Are you interested in Dr Shawn Baker’s carnivore diet?

Did you listen to Mikhaila Petersons’ story on how much better she feels mentally & physically on a carnivore diet?

In this beginners guide on the carnivore diet you will find out what the diet is, and how to easily get started.

What is the Carnivore Diet?

The carnivore diet is a dietary plan that involves eating just animal meat for all your nutritional needs.

On a strict carnivore dietary plan there are no plant based foods, like fruit or vegetables, or any processed carbohydrate foods like, cereals and grains.

The all meat diet is also known as the meat only diet, zero carb diet, beef only diet, or the carnivore diet, and is classified as a high protein diet.

How to Start The Carnivore Diet

1. Do a 30 Day Meat Only Challenge

30 Day Challenge to Start

For most people who want to try start eating a diet of only meat; starting with a 1 month challenge is a good way to start.

For 30 days you will follow the recommended protocols rules and tips.

Use this time to see if you subjectively feel better (better energy levels, less aches and pain, better sleep , less hunger etc…), or you can see better objective health changes (weight loss, better blood results like HbA1c numbers for diabetes, thyroid levels etc…).

Taking before and after pictures, keeping a health diary or tracking these lab results will then help you know if this is the diet plan for you, or not.

Don’t worry, it is very easy to get started. This way of eating is not complicated, but just needs a little preparation.

2. Eat Only Meat

Variety of Animal protein to eat


The carnivore diet is based on eating only animal meats. This means you should only eat 100% meat and organs when on the diet.

You will not be eating plant based protein like, soy or pea protein.

The recommended types of meat you can eat will be any type of animal based protein. Some people will add in minimal dairy fat and protein products like some cream or cheese, but some choose not to.

Eat the fatty cuts of meat & not only lean cuts of meat.

Natural saturated and unsaturated animal fat on the meat provides additional daily nutritional needs that your body requires to stay healthy; along with the protein, minerals, vitamins & other nutrients you get from meat. Plus, adding fat makes any food more tasty (palatable).

3. Drink Mainly Water

Staying adequately hydrated

Choosing to drink only water depends how strict you want to be on your carnivorous way of eating.

Most people are recommended to try drink water only for the first 30 days. This can be regular tap water, mineral water, spring water or filtered water.

A tips is to try add some Redmond Real salt to your water for extra electrolytes. The salt fix book author Dr James DiNicolantonio recommends you do to avoid issues.

A full, or strict, follower will eat just meat and only drink water. Whereas, others may include drinks like, coffee and tea, or other sources of fat like dairy products.

Some long-term carnivore diet followers, like Amber O’Hearn, find they still wish to drink coffee or tea. Do this as long as you are not adding sugar or sweeteners into your hot drinks.

Avoid any hot or cold beverages with added carbs like: soda drinks, vegetable drinks, energy drinks, protein powder shakes etc…

4. Eat Until Full

Eat enough protein


You will want to eat till you feel full (satiated).

Your appetite will change during the course of the the first month. Do not go hungry; eat to your energy needs.

Dr Baker mentioned on the Joe Rogan #1050 podcast interview how he has seen many people eat on average about 2 lbs (900 grams) of meat per day. However, since Dr Baker workouts out heavily, he likes to eat about 4 lbs (1.8kg) of meat per day.

5. Eat 1-3 Meals a Day

Time restricted eating window

You can eat three meals a day or practice intermittent fasting (IF) with one meal a day (OMAD).

How often you eat depends on your daily schedule and if you want to try add in more health benefits like practising timed fasting.

If you follow circadian biology thinking then protein in the morning within the first hour of waking helps to set your body clock; so a carnivore breakfast would be an important meal.

If you follow the advice from protein researcher Prof Stuart Phillips then eating protein throughout the day, plus in the evening, is a good idea to help maintain lean muscle mass.

6. Eat Cooked or Raw Meat

Degrees doneness when cooking steak

On the carnivore diet you can cook your meat how you like it.

Some people also choose to eat only raw meat.

