Keto vs. Carnivore: What’s the Difference?

Both keto and carnivore are low-carb diets. Both can help you lose weight, cut sugar, and feel better.

But they are not the same.

Keto lets you eat veggies, nuts, and dairy. Carnivore doesn’t.

This guide breaks it down simply—no hype, no guessing.

🥑 What Is the Keto Diet?

Keto is a high-fat, low-carb diet. The goal is to get your body into ketosis, where it burns fat instead of carbs.

• Carbs: Usually under 20–50 grams per day
• Fat: Makes up 70–80% of calories
• Protein: Moderate

You can eat meat, cheese, eggs, oils, low-carb vegetables, and some nuts.

Keto has been studied for weight loss, blood sugar control, and even epilepsy ¹.

🥩 What Is the Carnivore Diet?

Carnivore is a zero-carb diet. You only eat animal-based foods.

• Carbs: Close to zero
• Fat: High
• Protein: High

It’s like keto, but stricter. No plants, no fiber, no carbs.

Typical foods:

• Beef, pork, chicken
• Fish and shellfish
• Eggs
• Animal fat
• Sometimes dairy (varies by person)

Some people also eat organ meats or bone broth. But no vegetables, nuts, fruits, or grains.

⚕️ What the Research Says

Keto has a solid evidence base. It’s been shown to help with:

• Weight loss
• Blood sugar control
• Type 2 diabetes
• Metabolic health
• Epilepsy (especially in children)
  Sources:
• Cleveland Clinic
• NIH/NLM
• Diet Doctor

Carnivore is newer and lacks long-term studies. Some early research and anecdotal reports suggest benefits like:

• Weight loss
• Less bloating
• Fewer autoimmune symptoms

But experts warn that cutting out all plant foods may limit key nutrients ⁴. More studies are needed.

✅ Why Some People Choose Carnivore

• Simplicity: No tracking, no cooking sides
• Autoimmune relief: Some report fewer flares
• Gut issues: Cutting fiber may reduce symptoms
• Extreme elimination diet: Used to identify food triggers

But it’s not for everyone. Carnivore is more restrictive and harder to stick with long-term.

---

❌ Carnivore Risks to Consider

• Nutrient gaps (like vitamin C or magnesium)
• Constipation from zero fiber
• Higher saturated fat intake
• Less variety in food = harder to sustain
• No long-term safety data

If you try carnivore, work with a doctor and consider blood tests to watch for deficiencies.

🧍 Who Might Prefer Keto?

Keto works well for people who:

• Want to lose weight without giving up veggies
• Like some flexibility in meals
• Don’t want to eat only meat
• Need more evidence before going full carnivore

You can even do clean keto—no processed stuff. Learn more: Dirty Keto vs Clean Keto

🧍 Who Might Prefer Carnivore?

Carnivore might appeal to you if:

• You feel worse after eating plants
• You want an extreme reset for gut or autoimmune issues
• You like meat and don’t need variety
• You’ve already tried keto and still have symptoms

Some people use carnivore as a short-term tool, not a forever diet.

🔎 Real Example

Jake, 37, went keto to lose weight and cut sugar cravings. It worked—but he still had bloating and eczema.

He tried carnivore for 30 days. His skin cleared up, and his digestion felt better.

Now? He eats mostly carnivore during the week and adds avocado or berries on weekends.
