Keto vs Paleo — What's the Difference?
If you've spent any time in the health and wellness world, you've almost certainly come across both keto and paleo. On the surface, they look remarkably similar — both cut out processed food, both emphasise whole foods, both avoid grains and refined sugar. So what's actually the difference?
Quite a lot, as it turns out.
Keto and paleo are built on fundamentally different philosophies, produce different metabolic effects, have meaningfully different food rules, and suit different people for different reasons. Understanding the distinction makes it much easier to decide which approach — or which combination — is right for you.
In this guide we break down both diets clearly and honestly: where they overlap, where they diverge, what each one does in your body, and how to choose between them (or blend them) for your specific goals.
What Is the Paleo Diet?
The Paleo diet — short for Palaeolithic — is based on the premise that modern humans should eat the way our Stone Age ancestors did, before the advent of agriculture roughly 10,000 years ago. The philosophy is that our genes evolved over millions of years on a hunter-gatherer diet, and that the relatively recent introduction of grains, legumes, dairy and processed foods is the root cause of many modern chronic diseases.
The first modern advocate of the paleo diet was Dr Walter Voegtlin in the 1970s, but it was popularised significantly by Dr Loren Cordain whose 2002 book The Paleo Diet brought the concept to a mainstream audience. Since then, the paleo community has evolved considerably — with many variations and interpretations now in circulation.
What you eat on paleo
• Meat and poultry — grass-fed beef, free-range chicken, lamb, pork, game meats. Quality and sourcing are important in the paleo philosophy
• Fish and seafood — wild-caught is preferred; valued for omega-3 content
• Eggs — free-range preferred
• Vegetables — all vegetables are generally permitted, including starchy options like sweet potato, pumpkin and beetroot
• Fruit — all fruit is permitted, including higher-sugar fruits like bananas, mangoes and grapes
• Nuts and seeds — most are permitted, with some variations excluding peanuts (which are technically legumes)
• Healthy fats — avocado, olive oil, coconut oil, animal fats
What you avoid on paleo
• All grains — wheat, rice, oats, corn, barley, rye
• All legumes — beans, lentils, chickpeas, peanuts, soy
• All dairy — milk, cheese, butter, yoghurt, cream (a major point of difference from keto)
• Refined sugar and artificial sweeteners
• Processed foods — anything with artificial ingredients, preservatives or vegetable oils
• Refined vegetable oils — canola, soybean, sunflower, corn oil
• Salt — strict paleo limits added salt, though many modern paleo practitioners have relaxed this
The paleo philosophy in one sentence
Paleo is an ideology-first diet: it asks 'what would our ancestors have eaten?' and builds its food rules around the answer. Whether or not a food produces ketosis is not the point — food quality, ancestral appropriateness and avoiding the products of modern industrial food processing are what matter.
What Is the Keto Diet?
The ketogenic diet is a high-fat, very low-carbohydrate, moderate-protein dietary approach designed to shift the body's primary fuel source from glucose to ketones — fat-derived molecules produced by the liver when carbohydrate intake is sufficiently restricted.
Unlike paleo, keto has no interest in ancestral eating patterns or food ideology. It is a macronutrient-first approach: it asks 'what macronutrient ratio will keep my body in ketosis?' and builds its food rules entirely around the answer.
Keto was originally developed in the 1920s as a treatment for drug-resistant epilepsy — a therapeutic application that remains one of its most robustly documented uses. Its adoption as a weight management and metabolic health tool came much later and has accelerated dramatically over the past decade.