High-end steak restaurants that value good tasting food cook red meat, like beef, to be medium rare and not well done. If you are not a fan of steak that is still pink or slightly bloody; you might find your tastes will change over time when eating meat everyday. You’ll likely come to start enjoying eating medium rare steak vs well done steak.

Cook other meats (chicken, bacon, fish) to make sure they are safe to eat.

I would not eat raw chicken, or raw bacon from a food safety point of view. However, raw seafood is a must try like, sushi sashimi salmon, tuna or fresh oysters.

Before and After Results on the Carnivore Diet

My Personal 30 Day Carnivore Diet Experiment Before & After Results.

Gary's before and after diet photos comparison

Nothing like doing something yourself to try learn and understand what effect it will have on your body. I love protein and eating meat, so to try this way of eating (WOE) was a a good dietary challenge I was willing to give a go.

The summary of the pictures shows how I lost about 10 lbs (4.5kg) in weight and my hip and waist measurements came down too. My goal wasn’t to lose weight, but I did end up shedding some excess pounds.

Doing the experiment I discovered a whole bunch of things like:

  • How much it costs to eat this way per day?
  • What kind of meat do I find easy and enjoy eating regularly?
  • What would this WOE did to my blood glucose and ketone levels?

Plus more.

I documented my thoughts each day in my Youtube daily vlogs about the my carnivore diet experience here and shared my blood ketone levels and glucose measurements on the Biohackers Lab instagram, like this picture below. (Tip: Use the Keto Mojo meter).

Good to know for those looking to do keto-carnivore.

Carnivore Diet Support Groups and Forums

If you need online support from others following this way of eating (WOE) then I would recommend the following resources:

Carnivore Diet FAQ’s

Q: Do I Only Need to Eat Grass Fed Meat?

No, grass fed meat has health and ecology benefits, but it does tend to cost more. There is no problem eating meat that doesn’t cost much and fits within your monthly budget available. Do not let choosing or trying to find only grass fed/finished meats stop you from starting.

Q: Can I Eat Processed Meats?

Yes, you can eat processed cold meats like ham, salami, chorizo, & pepperoni. However they are best avoided in the first 30 days if possible. This is because you may be ingesting extra carbohydrate fillers unknowingly with these types of deli meats.

Q: What Snacks Are Carnivore Friendly?

Carnivore friendly meat snacks include Epic meat bars, plain beef jerky or South African biltong.

Q: Are Sausages & Bacon Ok to Eat?

Yes, bacon is great to eat how much you want. However, some sausages contain added ingredients like wheat to help fill them out. So watch out for eating only cheap hotdogs & pork sausages.

Q: Is This a Long-Term or Short-Term Diet?

It can be used for needed short-term health changes like weight loss or long-term general health benefits. You will find people like Kelly Hogan in the zero carb diet community forums on Facebook and Reddit who have been eating a meat only diet for several years or decades with no negative health effects reported by them. A good example of someone who has been eating an all-meat diet since 1998 is Joe Andersen and his wife. You can make only eating carnivore diet a new way of life for you if you feel & see the benefits in your body.

Q: What About the Risk of Constipation?

The most common question is the worry about becoming constipated. You’ll find you will likely have regular bowel movements with less stools (faeces) per day. This is said because the meat is more easily broken down and absorb in the intestines and so there is less output vs a diet high in insoluble fibre. This stool chart is a good guide about consistency, which can change depending on many factors.

Q: Will Eating Too Much Meat Cause Kidney Damage?

No, eating more meat does not cause kidney or liver damage. There is good research that disproves the myth that eating the recommended daily allowance of protein or even more causes kidney function. In fact, the opposite can happen and kidney function might improve by removing excess glucose from your diet and improving insulin sensitivity.

Q: Do I Need To Take Supplements?

No, you should not need to take supplements on a carnivore diet. However, some people may find a benefit from taking some electrolyte support like a magnesium or potassium supplement.

Q: Will I Get Enough Vitamin C?

Yes, eating a diet of meat and organ meats will give you enough vitamin c and avoid scurvy.

Long-term carnivore, Amber O’ Hearn, explains this is not the case and why not. Strict carnivore eaters feel if you are eating the right types of meat, and enough of them, this should provide all your required vitamin and mineral needs.
