Beef for the carnivore diet is not one-size-fits-all. Ribeye and eye of round are both beef, but their nutritional profiles are so different that choosing the wrong cuts can leave you hungry, under-fueled, or failing to hit the fat intake your body needs to thrive on a zero-carb diet.
This guide ranks the eight best beef cuts for the carnivore diet by fat ratio, nutrient density, and practical usability — with exact nutritional data so you know exactly what you are eating.
Why Fat Ratio Matters on the Carnivore Diet
Without carbohydrates, your body runs on fat. Most carnivore practitioners target 60 to 80 percent of calories from fat — the same metabolic state that makes the ketogenic diet work, except carnivore achieves it more completely.
The practical consequence: beef cuts that sound "healthy" in a conventional context can actively undermine a carnivore diet. Chicken breast, sirloin, and eye of round are too lean to sustain energy on their own. You will likely feel lethargic and hungry within days of starting if your default cuts are too protein-heavy.
A 2021 survey of 2,029 carnivore dieters published in Current Developments in Nutrition found that 84% of respondents prioritized red meat as their primary food source — and the most commonly cited staple was fatty beef.
The cuts below are ranked with this fat-energy balance in mind.
The 8 Best Beef Cuts for the Carnivore Diet
1. Ribeye Steak
Ribeye is the gold standard for carnivore eating. The heavy intramuscular marbling — that distinctive white webbing running through the meat — delivers a fat profile that no other common steak matches. At roughly 291 kcal, 24g protein, and 21g fat per 100g cooked, it provides more fat calories than protein calories in a single cut.
Beyond the macros, ribeye is packed with zinc, B12, selenium, and heme iron — the bioavailable form your body absorbs far more efficiently than plant-based iron.
2. Ground Beef (80/20)
Ground beef 80/20 is the practical backbone of most carnivore diets. It provides 254 kcal, 26g protein, and 17g fat per 100g cooked — a fat ratio that supports sustained energy throughout the day. It is affordable, cooks in minutes, and works for every meal from breakfast patties to dinner bowls.
For higher fat needs, the 73/27 blend pushes fat up to around 20g per 100g and is widely available at most grocery stores. Ground beef also makes it easy to cook organ meats in — mixing in 10 to 20% beef liver gives you the micronutrient density of organ meat without the strong flavor.
3. Short Ribs
Short ribs are the most calorie-dense cut on this list, delivering approximately 295 kcal, 19g protein, and 25g fat per 100g when braised. That unusually high fat-to-protein ratio makes them ideal for days when your energy needs are high or when you want to hit your fat targets without eating a large volume of food.
They are also one of the most forgiving cuts to cook — long, slow braising in a Dutch oven or slow cooker breaks down the connective tissue into gelatin, which supports gut health and joint function.
4. Chuck Roast
Chuck roast hits a sweet spot between fat content and cost. At roughly 225 kcal, 26g protein, and 13g fat per 100g cooked, it is leaner than ribeye but significantly fattier than chicken or sirloin. The cut becomes remarkably tender when slow-cooked, and the rendered fat bastes the meat throughout the cook.
Chuck is also one of the most budget-friendly options for carnivore dieters, making it a practical everyday cut for anyone who does not want to eat ribeye every day.
5. Brisket
Brisket consists of two muscles — the flat (leaner) and the point (fattier, also called the deckle). Together they average around 240 kcal, 26g protein, and 14g fat per 100g cooked, though the point end alone runs considerably higher.
Low-and-slow cooking transforms brisket from tough and fibrous to silky and rich. It is also one of the best cuts for bulk cooking — a full packer brisket (10 to 14 lbs) yields enough meat for several days of meals with minimal active cooking time.
6. T-Bone / Porterhouse
T-bone and porterhouse steaks are cut from the short loin and include both a New York strip (leaner) and a tenderloin filet (slightly leaner still) separated by the T-shaped bone. Combined, they deliver approximately 247 kcal, 27g protein, and 15g fat per 100g cooked.
The bone marrow in the T-bone is a quiet bonus — it contains healthy fats, fat-soluble vitamins, and collagen precursors. If you are the type to crack the bone and eat the marrow, you are adding a prized carnivore food with no extra shopping required.
7. New York Strip
NY strip is leaner than ribeye but still a solid choice, providing around 271 kcal, 26g protein, and 19g fat per 100g cooked. Its firm texture holds up well to high-heat cooking methods like reverse searing, and the fat cap on the edge can be trimmed (if you prefer leaner) or left on (recommended on carnivore).
8. Skirt Steak
Skirt steak is the leanest cut on this list at approximately 205 kcal, 27g protein, and 11g fat per 100g cooked. It has an intense beefy flavor from its high myoglobin content and cooks quickly over high heat.
On carnivore, skirt steak works best when cooked in or topped with added fat — butter, tallow, or marrow — to compensate for its lower fat content. It is a practical choice when your grocery budget is tight or when you want a high-protein, lower-calorie day.