What you eat on keto
• High-fat foods — butter, ghee, cream, coconut oil, MCT oil, avocado, olive oil, nuts
• Full-fat dairy — cheese, cream, full-fat Greek yoghurt (a major difference from paleo)
• Eggs — one of the most keto-friendly foods available
• Meat, poultry and fish — all are fine; fatty cuts are particularly valued
• Low-carb vegetables — leafy greens, broccoli, cauliflower, zucchini, cucumber, asparagus
• Small amounts of low-sugar berries — strawberries, raspberries and blueberries in moderation
• Sugar-free sweeteners — stevia, monk fruit, erythritol (strict paleo avoids these)
What you avoid on keto
• All grains — same as paleo
• Most legumes — same as paleo
• Most fruits — higher-sugar fruits like bananas, mangoes, grapes and apples are avoided; berries in small amounts are okay
• Starchy vegetables — sweet potato, potato, pumpkin, corn, beetroot (these are permitted on paleo but restricted on keto)
• Sugar in any form — same as paleo
• Processed foods — same as paleo
The keto philosophy in one sentence
Keto is a metabolic state-first diet: it asks 'what do I need to eat to stay in ketosis?' and everything else follows from that. Whether a food is ancestrally appropriate is irrelevant — whether it keeps insulin low and ketones elevated is what matters.
Keto vs Paleo — The Key Differences
── PUBLISHER NOTE: Insert a formatted comparison table here for best SEO snippet potential ──
1. The fundamental philosophy
Paleo: 'Eat like our ancestors ate.' Food quality and ancestral appropriateness are the guiding principles. Ketosis is not the goal.
Keto: 'Keep carbs low enough to produce ketones.' Metabolic state is the guiding principle. Ancestral context is irrelevant.
This philosophical difference is important because it shapes everything else — which foods are allowed, how flexible the approach is, and how you think about exceptions and modifications.
2. Dairy — the biggest practical difference
This is the most immediately practical difference for most people.
Paleo: No dairy — milk, cheese, butter, cream, yoghurt and all other dairy products are excluded. The rationale is that dairy is a product of the agricultural revolution and wasn't part of the Palaeolithic diet.
Keto: Full-fat dairy is actively encouraged — cheese, butter, cream, full-fat Greek yoghurt are all keto staples and among the most convenient high-fat, low-carb foods available.
For many people, this single difference makes keto significantly more practical and enjoyable than strict paleo. For those with dairy sensitivities or who prefer to avoid it, paleo's dairy-free structure may be more suitable.
3. Carbohydrate approach — strict macros vs flexible whole foods
Paleo: Carbohydrates are not strictly limited. Starchy vegetables (sweet potato, pumpkin, beetroot), all fruit including high-sugar tropical varieties, and even some tubers are permitted — as long as they come from whole-food sources. A paleo diet can be moderate or even relatively high in carbohydrates, depending on how much fruit and starchy veg is consumed.
Keto: Carbohydrates are strictly limited — typically to 20-50g of net carbs per day. This means starchy vegetables and most fruit are off the table, regardless of how natural or whole-food their source. The carb ceiling exists to maintain ketosis, not because of ancestral arguments.
This is arguably the most significant metabolic difference between the two diets. Paleo does not reliably produce ketosis. Keto, by definition, does.
4. Sweeteners — natural is not the same as keto-friendly
Paleo: Natural sweeteners are generally avoided — including stevia, monk fruit and erythritol, which are seen as modern, processed products rather than ancestral foods. Some strict paleo practitioners also avoid honey (though others permit it in small amounts as an 'ancestral' sweetener).
Keto: Natural zero-carb sweeteners like stevia, monk fruit and erythritol are actively welcomed because they provide sweetness without raising blood sugar or disrupting ketosis. This makes the keto food landscape significantly more varied and enjoyable for people with a sweet tooth.
This is why you'll find an abundance of genuinely delicious sugar-free alternatives on keto — from the sugar-free chocolate range at Keto Direct to Funday Natural Sweets and Max Mallows Zero Sugar Marshmallows. Read our guide: Erythritol vs Monk Fruit vs Stevia — Which Sweetener Is Best?
5. Fat content — high fat on keto, moderate fat on paleo
Paleo: Fat is not specifically restricted, but paleo is not explicitly a high-fat diet. The focus is on food quality and whole-food sourcing rather than hitting a fat macronutrient target. A paleo meal might include lean meat, sweet potato and vegetables — a relatively balanced macronutrient profile that doesn't necessarily resemble the high-fat, moderate-protein keto structure.
