Keto Diet And Stinky Gas: What's The Link?

The ketogenic diet, commonly known as the keto diet, is a high-fat, low-carbohydrate diet that has gained popularity for its weight-loss benefits. However, it has also been associated with some unpleasant side effects, including bad breath, body odour, and gastrointestinal issues such as gas and bloating. Some people who follow the keto diet have reported experiencing smelly gas, which has been attributed to various factors, including changes in food consumption, decreased fibre intake, dehydration, and increased consumption of sugar alcohols found in low-carbohydrate foods. While the keto diet can lead to weight loss, it's important to be aware of these potential side effects and their possible causes.

Keto and body odour

The ketogenic (keto) diet is a high-fat, low-carbohydrate diet that has become increasingly popular. While it has shown significant health benefits for many people, it can also cause some adverse side effects, including body odour. Here are some things to know about keto and body odour:

Keto Breath

One of the most common side effects of the keto diet is "keto breath," which can manifest as a fruity or chemical smell, similar to nail polish remover. This is caused by the production of ketones, specifically acetone, during ketosis. While it can be unpleasant, there are several ways to minimise keto breath, including:

• Increasing water intake to stay hydrated and flush out ketones through urination.
• Lowering protein intake as the breakdown of protein produces ammonia, which can contribute to bad breath.
• Practising good oral hygiene, such as brushing teeth twice a day and flossing daily, to reduce bacteria in the mouth.
• Using sugar-free mints or gum to temporarily mask the odour.
• Increasing carbohydrate intake slightly, as this may help reduce ketone production.

Body Odour

In addition to keto breath, the keto diet may also impact other areas of body odour, such as underarm odour. This is believed to be related to changes in the body's pH levels and the growth of "bad" bacteria. Here are some tips to manage body odour while on the keto diet:

• Maintain proper hydration by drinking enough water.
• Incorporate plant-based foods into your diet, such as non-starchy vegetables and certain fruits, to ensure adequate fibre intake.
• Be mindful of sugar alcohol consumption, as these can be linked to gastrointestinal issues, including flatulence.
• Consider taking probiotics to support digestive health and reduce potential gas and bloating.
• Monitor your protein intake, as excessive protein can impact body odour and may not be necessary for ketosis.

While the keto diet can cause some changes in body odour, these side effects are typically temporary and can be managed with adjustments to your diet and lifestyle. It is important to listen to your body and make any necessary changes to ensure your comfort and well-being.

Keto crotch

The "keto crotch" is a term that has been used to describe an intense odour in the vaginal region as a result of a low-carb ketogenic diet. While there is currently no clinical research to support this claim, many women have taken to Reddit to share their experiences.

The ketogenic diet involves lowering your carbohydrate intake and increasing your consumption of healthy fats and proteins. When your body is in ketosis, it breaks down fat for fuel instead of carbohydrates, producing ketones, which are natural chemicals. These chemicals are usually harmless and are released from the body through exhalation and urination. However, an excess of these chemicals can lead to an increase in odour from the body, including the vaginal region.

Obstetrician and gynaecologist, Dr Sherry A. Ross, explains that altering the number of fats and carbohydrates in a woman's diet can impact the odour emitted from the vagina. She states that pungent foods and spices can create especially intense smells in the genital area. Lisa De Fazio, a registered dietitian nutritionist, agrees that the keto diet may change the vaginal pH, leading to an odour. De Fazio also highlights that a pH imbalance can result in the growth of bad bacteria, which can cause irritation, odour, and infections such as bacterial vaginosis.

To address "keto crotch", it is recommended to ensure proper hydration by drinking enough water. Additionally, it may be beneficial to review your diet and ensure adequate fibre intake, as low-carb diets can sometimes lack fibre, leading to gastrointestinal discomfort. It is also important to be mindful of sugar alcohol consumption, as these can be linked to irritable bowel syndrome (IBS) and flatulence.

While the ketogenic diet may lead to "keto crotch" for some women, it is important to note that individual experiences may vary. Some women have reported a decrease in odour or a complete absence of odour while on the keto diet.

Keto breath

The ketogenic diet (or keto diet) is a high-fat, moderate-protein, low-carb diet designed to help you achieve ketosis. Ketosis is a natural metabolic state that occurs when your body doesn't receive enough carbs for energy and starts burning fat for fuel.

One of the three types of ketones produced by the body when it is fuelled by fat is acetone, which is also found in nail polish remover. Acetone is excreted through breath, causing a fruity or chemical smell, which is known as "keto breath".

