketones. This metabolic state can help improve energy levels, support weight management, and even positively impact certain health conditions.
The foundation of the keto diet lies in significantly reducing carbohydrate intake, typically to less than 50 grams per day, and increasing consumption of healthy fats like avocados, olive oil, nuts, seeds, and fatty fish. Protein is consumed in moderate amounts to meet bodily needs without disrupting ketosis. Foods like sugary snacks, grains, starchy vegetables, and most fruits are typically avoided due to their high carbohydrate content.
By focusing on fat as the primary energy source, the ketogenic diet aims to stabilize blood sugar levels, enhance mental clarity, and promote fat burning. Though initially challenging for some, this way of eating has gained popularity for its potential benefits in managing weight, promoting metabolic health, and supporting overall wellness.
Key Differences Between Paleo and Keto
The paleo diet is based on eating foods that mimic the diet of our hunter-gatherer ancestors, focusing on unprocessed meats, fish, eggs, vegetables, fruits, nuts, and seeds while avoiding dairy, grains, legumes, and processed foods. It prioritizes a clean and natural approach to eating without strict macronutrient requirements. The primary focus is on nutrient density and avoiding modern agricultural products believed to be harmful to health.
On the other hand, the ketogenic diet is centred around achieving and maintaining the state of ketosis by strictly limiting carbohydrates (usually less than 50 grams per day) and increasing fat intake. Unlike paleo, keto is less concerned with the types of foods consumed and more focused on the macronutrient ratios to ensure the body uses fats, rather than carbohydrates, as its main energy source.
Another notable distinction is their stance on dairy. Many keto followers include high-fat dairy products like cheese and butter in their meals, as these are excellent sources of fats and low in carbs. Paleo, however, typically excludes dairy altogether since it wasn’t a staple in ancestral diets.
Ultimately, while both diets have the potential to support healthy living, they cater to different preferences and objectives. Paleo is suited to those seeking a more natural and ancestral approach to eating, while keto is ideal for those aiming for metabolic changes through carb restriction and fat adaptation.
Carbohydrates and Grains on Paleo and Keto
A major crossover between Paleo and Keto in terms of foods and ingredients is the question of carbohydrates and more specifically, grains.
The Paleo diet can be considered grain-free, as grains are not on its list of allowed ingredients. Grains, such as wheat or barley, are not only considered to be a modern industrial food crop but are also thought to contain compounds that are supportive of optimal health.
The Keto diet, whilst not specifically grain-free, does encourage the elimination of grains as they are a major source of carbohydrates.
Oats, wheat and other cereal grains are pretty much off the menu for both diets, so alternatives such as nuts and seeds feature highly in both diets. This keto granola is a great breakfast cereal for both diets.

The Benefits of Paleo and Keto
When it comes to health benefits, both Paleo and Keto offer distinct advantages, depending on individual goals and lifestyles.
The Paleo diet emphasizes whole, unprocessed foods, which can lead to improved digestion and reduced inflammation. By eliminating processed grains, dairy, and artificial additives, Paleo can help individuals with sensitivities or allergies, such as lactose intolerance or gluten intolerance. Many followers also report increased energy levels and better blood sugar regulation due to the reliance on nutrient-dense fruits, vegetables, and protein sources.
On the other hand, the Keto diet is well-known for its ability to promote weight loss, particularly fat loss, by encouraging the body to use fat as its primary fuel source. This metabolic state, known as ketosis, not only supports fat burning but can also enhance mental clarity and focus. Additionally, Keto has been linked to potential therapeutic benefits, such as managing certain neurological conditions like epilepsy and even aiding in blood sugar control for individuals with type 2 diabetes.
Both diets encourage a break away from heavily processed foods and sugary snacks, setting the stage for a wholesome approach to eating. However, as with any diet, it’s crucial to consider personal health needs and consult with a healthcare professional when deciding which plan might be best for you.
Who Should Choose Each Diet?
When deciding between the Paleo and Keto diets, it’s important to consider your personal goals, lifestyle, and health conditions.
The Paleo diet might be a great fit if you’re looking to adopt a more natural approach to eating, emphasizing whole foods and avoiding processed ingredients. It’s particularly suitable for those who want to boost their overall health, improve digestion, or lower inflammation, as its focus on nutrient-dense foods supports these outcomes. If you’re an active individual or an athlete, Paleo’s inclusion of healthy carbs like sweet potatoes and fruits can provide the energy needed for performance and recovery.
On the other hand, the Keto diet could be the better choice for those aiming primarily for weight loss, especially fat loss, or individuals managing conditions like type 2 diabetes or epilepsy. If mental clarity and sustained focus are priorities, the ketogenic state may offer additional benefits in these areas. That said, Keto is often stricter in its requirements, demanding careful tracking to maintain ketosis, which may not be ideal for everyone. Those who enjoy structure and are willing to commit to a low-carb, high-fat ratio may find success with Keto.
Ultimately, both diets can be effective when tailored to your needs, and the decision should align with your health goals, preferences, and lifestyle. Consulting a nutritionist or doctor can help ensure the diet you choose is safe and sustainable for you.
Common challenges people face with Paleo and Keto
Adopting either the Paleo or Keto diet can come with its own set of challenges.
For those following the Paleo diet, one of the most common hurdles is the elimination of many modern convenience foods. Eliminating grains, dairy, and processed snacks, can make meal planning and dining out more complicated.
It can also be challenging to maintain a diverse and balanced diet if proper planning isn’t in place.
On the other hand, individuals on the Keto diet often find it difficult to manage the strict macronutrient ratios required to stay in ketosis. This means constantly monitoring carb intake, which can be overwhelming, especially for beginners.
Additionally, some experience the “Keto flu” in the early stages, which can include symptoms like fatigue, headache, and irritability as the body adjusts to burning fat for fuel instead of carbohydrates.
Both diets can be more expensive, as they require higher-quality ingredients.
These challenges highlight the importance of preparation, flexibility, and long-term sustainability when choosing either Paleo or Keto.
A Final Word
As we have seen, both the Paleo and Keto diets offer unique approaches to improving health and achieving personal wellness goals.
While both diets have their benefits they also come with challenges. Maintaining the strict guidelines of these diets can be daunting, and preparation is key. The cost of higher-quality ingredients, compared to a diet of cheap processed foods, is certainly a factor to be considered.
Ultimately, the choice between these diets—or any dietary approach—will depend on your personal health goals, preferences, and lifestyle. It’s always a good idea to consult with a healthcare professional or nutritionist first.
With proper planning, flexibility, and commitment, either diet has the potential to positively impact your health and well-being.