Keto: Fat is the primary macronutrient — typically 60-75% of daily calories. This is a genuinely high-fat diet where the fat content is not just tolerated but actively required to fuel the body in the absence of carbohydrates.
6. Tracking and flexibility
Paleo: Generally more flexible. No macro tracking required. As long as you stick to paleo-approved foods, you eat to satiety without weighing or counting anything.
Keto: More precise, particularly in the beginning. Net carb tracking is important to ensure ketosis is maintained. Many beginners track macros closely for the first few weeks to develop nutritional literacy before transitioning to intuitive eating.
7. What the approach is based on
Paleo: Based on evolutionary biology and anthropology — the idea that our genetic makeup is better suited to the diet of our pre-agricultural ancestors.
Keto: Based on metabolic science — specifically the physiology of insulin, ketone production, and fat oxidation. Has the more robust clinical evidence base, particularly for weight loss, epilepsy management, metabolic syndrome and blood sugar control.
What Keto and Paleo Have in Common
Despite their differences, keto and paleo share meaningful common ground that explains why they're often grouped together:
• No grains — both eliminate wheat, rice, oats, corn and other grains
• No legumes — both avoid beans, lentils and chickpeas (for different reasons)
• No refined sugar — both strongly discourage added sugar in any form
• No processed foods — both emphasise whole, real food over industrially manufactured products
• No refined vegetable oils — both avoid canola, sunflower, soybean and similar industrial seed oils
• Emphasis on quality fat sources — both promote olive oil, avocado, coconut oil and animal fats
• Meat, eggs, fish and vegetables — the core of both diets
• Better blood sugar control — both diets reduce refined carbohydrate intake and may improve insulin sensitivity
• Whole-food philosophy — both prioritise real, minimally processed food over packaged and manufactured alternatives
This significant overlap is why people are often confused about the distinction. Both diets will dramatically improve the diet quality of most Australians eating a standard Western diet heavy in ultra-processed food, refined carbohydrates and added sugar.

Benefits Comparison — Keto vs Paleo
Keto benefits
• Reliable, measurable ketosis — the primary metabolic goal of the diet
• Powerful appetite suppression — ketones directly reduce hunger hormones
• Significant weight loss, particularly in the short-to-medium term
• Documented benefits for epilepsy, type 2 diabetes, metabolic syndrome, PCOS
• Rapid improvement in triglycerides and HDL cholesterol
• Strong mental clarity and cognitive performance once fat-adapted
• Better studied with more rigorous clinical evidence
Paleo benefits
• More nutritional flexibility — starchy vegetables and fruit provide a broader micronutrient range
• Easier to follow long-term for many people — no macro tracking, more food options
• Dairy-free by default — suitable for those with lactose intolerance or dairy sensitivity
• May be better for very active individuals or athletes who need more carbohydrate
• Strong emphasis on food quality and sourcing — grass-fed, free-range, wild-caught
• Generally considered easier to sustain socially — more flexibility when eating out
Which Is Right for You?
The honest answer is: it depends on your goals, your lifestyle, and what you're willing to track.