• Drink more water to increase urination and flush out ketones.
• Lower your protein intake as the breakdown of protein produces ammonia, which can cause bad breath.
• Practice good oral hygiene by brushing your teeth twice a day and flossing daily.
• Chew sugar-free gum or suck on sugar-free mints to stimulate saliva production and freshen your breath.
• Increase your carbohydrate intake by a small amount to reduce the level of ketones produced by your body.

Keto flatulence

Flatulence is a common side effect of the keto diet, with many people reporting an increase in gas when they first start out. This is often due to the fact that the keto diet is low in fibre, and that those on the diet are often not properly hydrated.

There are several reasons why flatulence may increase when starting the keto diet:

• Lack of fibre: Fibre is a type of carbohydrate, and because the keto diet restricts your carbohydrate intake, it can be difficult to maintain proper amounts of fibre in your diet. Fibre is essential for keeping your digestive system healthy and regular, and not consuming enough can lead to constipation and gas.
• Dehydration: The keto diet can have a diuretic effect, causing you to lose water and become dehydrated. This can leave you feeling bloated and constipated, which can contribute to flatulence.
• Excess protein: Eating too much protein can cause bad breath and flatulence. As your body breaks down protein, it produces ammonia, which has a strong odour and can be eliminated through exhalation and urination.
• Sugar alcohols: Sugar alcohols are often used as a replacement for sugar in low-carbohydrate foods. They are not fully absorbed by the body and have been linked to irritable bowel syndrome (IBS) and flatulence.
• Food intolerances: The keto diet may involve introducing new foods into your diet or eating more of certain foods, such as eggs or dairy, which can cause flatulence if you have an intolerance.

How to reduce flatulence on keto:

• Increase your fibre intake: Aim to include more high-fibre, low-carbohydrate foods in your diet, such as non-starchy vegetables (e.g. spinach, broccoli, cauliflower), berries, and avocados.
• Stay hydrated: Drink plenty of water to counteract the diuretic effect of the keto diet and help relieve bloating and constipation.
• Reduce your protein intake: If you're consuming too much protein, try replacing some of it with healthy fats like avocados, nuts, and olive oil.
• Avoid sugar alcohols: Check food labels and avoid ingredients that end in "-ol", which indicates a sugar alcohol.
• Identify food intolerances: Keep a food diary to help identify any foods that may be causing flatulence. You can also try an elimination diet, where you remove one food at a time to see if your symptoms improve.

Keto and gut health

The ketogenic diet is a high-fat, low-carbohydrate, and moderate-protein diet. It has been promoted by celebrities such as Gwyneth Paltrow and Jenna Jameson, who claim that it helped them lose weight. However, some people have reported experiencing negative side effects, such as bad body odour, after following the keto diet.

Keto Breath

One of the most common side effects of the keto diet is bad breath, often described as "dragon breath" or "keto breath." This is caused by the production of ketones, natural chemicals that the body produces when it burns fat for energy. One of these ketones is acetone, which is also found in nail polish remover and can give the breath a fruity or chemical smell. Keto breath usually goes away on its own as the body adjusts to the diet, but it can be mitigated by drinking more water, lowering protein intake, improving oral hygiene, and using sugar-free mints or gum.

Keto Crotch

Some women have reported experiencing an unusual odour in their vaginal area, dubbed "keto crotch," after following the keto diet. This may be due to changes in the vaginal pH caused by the high-fat, low-carb diet, leading to an imbalance of bacteria and potentially causing irritation, odour, and infections. However, there is limited clinical research on this topic.

The keto diet can also affect gut health. Some people experience gastrointestinal discomfort, such as gas and bloating, when starting the keto diet. This is often due to a lack of fiber, as fiber is a type of carbohydrate that is restricted on the keto diet. Additionally, the keto diet may cause dehydration, which can further contribute to bloating and constipation. It is important for people on the keto diet to ensure adequate fiber and water intake to maintain gut health.

Some people also experience increased gas on the keto diet due to the consumption of certain foods, such as sugar alcohols, which are often used as sweeteners in low-carb products. Sugar alcohols can cause irritable bowel syndrome (IBS) and flatulence. Therefore, it is recommended to limit the consumption of packaged low-carb foods and focus on whole foods, such as non-starchy vegetables and certain fruits, which are high in fiber and suitable for the keto diet.

In conclusion, while the keto diet may offer some health benefits, it is important to be aware of potential side effects, such as bad breath and gastrointestinal issues. To maintain gut health while on the keto diet, it is crucial to stay hydrated, consume enough fiber, and prioritize whole foods over highly processed low-carb options.
