Keto Body Odor: Why It Happens And How To Fix It

The ketogenic diet is a high-fat, low-carb diet that induces ketosis, causing a loss of appetite and leading to weight loss. However, ketosis has several unpleasant side effects, including body odour and bad breath, often referred to as keto breath. The fruity, nail-polish-remover-like smell comes from the acetone, a type of ketone, that is released from the body through breath, urine and sweat. While the odour is usually temporary, there are several ways to reduce it, including drinking more water, showering more frequently, and reducing protein intake.

Ketone bodies are excreted through urine, breath and sweat, causing a fruity, acidic smell

When your body enters ketosis, it starts producing ketone bodies. Fatty acids are converted into ketones, which are natural chemicals your body produces when you enter ketosis. The three ketone bodies your body produces are hydroxybutyrate, acetoacetate, and acetone.

In the beginning, your body has just started producing ketone bodies and is still adapting. This means that your body is slowly adapting and learning to burn fat for energy, but it isn't very effective at the beginning. That's why a large amount of ketone bodies will be excreted by urine, breath, and sweat.

The interesting thing is that ketone bodies do have a smell, and it's not a pleasant one. If you are in ketosis, you are excreting acetone and acetoacetone from your body in noticeable amounts through your breath, urine, and skin. That's why this smell has often been described as fruity and acidic, and reminds people of the chemical acetone.

The level of the smell depends on the person and the level of how many ketone bodies they produce. During the time it will get better at using ketone bodies as fuel, and it will fade away. Once you are keto-adapted, everything will be normal again.

Detoxing: toxins are released into the bloodstream and excreted through sweat

The ketogenic diet is a very low-carb, high-fat, and moderate-protein diet. When you start a ketogenic diet, your body will enter a state of ketosis, where it burns fat for energy instead of carbohydrates. This can lead to a build-up of ketones in the body, which are natural chemicals produced when you enter ketosis. While ketosis can have many benefits, it can also lead to a phenomenon known as "keto breath," where the ketones are excreted through the breath and give off a fruity or metallic smell.

Additionally, the ketogenic diet can also lead to a process known as "detoxing." This is because toxins, such as environmental pollutants, can be stored in fat cells, and when you burn fat on the keto diet, these toxins are released into the bloodstream and excreted through sweat. This can result in an unusual body odour, often described as a strong, musky, or urine-like smell. The detox process can also cause other side effects, such as fatigue, flu-like symptoms, joint pain, skin breakouts, sinus problems, and gut issues.

The good news is that the detox process is usually temporary, and the side effects will subside as your body becomes keto-adapted. However, there are some things you can do to support your body during this process:

• Drink enough water to stay hydrated.
• Increase your fibre intake to ensure regular bowel movements, as this is crucial for eliminating toxins from the body.
• Eat plenty of anti-inflammatory fats, such as omega-3s from oily fish or fish oil, and olive and avocado oils.
• Consume sulfur-rich foods like broccoli, cabbage, cauliflower, Brussels sprouts, and eggs to support the second phase of detoxification.
• Get enough sleep, as many of the body's detoxification processes occur during sleep.
• Reduce your alcohol intake, as this can affect your liver's ability to process toxins.
• Cut down on added sugars, as they have been shown to increase fat production in the liver, leading to compromised liver function.
• Use natural or chemical-free cleaning and personal care products to reduce your exposure to toxins.
• Choose organic and non-GMO foods when possible to minimise your intake of pesticides and agricultural chemicals.

Excess protein in the body can result in the smell of ammonia

The human body produces ammonia when it breaks down protein into amino acids. The liver then converts the ammonia into urea, which is expelled from the body through urine or sweat. However, if there is an excess of protein in the body, it can result in the buildup of ammonia, leading to an unpleasant ammonia odour.

The keto diet is a high-fat, moderate-protein, and low-carb diet. While it is generally recommended to keep protein intake moderate, some individuals may accidentally consume more protein than necessary. This is especially true for those new to the diet, as they may not yet fully understand the appropriate proportions of macronutrients.

