Keto Diet: Friend Or Foe To Eczema?

Eczema is a chronic inflammatory skin condition that affects an estimated 1 in 10 people during their lifetime. While there is no cure, many people are looking for answers beyond topicals. One approach that has gained traction in recent years is the use of a ketogenic diet to manage eczema. The ketogenic diet is a low-carb, high-fat, moderate-protein diet that has been shown to decrease inflammation in the body. While there is limited scientific evidence directly linking the keto diet to improved eczema symptoms, an abundance of success stories and some research suggest that it may be a viable option for those seeking alternative treatments.

The anti-inflammatory effects of keto

The ketogenic diet is a high-fat, low-carbohydrate regimen that has been used to treat epilepsy and other neurological illnesses. The diet changes the way the body uses energy, shifting it from glucose to ketones and keto acids as fuel. While the benefits of the diet in humans are less well-established, there is some evidence that it may help with inflammatory skin conditions like eczema.

Reducing Inflammation

The ketogenic diet has been shown to decrease inflammation, which is a key driver of eczema. This anti-inflammatory effect is linked to the production of ketones and keto acids, which have been found to suppress inflammatory genes and proteins. In particular, the ketone body beta-hydroxybutyrate (BHB) has been identified as having inhibitory effects on certain inflammatory proteins.

Reducing Sugar Intake

Sugar and refined carbohydrates can increase inflammation in the body. The ketogenic diet eliminates these inflammatory food groups, which may help to reduce skin inflammation.

Improving the Gut Microbiome

The gut microbiome plays a crucial role in skin health. An imbalanced gut microbiome can lead to an overgrowth of opportunistic bacteria and a decrease in beneficial bacteria, which can contribute to skin issues. The ketogenic diet can help bring the gut microbiome back into balance by reducing sugar intake, as most opportunistic bacteria feed off sugar.

Increasing Intake of Healthy Fats and Omega-3s

The ketogenic diet includes omega-3 fats found in foods like fatty fish, grass-fed beef, walnuts, flax seeds, and chia seeds. Omega-3 fatty acids have been found to improve eczema symptoms due to their anti-inflammatory effects.

Ensuring Optimal Nutrition

Malnutrition and nutrient deficiencies can impair skin health and wound healing. The ketogenic diet emphasizes optimal nutrition, ensuring sufficient intake of vitamins, minerals, and healthy fats, which are essential for maintaining skin health.

While more research is needed to fully understand the impact of the ketogenic diet on eczema, the anti-inflammatory effects of the diet may provide some benefits for individuals suffering from this inflammatory skin condition.

The impact of keto on the gut microbiome

The gut microbiome refers to the trillions of bacteria, fungi, and viruses living in the gut. The gut microbiota is influenced by environmental and nutritional factors and plays a role in human health through several mechanisms, including the production of bioactive compounds, protection from pathogens, energy homeostasis, and regulation of immunity.

The ketogenic diet is a very popular dietary approach used for different purposes, from weight loss to treating neurological diseases. It involves a very low consumption of carbohydrates (around 5% to 10% of total caloric intake or below 50 g per day) and a high consumption of fats (60% to 90% of total caloric intake).

The ketogenic diet has a significant impact on the gut microbiome, with studies showing a reduction in the total bacterial count and a decrease in the abundance of certain bacteria, such as Bifidobacterium, Roseburia, and Eubacterium rectale. The diet also leads to a reduction in short-chain fatty acids (SCFAs), which are important for maintaining gut health and have anti-inflammatory properties.

The decrease in Bifidobacterium is of particular interest as this genus of bacteria is important for colonic health and has anti-inflammatory properties. The reduction in Bifidobacterium may be due to the low intake of carbohydrates in the ketogenic diet, as this type of bacteria relies on carbohydrates as its energy source.

Additionally, the ketogenic diet may have a biphasic effect on the gut microbiome, with an initial decrease in bacterial richness and diversity, followed by a recovery and potential increase after several weeks.

Overall, the ketogenic diet has a complex and dynamic impact on the gut microbiome, and more research is needed to fully understand its effects and potential therapeutic benefits.

The link between keto and other skin conditions

The ketogenic diet has been linked to a rare skin condition called prurigo pigmentosa, commonly referred to as "keto rash". It is characterised by a red, itchy rash that occurs primarily on the upper back, chest, and abdomen, with red spots that take on a web-like appearance. This condition is associated with the ketogenic diet and is thought to be linked to ketosis, the metabolic state that the body enters when following a ketogenic diet. The exact cause of keto rash is not yet known, but it is believed to be associated with nutritional and hormonal deficiencies.

The ketogenic diet has also been linked to improvements in other skin conditions such as acne. By cutting out simple carbohydrates, the diet targets the body's excess inflammation, which is a significant promoter of acne. Additionally, the omega-3 fatty acids found in many keto-friendly foods such as salmon and walnuts may help soothe dry, itchy, and scaly skin. However, the high consumption of dairy products on a keto diet may be problematic for some, as dairy is known to trigger acne in some individuals.

