The keto rash is a rare inflammatory skin condition that can occur as a side effect of following a ketogenic diet. It is characterised by itchy, red bumps that form a web-like pattern on the skin. The exact cause of the keto rash is unknown, but it is believed to be linked to ketosis, a metabolic state induced by the low-carb, high-fat nature of the keto diet. Other possible causes include a lack of fibre and plant-based foods, excessive fasting, and the production of inflammatory compounds. While the keto rash is uncommon, it is important to be aware of this potential side effect and seek appropriate treatment if it occurs.

What You'll Learn
Ketosis and inflammation
The ketogenic diet is a high-fat, low-carbohydrate diet that has been known to benefit epilepsy and other neurological illnesses. Ketosis is a metabolic state that the body enters when following a very low-carb diet or during starvation. The body begins breaking down fat into ketones and fatty acids, which it uses as an alternative source of fuel.
The keto diet can cause an inflammatory skin condition known as keto rash, or prurigo pigmentosa. This rash appears as raised, red, itchy bumps that take on a web-like appearance. It can appear anywhere on the body but is most common on the chest, back, and neck. The exact cause of the keto rash is unknown, but it is thought to be triggered by a drastic reduction in carb intake, excessive fasting, and the production of ketones, which may cause inflammation around blood vessels.
In addition to keto rash, there are other potential side effects of the ketogenic diet, including headache, nausea, fatigue, and constipation. These typically occur during the first three days of the ketosis induction phase and tend to disappear by the end of the induction phase.
Despite the potential side effects, the ketogenic diet has been found to have anti-inflammatory properties, particularly in the brain. Research by UC San Francisco scientists suggests that the diet may work by lowering inflammation in the brain, offering potential new therapies to reduce harmful brain inflammation following stroke and brain trauma. The ketogenic diet has also been found to improve insulin sensitivity, which contributes to its clinical effects.

Lack of fibre and plant-based foods
The keto diet is a low-carb, high-fat diet that is popular for weight loss. The diet focuses on protein and animal products, and followers eat fat at every meal. The diet typically requires followers to get up to 80% of their calories from fat and only 20 to 50 grams of carbohydrates per day.
The keto diet is often criticized for its lack of fibre. Dietitians frequently see patients who complain of constipation when they go on the keto diet. This is because the keto diet is low on fibre-rich foods.
The keto diet also tends to be low on plant-based foods. While followers of the keto diet may consume plant-based foods and oils, the diet's emphasis on animal proteins and fats means that plant-based foods are often lacking.
The lack of fibre and plant-based foods in the keto diet can alter gut bacteria, increasing the production of inflammatory compounds. This can contribute to the development of the keto rash, an inflammatory and uncomfortable skin condition that can appear in people who have started following the keto diet. The rash appears as raised, red, itchy bumps on the skin that take on a web-like appearance.
While the exact cause of the keto rash is unknown, it is thought to be linked to ketosis, a metabolic state that the body enters when following a very low-carb diet or during starvation. The keto diet's lack of fibre and plant-based foods may contribute to ketosis, which can trigger the keto rash.

High intake of red meat
The keto diet is a high-fat, low-carb diet that can lead to a metabolic state called ketosis, where the body burns fat instead of carbohydrates. While the keto diet is popular for weight loss, it can also have some negative side effects, including a rare skin condition known as keto rash. This rash is characterised by itchy, raised, red bumps that resemble a web-like pattern and predominantly appear on the chest, back, neck, shoulders, and abdomen.
Although the exact cause of keto rash is not yet fully understood, it is believed to be triggered by certain factors, including a high intake of red meat. Red meat is a common feature of the keto diet, and an increase in its consumption can alter gut bacteria, leading to higher production of inflammatory compounds. This alteration in gut bacteria may be a contributing factor to the development of keto rash.
The link between red meat consumption and keto rash is further supported by the understanding of Alpha-Gal Syndrome (AGS), also known as red meat allergy. AGS is an allergic reaction to alpha-gal, a sugar found in the tissues of all mammals except humans and other primates. When individuals with AGS consume red meat, they experience allergic reactions, including rashes, nausea, vomiting, and diarrhoea. While AGS is typically triggered by a tick bite, the high intake of red meat on the keto diet may exacerbate allergic responses in susceptible individuals.
It is important to note that the correlation between red meat intake and keto rash requires further investigation, as there are other potential triggers for the rash. These triggers include the state of ketosis itself, drastic reductions in carbohydrate intake, excessive fasting, and the production of ketones, which can cause inflammation around blood vessels. Additionally, nutrient deficiencies, especially in vitamins A, B-12, and C, have been linked to skin conditions and may play a role in the development of keto rash.
To summarise, while a high intake of red meat is one of the potential triggers for keto rash, it is not the sole cause. The development of the rash is likely influenced by a combination of factors, including dietary changes, nutrient deficiencies, and individual variations in metabolism and gut bacteria.

Nutritional deficiencies
The keto rash is a potential side effect of following the ketogenic diet or being in ketosis due to other factors. It is a rare, inflammatory skin condition that causes a red, itchy rash with bumps that can look like a web. The rash may resemble contact dermatitis or an allergic reaction. However, keto rash can be distinguished by the brownish discolouration of the skin that remains after the inflammation subsides.
The exact cause of the keto rash is unknown, but there are thought to be several associated conditions. Ketosis occurs most commonly as a result of restrictive dieting and can also be seen in diabetics. If ketosis is accompanied by uncontrolled sugars, it can lead to a life-threatening condition known as ketoacidosis.
Excluding entire food groups from your diet can result in nutrient deficiency and prurigo pigmentosa. Consuming a low-carbohydrate diet like the keto diet increases the risk of nutritional deficiencies due to a lack of nutrients from vegetables, fruits, whole grains, and legumes. As a result, low-carb diets are often insufficient in several nutrients.
To avoid nutritional deficiencies, you should supplement your diet with nutrients (minerals, vitamins, etc.). The level of minerals such as sodium, potassium, magnesium, and calcium can decrease soon after starting your keto diet. As they are vital for energy and cell function, you need to add these supplements to your diet. Vitamins such as Omega-3, vitamin D, and vitamin A are great for regulating inflammation.

Bacterial overgrowth
The keto rash is an inflammatory, uncomfortable skin condition that can appear in people who have started following a ketogenic diet. It is characterised by itchy, inflamed bumps or swelling with fluid inside. These tend to become scaly or crust over. As the condition progresses, these lesions will connect and form a symmetrical pattern.
The exact cause of the keto rash is unknown. However, it is associated with ketosis, a metabolic state that happens when the body switches from using carbohydrates as its main fuel source to fat. When the body enters ketosis, it produces ketones that may cause inflammation around blood vessels, resulting in skin rashes.
One theory to explain the keto rash is that the diet's lack of fibre and plant-based foods alters gut bacteria, leading to bacterial overgrowth. This is supported by the treatment for keto rash, which is antibiotic therapy. Doxycycline is the antibiotic most often used to treat keto rash as it reduces bacteria and helps decrease inflammation.
The keto rash is a rare condition and does not happen to everyone on the keto diet. It can appear anywhere on the body but is more common on the chest, back, neck, and abdomen. The rash may resemble contact dermatitis or an allergic reaction. However, it can be distinguished by the brownish discolouration of the skin that remains after the inflammation subsides.
If you believe that a recent change to your diet has caused a rash, you may want to consider reintroducing carbohydrates. Eating an array of colourful fruits and vegetables is a great way to ensure that you are getting all the vitamins and minerals your body needs.
