The focus of this week and next week is eating the most nutrient-dense food and dealing with adaptation symptoms.

All questions commonly asked by people new to the carnivore diet will be covered, for example, what to eat, how to cook your meat, how much should you eat, what to drink, and whether you need to supplement.

What should you eat

For the first week of your plan, all you are going to eat is fresh unprocessed ruminant meat and ruminant liver.

The reasons for this recommendation are set out below.

As mentioned in the overview post, the aim of this plan is to help people who are trying out the carnivore diet to fix their underlying health problems like compromised gut, diabetes, autoimmune conditions, and obesity-related health issues.

To support healing, you need the most nutrient-dense food and the best quality food possible. Ruminant meat and ruminant liver meet these criteria.

Our ancestors dined on large herbivores for millions of years and drove them to extinction.[1] The closest you can get to large herbivores these days are ruminants like bison, cows, elks, and buffaloes, not pigs, chickens, or ducks.

Furthermore, ruminants are also amongst the best raised farmed animals these days.

Farmed ruminants still spend most of their lives outdoor and eat a diet relatively close to their natural diets. They typically spend a large part of their lives grazing on pastures before finishing on grains.

Pigs and chickens, however, generally spend their entire lives in crowded sheds or cages and are fed a composite diet that is very different from their natural diets.

Therefore, the most ancestrally consistent and best quality food that you can eat is ruminant meat.

In addition to ruminant meat, liver is the true superhero of the carnivore diet.

Liver is loaded with so many essential nutrients. It is especially rich in vitamin A and B12 and high in riboflavin (B2), niacin (B3), pantothenic acid (B5), B6, folate. Liver is also a good source of copper, selenium, phosphorous, zinc and iron.

The best type of liver to get is ruminant liver (beef liver, lamb liver, etc.) but if it’s hard to source those, pork and chicken liver is okay.

As can be seen below, ruminant meat and liver can give you all nutrients that your body needs.

There is also a small amount of vitamin C in muscle meat but it is assumed to be zero by the USDA.

In short, you can get every nutrient your body needs from animal-based food. If you have any concerns about nutrition deficiency on the carnivore diet, please read this post “Is the Carnivore Diet Safe?”.

Although some nutrients in meat and liver may not meet their recommended daily intakes, don’t worry about it for now.

These recommended daily intakes are set for the general population who are on an omnivore diet with a high intake of plant food, hence plant anti-nutrients.

On the carnivore diet, with the absence of plant anti-nutrients, your body can absorb nutrients much better and your need is likely to be lower.

If you have never eaten liver before in your life, you can make it easier and break the first week of your plan into 2 weeks. Eat only ruminant meat for the first week and introduce liver in the second week.

Pasture-raised vs grain-fed

The general rule is to buy the best quality food you can afford.

If you can afford grass-fed meat, great. If you can’t, grain-finished is fine.

Beef cattle spend most of their lives grazing on pasture but spend the last 4 to 6 months in a feedlot where they are fed grains to accelerate weight gain.[2]

Grains are not as ideal as fresh grass but grains are just grass seeds after all and they are still consistent with ruminants’ overall diet.

Based on the USDA nutrition data, there is not much difference between the nutritional profiles of grass-fed and grain-fed beef. The main difference is a higher omega 3 content in grass-fed beef.

Joe and Charlene Anderson who have been on the carnivore diet for over 20 years say they just eat ordinary grass-raised grain-finished beef from the grocery store all these years.

While initially they ate grass-fed exclusively, they found that they felt much better on grass-raised, grain-finished meat because they reckon grains give the animals the nutrition that grass can’t.

Please buy only fresh unprocessed meat and liver, i.e. only buy single ingredient meat, no pre-marinated or seasoned meat to avoid additives.

Also, get the fattiest cuts of meat you can find in the shop. If you like ground meat, buy the budget one which will have a higher fat percentage and avoid the lean ground meat.

For now, don’t worry about counting macro or fat to protein ratio yet. Eat fatty cuts and you’ll be fine. We will look at tweaking to find the right fat to protein ratio for you later on.

How to cook your meat

There are people who say they feel best on raw meat but most people do just fine on cooked meat.

For now, just cook your meat to your liking but I would recommend having at least some of your meat lightly cooked (blue, rare, medium-rare, or medium) to retain some vitamin C.

As mentioned above, there is a small amount of vitamin C in muscle meat but there is a bit more in organ meat such as liver, brain and kidney.

You don’t need as much vitamin C on the carnivore diet compared to when you are an omnivore diet and you definitely can get sufficient vitamin C to avoid scurvy if you don’t cook through all your meat. If you are interested, please check out my post on the topic of vitamin C on the carnivore diet.

If you have limited kitchen skills, please check out this post for some tips on cooking the best steak.

If you are new to beef liver, please check out this post on how to cook liver and suggestions on various ways that you can enjoy liver on the carnivore diet.

If you have never eaten liver before, a lightly cooked piece of liver may be a hard ask. But this shouldn’t prevent you from eating liver. You can add 2 ounces of blended beef liver to 1 pound of ground beef to make meat patties. You won’t notice the taste of liver in the meat patties.

Another way is to add some diced liver to fatty meat chunks and stew for 3 hours or cook them in a slow cooker for about 6 hours.

When and how much should you eat

For the next few weeks, to keep things simple, don’t worry about the timing of your meal, listen to your body and eat when you are truly hungry and eat until you are full, but please don’t overeat.