While the ketogenic diet has shown potential for improving certain skin conditions, it is important to note that it may also have negative effects on the skin. Some people who follow the keto diet experience a strange, itchy red rash across their torsos. This side effect is known as keto rash, and it is believed to be caused by the body entering a state of ketosis. Keto rash usually affects the upper body and can be treated by reintroducing carbohydrates into the diet, as this moves the body out of ketosis.

Overall, the ketogenic diet has been linked to both improvements and negative effects on the skin. While it may help reduce acne and improve certain skin conditions, it can also cause keto rash in some individuals. More research is needed to fully understand the link between the ketogenic diet and skin health.

The role of nutrition in eczema management

Eczema is an inflammatory skin disease that affects about 31.6 million people in the United States alone. It is more prevalent in children, but adults can develop it too, even without any personal or family history of the condition. The exact cause of eczema is unclear, but it is believed to be a combination of environmental triggers and genetics.

The standard treatment options for eczema include injectable biologics and phototherapy (light therapy). However, many people are now turning to alternative and lifestyle therapies, such as probiotics and fermented foods, and daily bathing and moisturising routines.

The role of nutrition in managing eczema is an important one, and certain diets are believed to help alleviate symptoms. The ketogenic diet, in particular, has gained attention as a possible therapeutic option for eczema.

The Ketogenic Diet

The ketogenic diet is a low-carbohydrate, high-fat, moderate-protein diet. It has been studied and used in the management of various conditions, including certain types of epilepsy and weight loss.

The diet works by altering the body's energy metabolism, and it has been shown to have anti-inflammatory effects. This is particularly relevant for eczema, as it is an inflammatory skin disease.

Keto and Eczema

There is some evidence to suggest that a ketogenic diet can help improve eczema symptoms. Firstly, by reducing inflammation, the diet may help to alleviate the itching and redness associated with eczema. Secondly, by eliminating sugar and refined carbs, the diet can help balance the gut microbiome, which is often disrupted in people with eczema.

Additionally, the ketogenic diet includes foods rich in omega-3 fatty acids, such as fatty fish, nuts, and seeds, which are known to have anti-inflammatory properties and may help improve eczema symptoms.

However, it is important to note that the ketogenic diet also includes some foods that can trigger eczema flare-ups, such as eggs and tomatoes. Furthermore, eliminating certain food groups can lead to nutritional deficiencies that may negatively impact skin health.

While there is some promising evidence, more long-term studies are needed to fully understand the effects of a ketogenic diet on eczema.

Other Diets

Other diets that have been explored for eczema management include the paleo diet and a gluten-free diet. The paleo diet, which includes lean meats, fish, fruits, vegetables, and nuts, can help clean up the gut and reduce eczema symptoms. However, it may not address all the factors contributing to eczema flare-ups.

A gluten-free diet has yielded mixed results, with some people experiencing a significant reduction in eczema flare-ups, while others see no improvement. This is because eczema can be correlated with allergic reactions to various environmental factors, which differ from person to person.

While there is no one-size-fits-all approach to treating eczema, nutrition plays a crucial role in managing the condition. The ketogenic diet has shown some promise in improving eczema symptoms, primarily due to its anti-inflammatory effects and positive impact on the gut microbiome. However, more research is needed to confirm these findings.

It is always recommended to consult with a healthcare professional or dermatologist before making any significant dietary changes to treat eczema.

The potential risks of a keto diet

The keto diet has been studied in the context of several conditions, and while it is most commonly used to help control epilepsy, it has also gained traction as a weight-loss strategy. However, there are several potential risks associated with the keto diet that should be carefully considered.

Firstly, the keto diet may lead to the "keto flu," which includes symptoms such as headaches, dizziness, fatigue, nausea, and constipation due to dehydration and electrolyte imbalances. While these symptoms typically subside within a few weeks, staying hydrated and consuming electrolytes are crucial during this adjustment phase.

Secondly, the keto diet may stress your kidneys. The high intake of animal foods, such as eggs, meat, and cheese, can cause your blood and urine to become more acidic, leading to increased calcium excretion in the urine and a higher risk of kidney stones. The keto diet may also worsen chronic kidney disease (CKD) by causing acid buildup in the blood, leading to a state of acidosis.

Thirdly, the keto diet can cause digestive issues and negatively impact gut health. The restriction of carbohydrates makes it challenging to meet daily fiber needs, and the elimination of high-fiber foods can lead to constipation and negative changes in gut bacteria.

Fourthly, the keto diet may lead to nutrient deficiencies, particularly of calcium, vitamin D, magnesium, and phosphorus. Over time, this can result in various health issues, and it is important to ensure adequate nutrient intake or consider supplementation under medical guidance.

Fifthly, the keto diet may cause dangerously low blood sugar levels in individuals with type 1 diabetes, increasing the risk of hypoglycemia, which can have severe consequences if left untreated.

Lastly, the keto diet has been associated with impaired bone health in several studies. Animal studies have linked the keto diet to decreased bone strength and reduced bone mineral density, which may occur as the body adapts to ketosis.

It is important to note that the potential risks of the keto diet may vary depending on individual factors, and consulting with a healthcare professional before starting any dietary changes is strongly advised.
