Keto Diet: Can It Change Vaginal Odor?

The keto crotch phenomenon has been anecdotally reported by women following a ketogenic diet. The term refers to an increase in vaginal discharge and a stronger vaginal odour. While there is little scientific research on the topic, a potential link between the keto diet and keto crotch could be the impact of the diet on vaginal pH levels, which can lead to bacterial vaginosis (BV). A healthy vaginal pH is acidic and falls between 3.8 and 4.5 on the pH scale. Research suggests that a diet high in fat, particularly saturated fat, can alter these pH levels, creating an environment conducive to bacterial growth.

Keto crotch: what is it?

"Keto crotch" refers to an unusual odor emanating from the vaginal area after starting a ketogenic diet. The phenomenon has been reported by several women online, especially on Reddit, and some have also reported experiencing a rash in the crotch area.

The ketogenic diet, or keto diet, is a high-fat, low-carb, and moderate-protein diet that induces ketosis in the body. This means that the body breaks down fat for energy instead of carbohydrates, resulting in weight loss. While the keto diet has gained popularity for its weight loss benefits, it also comes with a range of side effects, including "keto flu," "keto breath," and now, "keto crotch."

Keto crotch is characterised by a noticeable change in vaginal odour, often described as a sour or fishy smell, and sometimes accompanied by unusual discharge. These symptoms typically appear after about a month of starting the keto diet and can range from mild to very unpleasant.

So, what causes keto crotch? Well, the exact cause is not yet fully understood, but it is likely related to the metabolic changes that occur when the body enters ketosis. As the body breaks down fat, it produces ketones, including acetone, which is also found in nail polish remover and is responsible for the distinctive smell of "keto breath." It is thought that the build-up of acetone in the body may be a contributing factor to the altered vaginal odour experienced during keto crotch.

In addition, the keto diet's high-fat content can impact vaginal pH levels, creating an environment conducive to the growth of certain microorganisms, such as bacteria or yeast. Bacterial vaginosis (BV) can develop as a result of this imbalanced vaginal pH, leading to an unpleasant odour.

While there is limited scientific research on keto crotch specifically, the link between high-fat diets and BV has been explored in some studies. For example, a 2007 study found that participants who consumed a high-fat diet had an average vaginal pH of 5.1, which is higher than the typical vaginal pH of 3.8 to 4.5. Additionally, a 2020 review reinforced the connection between high-fat diets and the occurrence of BV, particularly highlighting the role of saturated fats.

It is important to note that keto crotch may not be a direct result of the keto diet itself, but rather a combination of factors, including previous diet, hormonal factors, and individual metabolism, which can influence how sensitive the body is to diet-related pH changes.

If you are experiencing keto crotch, there are some steps you can take to reduce the symptoms. Firstly, ensure you are consuming enough carbohydrates, as very low-carb intake can increase keto-related body odours. Keep your net carb intake between 20 to 50 grams daily to maintain ketosis and minimise side effects. Secondly, incorporate plenty of green leafy vegetables into your diet, as they are rich in chlorophyll, a natural "internal deodorizer" that can help with keto-related body odours.

It is also important to note that vaginal health does not require the use of douches or soaps, as these can disrupt the vaginal pH and increase the risk of bacterial vaginosis and yeast infections.

While keto crotch may be an unpleasant side effect of the keto diet, it is not permanent. As your body adjusts to burning fat, the symptoms of keto crotch should subside, and you can take proactive measures to speed up this process and minimise odours.

Why does keto cause this?

While there has not been any scientific investigation into "keto crotch", there are a few reasons why the keto diet may cause an increase in vaginal odor.