Choose keto if you:
• Have a specific metabolic goal — weight loss, blood sugar management, epilepsy control, PCOS
• Want to actively experience ketosis and its benefits (appetite suppression, mental clarity, fat burning)
• Are comfortable tracking net carbs, at least initially
• Don't have a problem with dairy — cheese, butter and cream are keto staples that make the diet very enjoyable
• Want access to a wide range of quality sugar-free alternatives that keep the diet interesting and sustainable
• Are looking for a diet with the strongest clinical evidence base for metabolic health outcomes
Choose paleo if you:
• Want a whole-food philosophy without macro tracking
• Have dairy sensitivity or prefer to avoid dairy entirely
• Are very active and need more carbohydrates for performance
• Value food quality and sourcing above metabolic state
• Find very low carb eating too restrictive for your lifestyle
• Are looking for a more flexible, intuitive approach to healthy eating
Consider a paleo-keto blend if you:
Interestingly, the two diets are not mutually exclusive — and combining them produces what some practitioners call a 'keto-paleo' or 'paleogenic' approach: the metabolic precision of keto applied to the whole-food quality philosophy of paleo. This means:
• Keeping net carbs under 50g (keto rule)
• Sourcing foods from whole, minimally processed origins (paleo rule)
• Avoiding dairy (paleo rule) or including quality full-fat dairy (keto rule — choose based on your preference)
• Avoiding grains, legumes, refined sugar and seed oils (both rules agree)
Many successful long-term keto practitioners naturally gravitate toward this combined approach — using keto's metabolic framework with paleo's emphasis on food quality. It produces a diet that is both effective and genuinely nourishing.

Frequently Asked Questions
Is keto the same as paleo?
No — though they share some similarities. Paleo focuses on ancestral eating patterns and whole-food quality; keto focuses on maintaining ketosis through strict carbohydrate restriction. The key practical differences are dairy (allowed on keto, not on paleo), starchy vegetables and fruit (allowed on paleo, restricted on keto), and sweeteners (allowed on keto, avoided on paleo).
Can you do keto and paleo at the same time?
Yes — and many people do. A combined 'keto-paleo' approach applies keto's strict carb limits alongside paleo's whole-food philosophy. The main decision point is dairy: keto encourages it, paleo avoids it. You can follow low-carb, whole-food keto without dairy if you prefer a more paleo-aligned approach.
Which is better for weight loss — keto or paleo?
Both can support weight loss. Keto has a stronger and more direct mechanism — by keeping insulin very low, the body is in an almost constant fat-burning state, and the appetite suppression from ketosis often reduces calorie intake spontaneously. Paleo supports weight loss primarily through removing ultra-processed foods and refined carbohydrates. For most people specifically targeting fat loss, keto produces faster and more measurable results in the short-to-medium term.
Is paleo lower carb than keto?
No — paleo is not necessarily low carb at all. Paleo permits all fruit (including high-sugar tropical fruits) and all starchy vegetables (sweet potato, pumpkin, beetroot, yams). A paleo diet could easily contain 150g or more of carbohydrates per day. Keto, by contrast, typically limits net carbs to 20-50g per day. Keto is significantly lower carb than paleo.
Do I need to track macros on paleo?
Not typically. Paleo does not require macro tracking — you simply eat from the permitted food list until satisfied. This is one of paleo's advantages over strict keto in terms of ease and flexibility. The trade-off is that without macro awareness, it's easier to consume more carbohydrates than might be optimal for metabolic goals.
Can I eat cheese on paleo?
No — dairy including cheese is excluded on strict paleo. If you love cheese, keto is significantly more accommodating. Full-fat hard cheeses are actually one of the most keto-friendly foods available — high in fat, moderate protein, virtually zero carbs.
Which diet is easier to follow long-term?
Most practitioners and researchers agree that paleo is generally more flexible and easier to maintain long-term for most people — particularly socially, when eating out, and for those who need more dietary variety. Keto requires more precision and commitment, but once fat-adapted, many people find the appetite suppression makes it easier to sustain than expected. Read more: Is Keto Safe Long Term?
Final Thoughts — Keto vs Paleo
Keto and paleo are both genuinely good dietary frameworks that represent a significant improvement over the standard Australian diet of ultra-processed food and refined carbohydrates. They're not rivals — they're different tools suited to different goals.
If you want the most powerful metabolic tool for fat loss, blood sugar management, appetite suppression and measurable ketosis — keto is the more precise and clinically supported choice.
If you want a whole-food eating philosophy that's more flexible, dairy-free, and suits a more active lifestyle — paleo offers real benefits without the strict carb counting.
And if you want the best of both worlds? Eat low-carb, whole-food, quality-sourced meals with the dairy option your body prefers — and stock your pantry with the products that make it genuinely enjoyable.
