Carnivore Diet Side Effects: Is It Healthy for You?

Are you also a meat lover and are worried that excessive meat eating can cause problems for you? Do you also want to know whether a carnivore diet is safe or not? We’ll clear up all your doubts.

Eating only carnivore diets is definitely not healthy at all because you are missing out on a lot of nutrients in this way. Yes, a carnivore diet can cause side effects if you are using it without eating vegetables, fruits, and other foods.

We will check out all the potential side effects of a carnivore diet in detail here. Stay with us till then, and you will know whether it’s safe or not.


The first and most common side effect of the carnivore diet is constipation. It occurs due to the lack of fiber in the diet because plant-based foods are the primary source of dietary fiber. Your bowel movements may be affected and difficult to pass due to a lack of fiber.

You should keep yourself hydrated if you are on a carnivore diet. Moreover, taking magnesium supplements or consuming foods rich in this mineral is also helpful for this purpose. These foods include fish, nuts, etc.

Heart Disease:

The second and potentially serious side effect is the risk of heart disease. It is because of its emphasis on high-fat animal products. Some of you may even notice improvements in cardiovascular risk factors like reduced triglyceride levels, but usually it causes problems like higher LDL cholesterol levels.

Eat leaner cuts of meat and take omega-3 fatty acids to stay safe. Moreover, monitor your blood lipid levels regularly under the guidance of a doctor.

Nutrient Deficiencies:

Eating only a carnivore diet may also cause nutrient deficiencies. It is because plant-based foods are rich sources of essential vitamins and minerals. You may notice common deficiencies in nutrients like vitamin C, fiber, potassium, and various phytonutrients. Taking organ meats, bone broth, and seafood can be helpful while dealing with it on a carnivore diet.


The fourth carnivore diet side effect on our list is high cholesterol levels. It is especially common in individuals predisposed to hypercholesterolemia. It is considered risky because it may lead to adverse cardiovascular effects. Monitor your cholesterol levels regularly and consult with a doctor to stay safe.


The next one is cramps. You may also notice cramps if you are eating only meat. It happens due to an electrolyte imbalance in your body. It is because animal products are low in potassium and magnesium compared to plant-based foods. Taking additional electrolyte drinks may help you deal with it.

Diarrhea on the Carnivore Diet:

The sixth potential carnivore diet side effect is diarrhea. Although constipation is more common, it may also occur in some cases. It happens due to changes in the gut microbiota and a sudden increase in fat intake. To avoid this problem, start by gradually increasing the carnivore diet. Eat smaller and more frequent meals to deal with it.


Nausea is another potential side effect of the carnivore diet. It is especially common during the initial transition phase. It happens due to changes in digestion and the body’s adaptation to a high-protein, high-fat diet.

Bad Breath:

Another carnivore diet potential side effect is bad breath. It is also called “keto breath.” It is a very common side effect of the carnivore diet. It happens due to the breakdown of fatty acids in the body. This results in the release of ketones through the breath. Its solutions include maintaining good oral hygiene, staying hydrated, and chewing sugar-free gum or mints.


Some of you may also notice more frequent headaches or migraines when switching to a carnivore diet. It is also called the “keto flu.” It may occur due to electrolyte imbalances, dehydration, or withdrawal from carbohydrates. Keep yourself hydrated, take more electrolytes, and gradually reduce your carbohydrate intake to effectively deal with it.

Irritability and Lack of Focus:

The last potential side effect we have is irritability and a lack of focus. It may occur due to changes in your blood sugar levels and neurotransmitter function. To maintain stable energy levels and cognitive function, it’s essential to eat a balanced diet. You must prioritize protein intake, stay hydrated, and incorporate healthy fats like avocado and olive oil into your diet.

Final Words

These were all the carnivore diet side effects. Eating this diet can only cause problems for you. It will affect each person differently. Even if it does not cause any side effects, it is still not a safe option.

You should always aim for a healthy and balanced diet. A balanced diet is an omnivore diet because it is a mix of both vegetables and meats. You get protein from the meat and other nutrients from the vegetables. Consult a doctor if you are having difficulty making the right diet plan for you.