Firstly, the keto diet may alter the vaginal pH, making it more alkaline. A healthy vaginal pH is typically on the acidic end of the spectrum (3.5 to 4.5 pH), which helps prevent the growth of certain microorganisms. However, when in ketosis for an extended period, the ketones produced and the types of food consumed on the keto diet (such as meats, poultry, dairy, and animal fats) can change the vaginal pH. This alteration in pH can allow for the overgrowth of bacteria, leading to an infection known as bacterial vaginosis (BV). BV is characterized by a strong vaginal odor and discharge, which may be what is referred to as "keto crotch".

Secondly, the keto diet may affect the gut microbiome. Research suggests that high-fat diets can alter the composition of the gut microbiome for the worse. Since the gut microbiome may function as a reservoir for vaginal microorganisms, maintaining a healthy and balanced gut microbiome is crucial for vaginal health. A balanced gut microbiome can be supported by consuming probiotic-rich foods, such as yogurt, kimchee, and sauerkraut, as well as prebiotics like garlic, leeks, onions, and fiber-rich foods.

Additionally, it is important to note that the keto diet can lead to other side effects, such as "keto flu" and "keto breath", which are caused by the production of ketones and the reduction in carbohydrate intake.

How to get rid of keto crotch

Keto crotch refers to a temporary change in vaginal odor in women who follow a ketogenic diet. While there is no scientific research confirming that keto crotch is a side effect of the keto diet, some women have reported experiencing a stronger vaginal odor and discharge. This could be due to a change in vaginal pH, which can lead to bacterial vaginosis (BV).

Understand the Role of Vaginal pH:

Vaginal pH refers to the acidity or alkalinity of the vagina. A healthy vaginal pH is typically between 3.8 and 4.5, which is on the acidic side. This acidic environment helps prevent the growth of certain microorganisms and maintains a healthy vaginal microbiome. However, when the vaginal pH increases (becomes more alkaline), it can allow for the overgrowth of bacteria, potentially leading to BV.

Adjust Your Diet:

One way to address keto crotch is to adjust your diet to promote a healthy vaginal pH. Here are some dietary recommendations:

• Incorporate more alkaline foods: Include more alkaline foods in your keto diet to help balance your vaginal pH. Alkaline foods include leafy greens, non-starchy vegetables like broccoli, cabbage, and Brussels sprouts, plant-based fats like avocados, coconut oil, and olive oil, as well as some fruits.
• Reduce acidic foods: Cut back on highly acidic foods, especially animal-based fats and proteins. These include meats, poultry, dairy, and animal fats like butter.
• Focus on plant-based sources of fat: The keto diet often displaces plant-based foods with animal-based ones. Plant-based fats and high-fiber foods are important for feeding good bacteria in the gut and maintaining a healthy vaginal pH.
• Consider a moderate approach: Instead of strictly limiting carbohydrates, try a more moderate approach by consuming slightly more carbs than the keto diet typically allows. This can help improve vaginal and gut health.

Support Your Gut Health:

The health of your gut and vagina are interconnected. Supporting the growth of good bacteria in your gut can positively impact your vaginal health. Here are some tips:

• Incorporate probiotic-rich foods: Include probiotic-based foods in your diet, such as yogurt, kimchi, and sauerkraut. These foods help promote a healthy vaginal pH and support your immune function.
• Consume prebiotic foods: Prebiotics feed the good bacteria in your gut. Include prebiotic foods like garlic, leeks, onions, and a variety of fiber-rich foods in your diet.

Practice Good Vaginal Hygiene:

• Avoid douching: Douching can disrupt the natural balance of bacteria in the vagina and make the issue worse. The vagina is self-cleansing, so there is no need to douche.
• Use natural topical products: If you want to counter vaginal odor, opt for natural topical products like coconut oil, which has antibacterial and antifungal properties.

Consult a Healthcare Professional:

If the odor persists or is accompanied by other symptoms like itchiness, burning, or abnormal discharge, consult your doctor or gynecologist. They can help determine the underlying cause and provide appropriate treatment options.

While keto crotch may be an unpleasant side effect of the keto diet, making these dietary and lifestyle adjustments can help address the issue and promote better vaginal and overall health.

