Keto And Acne: Is There A Link?

The ketogenic diet is a high-fat, low-carb diet that encourages the body to enter a metabolic state called ketosis, in which fats are converted into ketones, which become the body's primary source of energy. While some people claim that the keto diet can help with weight loss, it has also been associated with several negative side effects, including acne breakouts. The keto diet can be particularly stressful on the body, causing various issues such as bad breath, constipation, and skin inflammation, which can lead to acne.

The high-fat content of the keto diet is believed to be a key factor in acne development. A 2015 study found that high-fat diets increased sebum production, which can contribute to acne. Additionally, high-fat diets have been linked to increased inflammation in the body, which is a known driver of skin conditions like acne.

However, the relationship between the keto diet and acne is complex and may vary from person to person. While some individuals may experience acne breakouts while on the keto diet, others may find that their skin clears up. This may be due to the keto diet's ability to reduce insulin levels and related hormones, which can help regulate sebum production and improve skin health.

To summarize, while the keto diet has the potential to cause acne breakouts due to its high-fat content and metabolic effects, it may also have beneficial effects on skin health for some individuals. The impact of the keto diet on acne is likely influenced by various factors, including individual differences in physiology, diet composition, and overall nutritional intake.

High-calorie diets and keto acne

While keto diets are low-carb, they are also high-fat and high-calorie. This can have a negative impact on your skin, causing breakouts and acne.

The keto diet encourages the body to enter a state of ketosis, where the body converts fats into ketones. This usually happens between day three and seven of starting the diet, when the body starts producing ketones in place of regular sugars.

According to dermatologist Ross C. Radusky, any change in diet can cause inflammation, especially one that turns the usual percentages of fats, carbohydrates, and proteins upside down.

High-calorie diets and acne

A high-calorie diet can cause acne because it opens a biological door called mTORC-1. This senses how much energy you are giving your body. If you give your body a lot of energy, mTORC-1 opens and your body goes into hypermode, making things grow and repair. This is bad for acne-prone skin because acne is caused by an overgrowth of skin cells inside your pores, which clog them.

How to avoid keto acne

To avoid acne caused by a high-calorie keto diet, it is recommended to not go crazy on high-calorie foods and to eat a good amount of nutrient-packed, low-carb veggies.

High leucine content and keto acne

High leucine content in the diet is a major factor in the development of acne. Leucine is an essential amino acid, and a key component of many proteins. It is found in high levels in meat and dairy products, and is also added to many protein supplements. Leucine activates the mTORC1 pathway, which is a key regulator of cell growth and proliferation. This pathway is also activated by insulin and IGF-1, and is associated with increased sebum production, which is a key factor in the development of acne.

The Western diet is characterised by high levels of leucine, due to the high consumption of meat and dairy products, and this is thought to be a major factor in the development of acne. Leucine-rich diets have been shown to increase the incidence of acne, and acne has been shown to improve when meat and dairy consumption is reduced.

Ketogenic diets and inflammation

The ketogenic diet is a high-fat, low-carbohydrate regimen that has been used to treat epilepsy and other neurological illnesses for many years. This diet changes the way the body uses energy, forcing it to break down fats into ketones and keto acids to be used as alternative fuels. While the ketogenic diet is difficult to maintain, it has been shown to have anti-inflammatory effects in the brain and body.

Inflammation and the Brain

Research by UC San Francisco scientists has found that ketogenic diets may work by lowering inflammation in the brain. The study, conducted on rats, discovered that a low-carbohydrate diet reduces inflammation by lowering a key barometer of energy metabolism, which in turn activates a protein that suppresses the activity of inflammatory genes.

Inflammation and the Body

Ketogenic diets have been shown to reduce inflammation in the body, specifically in the case of pain and painful or progressive conditions. A 2009 study found that a ketogenic diet reduced pain and inflammation in juvenile and adult rats. The diet also produced long-recognized changes in blood chemistry, including elevated ketones and lowered glucose.

Ketogenic Diets and Thermal Pain

A 2013 study on rats found that a ketogenic diet increased the latency to show behavioural indications of pain, or thermal hypoalgesia. The study also found that this effect was present in both juvenile and adult rats, and that the diet did not impact motor function.

Ketogenic Diets and Neuropathic Pain

Neuropathic pain is caused by lesions or dysfunction of nervous tissue and is often associated with diabetes, shingles, multiple sclerosis, and certain drugs. A 2009 study on mice found that a ketogenic diet had little effect on neuropathic pain due to sciatic nerve constriction injury. However, the study also noted that initiating the diet after the injury may have reduced its potential efficacy, and that pre-treatment with a ketogenic diet may yield different results.

Ketogenic Diets and Inflammatory Markers

A 2018 study found that the ketogenic diet may reduce inflammation by decreasing the activity of the nervous system and reactive oxygen species, which are known to contribute to inflammation. The diet may also increase adenosine, a natural chemical that fights inflammation and acts as a pain reliever.