When there is an excess of protein in the body, and not enough carbohydrates to meet the body's energy needs, the body will turn to protein metabolism. This process can result in the production of ammonia, which the liver may struggle to convert into urea at the same rate. As a result, the excess ammonia may be excreted through sweat, leading to an ammonia odour.

The smell of ammonia is often described as similar to urine or sweat and can be quite strong and unpleasant. It is important to note that ammonia-scented sweat is not considered normal or healthy. If you notice that your sweat smells like ammonia, it may be a sign that your diet needs adjustment.

To address the issue of excess ammonia odour, it is recommended to reduce your protein intake to 10-15% of your total calorie intake and increase your consumption of healthy fats. Additionally, ensure that you are staying hydrated and including high-fibre vegetables and leafy greens in your diet. By making these adjustments, you should be able to reduce the ammonia odour and maintain a healthy balance in your keto diet.

Keto breath: acetone, a type of ketone, is released through the breath

The ketogenic (keto) diet is a high-fat, low-carbohydrate diet that has gained popularity for its significant health benefits. However, it can also lead to some unpleasant side effects, including "keto breath".

Keto breath is characterised by a fruity, metallic, or chemical smell, similar to nail polish remover, which is caused by the release of acetone, a type of ketone, through the breath. This occurs when the body enters a state of ketosis, where it burns fat instead of glucose for energy. During ketosis, the body breaks down fat in the liver, converting it into ketones, including acetone, which are then transported to the brain to be used as energy.

While in ketosis, the body may initially excrete large amounts of ketones through the breath, urine, and sweat, leading to keto breath. This is particularly noticeable in the beginning stages of the keto diet, as the body is still adapting to using fat for energy. However, as the body becomes more efficient at utilising ketones, the side effect of keto breath should diminish over time.

To help alleviate keto breath, it is recommended to:

• Drink more water to stay hydrated, as dry mouth can exacerbate the issue.
• Increase physical activity to burn off excess ketones.
• Consume less protein, as ammonia, a byproduct of protein breakdown, can contribute to the unpleasant odour.
• Be patient, as keto breath is a sign that the body is not yet fully fat-adapted, and it should improve as the body adjusts to using ketones for fuel.

Keto crotch: the keto diet may be causing a change in vaginal acidity, leading to a stronger odour

The keto diet is a high-fat, low-carb diet that induces ketosis in the body. Ketosis is a metabolic state characterised by high levels of ketones in the blood. Ketones are natural chemicals produced by the body when it burns fat for energy instead of carbohydrates. The three main ketones produced by the body are hydroxybutyrate, acetoacetate, and acetone.

The keto diet has been associated with a range of side effects, one of which is body odour. Body odour can be caused by the excretion of ketones through urine, breath, and sweat. Acetone, in particular, has been linked to "keto breath", characterised by a fruity, nail polish remover-like smell.

Now, what about "keto crotch"? There have been reports from women on the keto diet about experiencing stronger vaginal odours. This has led to the term "keto crotch" to describe this phenomenon. While there is limited scientific evidence directly linking the keto diet to changes in vaginal odour, it is possible that the diet may impact vaginal acidity and the composition of microorganisms in the vagina, resulting in a stronger odour.

One theory suggests that the high-fat nature of the keto diet may lead to an increase in certain types of microorganisms in the vagina, which could contribute to a stronger odour. Additionally, the diet's impact on ketone production and excretion may also play a role in changing vaginal odour. However, more scientific studies are needed to confirm this link.

It is important to note that vaginal odour can be influenced by various factors, and an unusual odour could be a sign of an infection or other condition. If you are experiencing a very unusual vaginal odour, it is recommended to consult a doctor to rule out any potential medical issues.

While the keto diet may not be the direct cause of "keto crotch", the diet's impact on ketone production and excretion, as well as potential changes in vaginal acidity and microorganisms, could be contributing factors. More research is needed to fully understand the relationship between the keto diet and vaginal odour.