ℹ️ Reading the Fat % Column
The carnivore diet typically targets 60–80% of calories from fat. Short ribs and ribeye hit that range automatically. For leaner cuts like chuck roast, skirt steak, or brisket flat, cook in butter or tallow to bring the fat percentage up without adding carbohydrates.

Organ Meats: The Micronutrient Upgrade
Muscle cuts provide protein and fat, but they leave significant micronutrient gaps on a carnivore diet. Organ meats close those gaps.
Beef liver is the most important addition. A 100g serving contains more than 16,000 IU of vitamin A, over 70 mcg of B12, 6.2 mg of iron, and meaningful amounts of copper and zinc. Adding 100 to 150g of liver two to three times per week fills most of the nutritional gaps that an all-muscle-meat diet creates.
Beef heart contributes CoQ10 — one of the few foods that genuinely concentrates this compound — along with B12, iron, and zinc. Its flavor and texture are closer to regular steak than liver, making it easier to incorporate for newcomers.

Budget vs. Premium: A Practical Buying Guide
You do not need to eat ribeye every day to succeed on the carnivore diet.
Cost-Effective Carnivore Beef Strategy
Buy chuck roast, ground beef 80/20, and brisket in bulk as your daily staples — these cuts provide excellent fat content at a fraction of the price of premium steaks. Reserve ribeye, short ribs, and NY strip for 2 to 3 meals per week when your budget allows. This approach covers your fat and protein targets daily without overspending.
A few practical tips:
- Buy in bulk — warehouse stores like Costco often sell ground beef and chuck roast at 30 to 40% below supermarket prices.
- Choose fatty ground beef — 73/27 is typically cheaper per pound than 80/20 and delivers more fat per gram.
- Explore less-popular cuts — beef cheeks, oxtail, and beef shanks are often inexpensive and extremely fatty once slow-cooked.
- Ask the butcher — cuts like beef suet (pure fat trimmed from the kidneys) are sometimes given away or sold cheaply and are pure fat with no protein, useful for boosting fat intake on lean days.

How to Use This in Your Meal Plan
The eight cuts above map naturally onto a weekly rotation. Use the fattier cuts (short ribs, ribeye, 73/27 ground beef) to anchor your fat intake, fill in daily meals with chuck and brisket, and save skirt steak and NY strip for high-protein lower-calorie days if you are managing a deficit.
For a structured approach, see our carnivore diet meal plan — it includes a full week of meals built around these cuts with daily calorie and macro targets.

Frequently Asked Questions
What is the best beef cut for the carnivore diet?
Ribeye is widely considered the best all-around cut because it delivers the highest fat-to-protein ratio among common steaks — roughly 21g of fat per 100g cooked — supporting the 60–80% fat calorie target that most carnivore practitioners aim for. Ground beef 80/20 is the most practical everyday choice for the same reason.
Is ground beef good for the carnivore diet?
Yes. Ground beef 80/20 is one of the most popular carnivore staples because it provides around 254 kcal, 26g protein, and 17g fat per 100g cooked. It is affordable, versatile, and easy to cook in bulk. The 73/27 blend delivers more fat if you need to increase your fat intake.
How much beef should you eat per day on carnivore?
Most carnivore practitioners eat 1 to 2 pounds (450–900g) of beef per day, eaten to satiety rather than a fixed calorie target. Tracking your intake for the first few weeks with Caloria helps you identify your natural baseline and adjust portions to match your carnivore diet weight loss or maintenance goals.
Can you eat leaner beef cuts on the carnivore diet?
Leaner cuts like skirt steak and sirloin are allowed, but they work best with added fat — butter, tallow, or bone marrow — to prevent under-fueling. On their own, very lean cuts can leave you hungry and low-energy because the carnivore diet relies on fat as its primary fuel source.
Is brisket good for the carnivore diet?
Yes. Brisket is an excellent carnivore choice. The point (deckle) end is significantly fattier than the flat and provides higher calorie density. Brisket is also one of the most budget-friendly options for carnivore dieters buying in bulk — a full packer brisket yields several days of meals.
