Keto And Skin Breakouts: Is There A Connection?

The ketogenic diet is a popular choice for those looking to lose weight, but its high-fat content can have a detrimental effect on skin health. Anecdotal evidence from dermatologists, facialists, and nutritionists suggests that the keto diet can cause breakouts, with some reporting that it worsened their skin. However, there is also evidence to suggest that the keto diet can improve skin health and reduce acne. So, what's the truth?

High-calorie diets

The keto diet, in particular, can be a high-calorie diet as it often involves consuming more calories than usual, especially from high-fat foods. This increase in fat intake can lead to digestive issues, changes in the microbiome, and increased sebum production, all of which can impact the skin and contribute to breakouts.

However, it is important to note that not all high-calorie foods will necessarily cause breakouts. For example, healthy high-calorie foods such as avocados, nuts, and olive oil are less likely to cause acne. Instead, it is the high-calorie, highly processed, and high-glycemic index foods that are more likely to lead to skin problems. These types of foods can cause gut imbalances and liver congestion, which can overload the body and lead to congestion in the skin, resulting in breakouts.

Additionally, a high-calorie diet may also be lacking in important nutrients that are beneficial for the skin, such as vitamins C, E, and A, which are typically found in plant foods. A balanced diet that includes a variety of whole foods, including nutrient-rich, low-carb vegetables, is recommended for maintaining clear skin.

High leucine content

Leucine is an amino acid that is found in meat and dairy proteins. A diet high in leucine can cause acne. Leucine activates mTORC1, a signalling protein that is known to activate pro-inflammatory nuclear factor κB signalling, possibly aggravating the inflammation implicated in acne. Leucine also stimulates mTORC1-SREBP signalling and is directly converted by sebocytes into fatty acids and sterols for sebaceous lipid synthesis. Leucine is a precursor of sebaceous lipids.

Leucine-rich diets, such as those that include a lot of meat and dairy, can provide leucine as a structural lipid precursor for de novo sebaceous lipid synthesis. Leucine-enriched animal-derived foods include gouda cheese, curd cheese, cow's milk, whey protein concentrate and steak. Leucine-enriched plant-derived foods include cauliflower and white cabbage.

Leucine is the most effective essential amino acid required for mTORC1 activation. Leucine exerts the greatest effects on mTORC1 signalling out of all essential amino acids. Leucine-induced S6K phosphorylation was inhibited by N-acetylleucine amide (NALA), which also inhibited leucine-induced amino acid-mTORC1 signalling in Jurkat cells. Leucine is converted into lipids (fatty acids and cholesterol) and stored in adipose tissue. Leucine can be converted into lipids by sebaceous glands. Leucine-enriched Western diets may have two major effects on sebaceous lipogenesis: to increase leucine-stimulated mTORC1/SREBP signalling, thus driving the genetic program of sebogenesis, and to provide leucine as a structural lipid precursor for de novo sebaceous lipid synthesis.

Acidic pee

Keto and Acidic Pee

The ketogenic diet can increase the acidity of urine. Ketones are an acid, and the production of ketones is a sign that the body is in a state of ketosis, which is the goal of the keto diet. While the keto diet has benefits such as weight loss and reduced hunger, it can also cause breakouts and skin issues for some people.

The keto diet involves eating a lot of fat and very few carbohydrates. This shift in diet causes the body to burn fat instead of carbohydrates for energy, resulting in the production of ketones. An increased level of ketones in the body can lead to a more acidic pH level in the urine.

The Impact of Acidic Pee on Breakouts

When the urine becomes more acidic, the body may reabsorb certain compounds that it originally intended to get rid of. This can include salicylates, which are linked to increased inflammation in the body. As acne is an inflammatory skin condition, this can lead to breakouts or make existing acne worse.

How to Address Acidic Pee on Keto

To reduce the acidity of urine while on the keto diet, it is recommended to cut down on meat consumption. Meat is a major contributor to acidic urine, and reducing intake can help balance the body's pH levels. Additionally, focusing on a clean" keto diet that emphasizes whole foods and healthy fats, as well as staying hydrated, can help improve skin health.

It is important to note that everyone's experience with the keto diet may vary, and while some people may experience skin issues, others may find that their skin improves.

High-fat diets

Firstly, high-fat diets have been linked to an increase in the production of sebum, a natural skin oil. This can block your pores and give you acne. A 2015 study found that high-fat diets increased the production of sebum, which can increase your risk of acne.

Secondly, a high-fat diet can cause digestive issues, which can also lead to breakouts. If your system gets blocked up with too much fat, your body will try to eliminate it through the skin, which can result in cystic acne and darkened under eyes.

Thirdly, the keto diet can be stressful on the body, especially at the beginning. This stress can cause an inflammatory reaction, which can worsen the inflammation that accompanies more severe acne outbreaks.

Finally, the keto diet is low in fibre and vitamins and minerals that are important for skin health, like vitamins C, E, and A.

However, it is important to note that the link between diet and acne is complicated and still hotly debated by scientists. While some people may experience breakouts from the keto diet, others may find their skin looks better than ever.

High dairy intake

Dairy products such as aged cheeses and sour cream are allowed in small amounts on the keto diet. However, it is worth considering whether avoiding all dairy can help improve skin concerns. Dairy products and oils have been linked with acne. They can cause your body to produce more sebum, a natural skin oil that can block your pores and give you acne.

A 2015 study found that high-fat diets increased the production of sebum on the skin, which can increase your risk of acne. Additionally, a 2007 study found that higher-fat diets were associated with higher levels of a specific marker for inflammation, known as the C-reactive protein. Translation: high-fat diets may increase inflammation in the body, which has been linked to skin conditions like acne, psoriasis, and eczema.

The keto diet can also cause a red and itchy skin rash called prurigo pigmentosa, or the keto rash. While the cause of this is not understood, it can be treated using skin products like moisturisers, and even with antibiotics.

If you are experiencing acne breakouts, it is recommended to limit lactose and consider seeing a dermatologist.