However, try to eat the last meal of the day at least 3 hours before your bedtime so that your body can rest instead of digesting food.

As to liver, because it is especially high in vitamin A, there is some concern about vitamin A toxicity.

I have written a post on this topic where I provide a detailed calculation of how much liver you can safely consume in a day for various types of liver. Please check it out if you are interested.

In summary, you can eat 14 grams to 59 grams of beef liver a day or a couple of slices. This means no more than 0.9 pounds of liver per week.

You don’t need to eat a lot but it’s a good idea to make liver a regular feature of your meal.

Some people claim that they can eat a lot more liver than this but you don’t know how much your body can handle so stay on the safe side and you can experiment with it later.

What should you drink

I’ve written an in-depth post on the topic of drinks on the carnivore diet, please check it out.

In short, the best drink on the carnivore diet is water and please just drink to thirst.

Tea and coffee contain caffeine which is a stimulant that interferes with the normal healthy functioning of your brain.

The IMNCI center in Hungary has been using a high-fat animal-based diet (called the Paleolithic Ketogenic Diet) to treat many chronic conditions from 2011 with clinical experience from about 4000 patients. In their protocol, black and herbal tea are excluded but coffee is allowed only after full regeneration and in moderation.

If you choose to keep drinking tea, coffee, or herbal teas for now, I recommend drinking them two hours before or after your meal to reduce the impact of the anti-nutrients in these drinks on your body’s ability to absorb nutrients.

What about salt

Salt your meat as much as you like. There is no need to track how much salt you are consuming at this stage.

Sea salt is the best. Any brand will do.

Avoid table salt which has an anti-caking agent added.

You can do an experiment with and without salt later on in Week 6 of the program. But for now, just keep everything simple: salt as much or as little as you like.

What about seasonings

For the first couple of months, please don’t use any herbs, spices, or condiments.

While it might sound restrictive to you, as mentioned above, this series aims at people who are trying out the carnivore diet to fix their underlying health problems. As you don’t know what exactly might contribute to or cause your health issues, it’s best to stay with the safest and best food for now.

Later on in the program, you will have an opportunity to test out other animal-based food and spices and seasonings too to see what your body can tolerate.

And don’t worry, meat won’t be boring without seasonings.

If you only eat when you are genuinely hungry, meat tastes amazing by itself.

What about supplement

As mentioned in the last post, I don’t think you need to supplement, animal-based food can provide us with everything our body needs.

Supplementing will just prolong the adaptation process.

As mentioned in the last post, the IMNCI center in Hungry recommends taking no supplements. Only in rare cases, a one-off vitamin D supplement may be given. They have never experienced side effects or vitamin and mineral deficiencies in their patients who were on the Paleolithic Ketogenic Diet.

However, if you like, during the adaptation phase, you can take some electrolytes to help with lost electrolytes or lipase to help with fat digestion.

Sample meal plan

The simplest meal plan is seared steaks and a couple of slices of liver every day.

If you would like more variety, you can rotate between steaks, roast, meat patties, and meatloaf throughout the week. The meal plan below is an example.

Meal 1Meal 2
MONMeat patties Steak + 2 slices of seared beef liver
WEDRoastSteak + 2 slices of seared beef liver
THUSteakMeat patties
FRIMeatloaf Meat and liver stew
SATMeat and liver stewRoast +2 slices of seared beef liver

They may look plain and boring but, as mentioned above, if you only eat when you are really hungry, meat tastes super delicious by itself.

In addition, like many other people, you will find that on the carnivore diet, food is just a source of sustenance and no longer a form of entertainment. Your life will no longer revolve around food and it doesn’t control you anymore, leaving you with so much more mental bandwidth to pursue other things in life.

What you might experience this week

As you cut out carbohydrates in your diet, your body will be switching from burning sugar to burning fat for fuel.

As a result, you might experience a variety of short-term symptoms such as headache, brain fog, diarrhea, bad breath, muscle soreness, night sweat, fatigue, carb craving, and vertigo.

In addition, you are going to eat a lot of meat compared to before and your body will take time to ramp up the production of stomach acid and digestive enzymes to handle the sudden increase in fat and protein intake.

If you come from a ketogenic or paleo background, you might experience fewer and less severe symptoms.

If you come from a standard American diet with a high carb intake, you might experience more symptoms that may last for a longer period of time.

Regardless of the diet you’ve been on before or your health conditions, rest assured that all these side effects are only temporary. They will pass and you will feel better every day as time goes by.

Rest a lot, be patient and be gentle with your body, it is going through a lot to adapt to this new diet. You are providing it with the most nutrient-dense food to allow it to heal and rejuvenate. Trust its amazing ability and let it take its time.

Take-home message for this week

In summary, for the first week of your carnivore diet journey:

  • Eat ruminant meat (e.g. beef, lamb, bison, goat, kangaroo etc.) and ruminant liver
  • Eat only when you are hungry and eat until you are full but don’t overeat
  • Cook some of your meat to blue, rare, medium rare, or medium
  • Salt to taste
  • Drink water to thirst.

Don’t eat or drink anything that is not on the above list.

It is that simple.

If you feel like staying for longer on this week’s menu of only ruminant meat and liver for its simplicity, please do.

Next week, the focus is still on eating nutrient-dense food (in fact, this is what you will do on every single week of this plan) and dealing with adaptation issues. However, you will be introduced to more organ meat such as marrow, brain, and bone broth.
