The carnivore diet centers on animal-sourced foods: meat, fish, eggs, and select dairy. Everything from the plant kingdom is off the table, including fruits, vegetables, grains, legumes, nuts, and seeds. Within that framework, though, you have more variety than most people expect. Here’s a detailed breakdown of what qualifies.
Red Meat and Ruminant Animals
Beef is the cornerstone for most people eating this way. Steaks (ribeye, New York strip, porterhouse, T-bone, skirt), ground beef, brisket, and chuck roast are all staples. Fattier cuts are generally preferred because the diet relies on animal fat as its primary energy source, and leaner cuts alone can leave you under-fueled.
Lamb is equally welcome: lamb chops, lamb shanks, and ground lamb all fit. Beyond those two, you can include bison, venison, elk, and goat. Organ meats from any of these animals, including liver, heart, and kidney, are encouraged because they’re among the most nutrient-dense foods available. A 100-gram serving of beef liver, for instance, delivers 380 mg of potassium and 18 mg of magnesium, making it one of the best whole-food sources of minerals on this diet.
Poultry, Pork, and Eggs
Chicken, turkey, and duck are all permitted. Chicken thighs and wings tend to be more popular than breast meat because of their higher fat content. Pork, including pork chops, pork belly, and roasts, fits the diet as well.
Eggs are one of the most versatile foods you can eat on carnivore. They’re inexpensive, quick to prepare, and packed with fat-soluble vitamins. Most people eating this way consume several per day, cooked any style.
Seafood and Fish
All fish and shellfish are fair game. Salmon, sardines, mackerel, and other fatty fish provide omega-3 fats that are harder to get from land animals alone. Shrimp, crab, lobster, mussels, oysters, and scallops all count as animal foods. Canned fish like sardines and tuna work as convenient, budget-friendly options, though you’ll want to check labels for added vegetable oils or fillers.
Dairy: What’s In and What’s Out
Dairy is one of the more debated categories. The general rule is to stick with full-fat, low-lactose options. Aged hard cheeses like Parmesan, sharp cheddar, pecorino romano, Gruyere, and asiago are typically fine because the aging process breaks down most of the lactose. Heavy cream, butter, and ghee are also commonly included in small amounts.
Soft cheeses and higher-lactose products are usually avoided. That means milk, yogurt, ice cream, and fresh cheeses like Brie, mozzarella, burrata, cream cheese, and ricotta. To put the carb content in perspective, half a cup of 2% cottage cheese contains about 4.7 grams of carbohydrates, nearly all from lactose. If you’re eating strict carnivore, that adds up fast. Some people cut dairy entirely, especially during the first few weeks, to see how they feel without it.
Cooking Fats
Since the diet excludes plant oils, your cooking fats come from animals. Beef tallow is the most popular choice. It has a mild flavor and a high smoke point, making it ideal for searing steaks or frying eggs. Lard (rendered pork fat) is another versatile option that works well for frying or adding richness to leaner meats. Butter and ghee round out the list for those who tolerate dairy. Duck fat is also excellent for cooking at higher temperatures.
Many people save the drippings from cooking bacon or roasts and reuse them throughout the week. This is a practical way to keep your fat intake high without buying rendered fats separately.
Processed Meats: Read the Label
Bacon, sausage, jerky, and deli meats can work on carnivore, but the ingredient list matters. The things to watch for are added sugar, carb-based fillers, nitrates, and plant-derived spices. Many commercial sausages contain breadcrumbs, dextrose, or corn syrup. Bacon frequently has sugar or maple flavoring in the cure. Look for products where the ingredients are limited to meat, salt, water, and perhaps natural spices if you allow those.
Seasonings and Spices
This is where personal strictness comes into play. Purists eat meat with nothing but salt, or sometimes nothing at all. Most people, though, use salt freely and add black pepper in moderation. Salt is particularly important on this diet because your body excretes more sodium when carbohydrate intake drops to near zero.
A more relaxed approach opens the door to spices like turmeric, basil, bay leaf, sage, and thyme. These are technically plant-derived, so strict carnivore followers skip them, but many people find that small amounts of dried spices make the diet far more sustainable without meaningfully adding plant compounds. Where you draw that line is a personal choice.
Beverages
Water is the default drink. Plain sparkling water (unsweetened, no added flavors) is also widely accepted. Beyond that, opinions diverge.
Black coffee is the most common gray-area beverage. It’s zero calories and plant-derived, so strict zero-carb carnivore followers avoid it, but the majority of people eating this way drink it without issue. Unsweetened tea falls into the same category. Both are plant infusions, technically off-limits for purists, and practically harmless for most people’s goals.
What you should avoid is anything with artificial sweeteners. Aspartame and sucralose can spike insulin or disrupt gut hormones, which works against the metabolic reasons many people adopt this diet. That rules out diet soda, flavored waters with sweeteners, and most zero-calorie drink mixes. Bone broth, on the other hand, is fully carnivore-compliant and doubles as a source of electrolytes.
Electrolytes and Bone Broth
One thing that catches new carnivore dieters off guard is the need for extra electrolytes, especially in the first two weeks. When you drop carbohydrates, your kidneys flush sodium and water at a faster rate. Headaches, fatigue, and muscle cramps during the first week are almost always an electrolyte issue, not a problem with the diet itself.
During the adaptation phase (roughly weeks one and two), aim for 2,500 to 3,500 mg of sodium, 200 to 400 mg of potassium, and 60 to 120 mg of magnesium daily. After adaptation, those targets drop to about 1,500 to 2,500 mg sodium, 200 mg potassium, and 60 mg magnesium. Most carnivore dieters find they need ongoing sodium supplementation of 1,000 to 2,000 mg per day even after they’ve fully adjusted.
Homemade bone broth is a good complement: an 8-ounce cup provides roughly 200 to 400 mg of sodium (if salted), 50 to 100 mg of potassium, and 5 to 10 mg of magnesium. Organ meats also help. But bone broth and organ meats alone rarely cover the gap, so many people add salt to their water or make a simple electrolyte drink by mixing a teaspoon of Himalayan salt, half a teaspoon of potassium chloride, and half a teaspoon of magnesium citrate powder into two liters of water.