Carbohydrates and Inflammation

Excess carbohydrates are broken down into sugars, which can cause glucose to build up in the blood and lead to inflammation. Chronic inflammation can result in serious problems like insulin resistance and type 2 diabetes.

Anti-Inflammatory Ketogenic Foods

While the ketogenic diet itself is anti-inflammatory, certain foods are better for fighting inflammation. These include healthy fats like egg yolks, nuts, seeds, and fatty fish; omega-3 fats; healthy meats like grass-fed beef and lamb; and non-starchy vegetables like dark leafy greens.

Inflammatory Foods to Avoid

To reduce inflammation, it is best to avoid processed and high-glycemic foods, refined vegetable oils, and coffee and alcohol.

Ketogenic diets and insulin levels

Insulin is a protein-based hormone produced by beta cells located in the pancreas. Its primary purpose is to regulate the metabolism of fats and carbohydrates. Insulin resistance is a condition in which cells throughout the body no longer respond to the normal actions of the hormone insulin.

Ketogenic Diets and Insulin Resistance

Ketogenic diets have been shown to be effective in lowering insulin resistance. In a 2005 study, 10 obese patients with type 2 diabetes were placed on a high-fat ketogenic diet for 2 weeks. The subjects experienced a 30.4% decrease in mean energy intake, resulting in a weight loss of 1.65 kg. More significantly, insulin sensitivity improved by approximately 75%.

Another study in 2006 divided 83 subjects into three groups, with each group consuming one of three equal-calorie diets: a very low-fat diet (70% carbohydrates), a diet high in unsaturated fat (50% carbohydrates), and a very low-carbohydrate ketogenic diet (4% carbohydrates). After the intervention, the researchers noted that each diet led to similar reductions in weight loss and fat loss composition. However, the ketogenic diet lowered fasting insulin by 33%, while the diet high in unsaturated fat lowered it by 19%.

Ketogenic diets have been found to decrease insulin levels, often dramatically. In a 2007 study, a low-glycemic-load diet was found to improve symptoms in acne vulgaris patients compared to a high-glycemic-load diet. The low-glycemic-load group experienced a decrease in androgen and insulin levels, improvement in insulin sensitivity, and weight loss. By contrast, the high-glycemic-load group had increases in weight, insulin levels, and insulin resistance.

Ketogenic Diets and Inflammation

Ketogenic diets have also been shown to reduce inflammation, which drives acne progression. A 2008 study found that low-fat and low-carbohydrate diets reduced inflammation markers. Additionally, a 2012 article by Italian researchers discusses the potential benefits of ketogenic diets for acne, including lower insulin levels, anti-inflammatory effects, and a decrease in IGF-1 (insulin-like growth factor 1).

In conclusion, ketogenic diets have been shown to be effective in lowering insulin resistance and decreasing insulin levels. Additionally, the anti-inflammatory effects of ketogenic diets may also be beneficial for acne-prone skin. However, it is important to note that there are also potential negative side effects of ketogenic diets, such as increased inflammation and dehydration, which can negatively impact the skin.

Ketogenic diets and skin hydration

The ketogenic diet is a high-fat, low-carb diet that encourages the body to enter a metabolic state called ketosis, where fats are converted into ketones, which become the body's main source of energy. While the keto diet has become popular for weight loss, its effects on skin health are less certain. Some people report clearer skin while others experience increased acne or skin irritation.

The Impact of Ketogenic Diets on Skin Hydration

The keto diet can be dehydrating, causing skin cells to shrink, which can lead to dry and irritated skin. This is due to the water weight loss associated with ketosis. However, the diet's impact on skin hydration may also be influenced by the types of fats and carbohydrates consumed.

The Role of Carbohydrates

Simple carbohydrates, such as white bread, white pasta, cookies, and cake, can contribute to inflammation in the body, which is a key promoter of acne. By eliminating these types of carbs, the ketogenic diet can help reduce inflammation and improve skin health.

The Role of Fats

The keto diet's high-fat content can increase the production of sebum, an oily substance that lubricates the skin and hair. While this can be beneficial for skin hydration, excess sebum can also contribute to acne. Additionally, high-fat diets have been linked to increased inflammation, which can lead to skin conditions like acne, psoriasis, and eczema.

Managing Skin Hydration on a Ketogenic Diet

To maintain skin hydration while on the keto diet, it is recommended to increase water intake. Additionally, avoiding high-lactose foods, using acne-specific cleansers, and incorporating hydrating skincare products can help manage skin health.

Overall Impact on Skin Health

The impact of the ketogenic diet on skin hydration and overall skin health varies from person to person. While it has the potential to clear acne, it may also cause skin irritation and dryness. Consulting with a dermatologist before starting the keto diet is recommended to ensure it is safe and appropriate for your skin concerns.