Keto crotch: a female-only phenomenon?

Keto crotch is a term used to describe an increase in vaginal discharge and odour while following the keto diet. While there is limited scientific research on the topic, many women have reported experiencing keto crotch, with some taking to online forums such as Reddit to share their stories.

The keto diet is a high-fat, low-carbohydrate diet that has become increasingly popular in recent years. It involves restricting your carbohydrate intake to just 5-10% of your calories, which means your body enters a state of ketosis, burning fat instead of glucose for energy. While this can lead to weight loss, the keto diet also comes with a range of side effects, including keto flu, keto breath, and keto diarrhoea.

So, is keto crotch one of them? Well, it's possible. One theory is that the keto diet impacts your vaginal pH, which can then change the odour. A healthy vaginal pH is acidic and falls somewhere between 3.8 and 4.5 on the pH scale. Foods like onions, garlic, red meat, dairy, asparagus, broccoli, alcohol, and fruit can all affect this natural balance. Even a slight change in pH can alter the smell you're used to.

Another theory is that keto crotch is linked to elevated levels of ketones, specifically acetone, in the body. As you enter ketosis, your body breaks down fat for energy and produces ketones as by-products. Acetone is the same chemical that gives nail polish remover its pungent smell, and it can accumulate in your system, leading to changes in body odour, including your breath and likely your vaginal odour.

It's worth noting that keto crotch may not be a female-only phenomenon. Some men have reported experiencing symptoms similar to keto crotch, such as temporary changes in body odour. The male groin area contains a lot of sweat glands, which can further contribute to an unpleasant crotch odour.

While there is no definitive answer yet as to whether keto crotch is a real side effect of the keto diet, it's important to remember that any unusual odour could be a sign of an infection or other condition that requires medical attention. If you notice any sudden or worrying changes, it's best to consult a doctor.

Other keto side effects

The keto diet can cause a host of other side effects, some of which are short-term and others that can be more long-lasting.

Keto Flu

The keto flu is a common side effect, which involves a range of flu-like symptoms, including:

• Headaches
• Dizziness
• Insomnia
• Fatigue
• Nausea
• Body aches

These symptoms typically last anywhere from 24 hours to two weeks as your body adjusts to ketosis.

Keto Breath

Keto breath is another recognised side effect of the keto diet. It is caused by the buildup of acetone in the body, which is a type of ketone produced during ketosis. Acetone is also found in nail polish remover and can cause your breath to have a fruity or chemical smell.

Kidney Stones and Vitamin/Mineral Deficiencies

The keto diet can also have long-term consequences, including kidney stones, vitamin deficiencies, and mineral deficiencies.

Rash

Some people on the keto diet have also reported developing a rash, known as keto rash or prurigo pigmentosa. This typically appears as red, itchy bumps on the neck, back, and stomach, though it is not directly linked to the diet.

Diarrhea

The high-fat content of the keto diet can also cause diarrhea, especially when coupled with the use of artificial sweeteners.

Weight Loss

The keto diet is often undertaken to aid weight loss, and research has shown that people on the keto diet may lose weight after maintaining ketosis for 12 months. However, early weight loss on the keto diet may be water weight loss, and some evidence suggests that weight loss may be due to eating fewer calories, rather than ketosis itself.

Other Health Benefits

The keto diet has also been linked to other health benefits, such as managing type 2 diabetes and preventing chronic illnesses like cancer, Alzheimer's disease, and non-alcoholic fatty liver disease.

Safety Concerns

However, it is important to note that the keto diet may be unsafe for people with type 1 diabetes or during pregnancy. Additionally, restricting your carb intake may lead to nutrient deficiencies, as carb sources like fruits, milk, and whole grains contain essential nutrients like calcium, fibre, potassium, and vitamin D.

While the keto diet has its benefits, it is always recommended to consult a healthcare provider before starting any new diet, including keto.
