The carnivore diet, an increasingly popular eating regimen centered around animal products, has garnered attention for its potential health benefits. However, some individuals following this diet have reported experiencing an uncomfortable side effect: itchy skin. While the carnivore diet itself isn't directly linked to a specific rash like the "keto rash," understanding the potential causes of skin irritation in the context of this diet is essential. This article explores the possible connections between the carnivore diet and itchy skin, drawing parallels with the well-known "keto rash" associated with ketogenic diets and offering potential solutions.
Keto Rash: A Potential Parallel
The ketogenic diet, characterized by extremely low carbohydrate intake and high protein and fat consumption, can induce a metabolic state called ketosis. In ketosis, the body shifts from using carbohydrates as its primary fuel source to burning fat, producing ketone bodies. While ketosis offers a range of potential health benefits, including promoting weight loss, it can also trigger a skin condition known as "keto rash" or prurigo pigmentosa.
Keto rash is a rare form of dermatitis, or skin inflammation. It is an itchy and uncomfortable rash that develops on the upper body. The keto rash is distinctive as it forms network-like patterns across the skin. It usually affects the upper body. Researchers do not yet know exactly why a ketogenic diet causes skin inflammation, but they believe that this rash may have a link with ketosis. Several different treatments and lifestyle measures can provide symptom relief.
Although the carnivore diet is not exactly the same as the keto diet, there are certain similarities. The carnivore diet is also extremely low in carbohydrate but high in protein and fat. When a person follows this eating pattern for enough time, their body starts to break down body fat for fuel instead of carbohydrates. The body converts fats into ketone bodies. A person has reached a state of ketosis when the body switches its primary energy source to these ketone bodies. It is possible that the state of ketosis achieved on a carnivore diet may cause the same rash as seen on the keto diet.
Potential Causes and Triggers
The exact cause of keto rash remains unclear, but research suggests that being in a state of ketosis could be a possible cause of the condition. In addition to the keto diet, fasting and diabetes can lead to a state of ketosis.

Other possible causes or triggers of a keto rash include:
- Hormonal changes that can occur during pregnancy and menstruation
- A complication of bariatric surgery
- Skin friction
If the itchy skin experienced on a carnivore diet is indeed related to ketosis, the factors above may also contribute to the problem.
Identifying the Rash
The keto rash appears as raised, red, itchy papules on the skin. Skin redness, or erythema, can be more difficult to detect on dark skin. The rash is more common on the upper body and tends to affect the:
- Chest
- Back
- Neck
Keto rash can resemble other skin conditions, such as confluent and reticulated papillomatosis, contact dermatitis, and some drug reactions. However, it is possible to distinguish keto rash by the network-like pattern that remains on the skin as the red bumps start to resolve. Over time, the inflammation will continue to reduce, leaving a brownish discoloring of the skin.
Treatment Options
There are several possible treatment options for someone with keto rash. For keto rashes that occur due to ketosis, eating more carbohydrate will usually resolve the rash, as this moves the body out of ketosis. In people with diabetes, administering insulin can reduce keto rashes. Research suggests that antibiotics, such as minocycline or tetracycline, can also treat the symptoms of keto rash. Friction between fitted clothing and the skin can trigger the keto rash, so wearing loose fitting clothing may also reduce it.

To relieve symptoms, it is also helpful to follow general treatment advice for good skin care, such as:
- Avoiding touching the rash where possible
- Keeping the fingernails short
- Moisturizing the area several times a day
- Avoiding contact with irritants, such as wool or strong detergents
- Avoiding hot or humid climates
- Washing the skin gently and avoiding excessive rubbing
Addressing Itchy Skin on the Carnivore Diet
If you experience itchy skin while following a carnivore diet, consider the following strategies:
- Assess Ketosis Levels: Determine if you are in a state of ketosis. If so, consider whether a less strict version of the diet with slightly more carbohydrates might alleviate the issue.
- Rule Out Other Causes: Consult a dermatologist to rule out other potential causes of the rash, such as allergies, eczema, or infections.
- Optimize Skin Care: Implement a gentle skincare routine, including moisturizing regularly with hypoallergenic products and avoiding harsh soaps or irritants.
- Consider Histamine Intolerance: The carnivore diet often involves consuming aged or processed meats, which can be high in histamine. Some individuals are sensitive to histamine and may experience skin issues as a result. Experiment with fresh, non-aged animal products to see if this makes a difference.
- Ensure Adequate Hydration: Dehydration can exacerbate skin problems. Drink plenty of water throughout the day to keep your skin hydrated.
- Address Nutrient Deficiencies: While the carnivore diet is nutrient-dense, it may lack certain micronutrients found in plant-based foods. Consider supplementing with vitamins and minerals as needed, under the guidance of a healthcare professional.
- Monitor Gut Health: Emerging research suggests a link between gut health and skin conditions. Consider incorporating fermented foods or probiotics to support a healthy gut microbiome.
- Manage Stress: Stress can trigger or worsen skin problems. Practice stress-reducing techniques such as meditation, yoga, or spending time in nature.
- Experiment with Elimination and Reintroduction: If you suspect a specific food within the carnivore diet is causing the rash, try eliminating it for a period and then reintroducing it to see if the rash returns.
- Consult a Healthcare Professional: If the itchy skin persists or worsens, seek guidance from a doctor or dermatologist. They can provide a proper diagnosis and recommend appropriate treatment options.
