Keto Breath: Causes And Cures For Bad Breath

The ketogenic diet is a popular choice for those looking to lose weight fast. However, one of its side effects is keto breath, which is caused by the body entering a state of ketosis and breaking down fats for energy instead of carbohydrates. This process creates chemicals called ketones, which are released through an individual's breath, resulting in an unpleasant odour that can be fruity, sweet, or similar to nail polish remover or ammonia. While keto breath is only temporary, there are several ways to reduce or mask it, including staying hydrated, eating more carbohydrates, and maintaining good oral hygiene.

Drink more water to flush out ketones and bacteria

Drinking more water is a great way to combat keto breath. Water is key to flushing out ketones and bacteria, which are the main causes of keto breath.

When the body is in ketosis, it converts fat cells into three types of ketones. One of these, acetone, is expelled from the body through urine, sweat, and breath. This is what gives your breath that distinctive "keto breath" smell. By drinking more water, you will produce more urine, which will help flush out the ketones.

Drinking water also helps to flush out bacteria in the mouth that could be causing bad breath. A dry mouth is one of the main causes of bad breath, as it allows bacteria to quickly grow and multiply. These bacteria are filled with volatile sulfur compounds (VSCs), or "bad breath molecules," which cause the unpleasant odor. Staying hydrated helps to prevent dry mouth and flush out these bacteria, improving your breath.

In addition to flushing out ketones and bacteria, drinking water can also help with weight loss goals. The keto diet is often used to lose weight fast, and staying hydrated can be a helpful tool in achieving those goals.

It is important to note that drinking water may not completely eliminate keto breath. However, it can help reduce the odor while your body adjusts to a low-carb diet.

Increase your carbohydrate intake to produce fewer ketones

If you're following a keto diet and are experiencing bad breath, you may want to consider increasing your carbohydrate intake to produce fewer ketones. This is because a ketogenic diet involves eating very few carbohydrates, which means your body will break down fats for energy, producing ketones. These ketones are released through your breath, giving off a distinct odour.

By increasing your carbohydrate intake, you can reduce the number of ketones produced and, therefore, reduce the odour. This doesn't mean you have to start eating lots of carbs again. A small adjustment to your carb intake can make an immediate difference in your breath. For example, if you're consuming 2,000 calories a day, you could try increasing your carbohydrate intake from 20 grams to 50 grams.

It's important to note that the number of carbohydrates you can eat without dropping out of ketosis will vary from person to person. You can use a ketone breath analyser to measure your ketone levels and determine whether you're still in ketosis after increasing your carb intake.

While increasing your carb intake may help with bad breath, it's not the only solution. Drinking more water can also help flush out the ketones, and improving your oral hygiene can help mask the odour.

Improve oral hygiene with tongue scraping and twice-daily brushing

Improving Oral Hygiene to Combat Keto Breath

Keto breath is a common side effect of the keto diet, but there are ways to reduce or eliminate it. One way to combat keto breath is to improve your oral hygiene.

Tongue Scraping

The keto diet can cause bad breath in two ways. Firstly, ketones produced by the body during ketosis can seep into your breath, giving it a distinct odour. Secondly, the foods eaten on the keto diet can contribute to bad breath. Volatile Sulphur Compounds (VSCs) or "bad breath molecules" are produced when protein is broken down, and these can linger at the back of the tongue.

Since 90% of bad breath originates from the tongue, it is important to keep it clean. While brushing your tongue with a toothbrush can help, the most effective way to clean your tongue is with a tongue scraper. Tongue scrapers are affordable and long-lasting, and they are the best way to ensure you are removing the bacteria that cause bad breath.

Twice-Daily Brushing

It is important to brush your teeth at least twice a day when on the keto diet. The minty odour of toothpaste can help to mask the smell of keto breath, and brushing your teeth will help to dislodge pieces of food that can cause additional bad breath as they break down in your mouth.

Brushing your teeth more frequently will not eliminate keto breath, but it can help to reduce the odour. It is also important to combine tooth-brushing with other oral hygiene practices, such as daily flossing, to ensure you are keeping your mouth as clean as possible.

Other Tips for Reducing Keto Breath

• Drink Plenty of Water: Drinking water helps to flush out ketones and improve your breath. It is also important to stay hydrated on the keto diet to avoid dehydration and digestion issues.
• Make Small Dietary Adjustments: If you are fed up with keto breath, you can try reducing your level of ketosis by slightly increasing your carb intake.
• Keep Your Mouth Moist: Dry mouth is a cause of bad breath as it allows bacteria to grow and multiply. Drinking water, running a humidifier at night, and sucking on sugar-free mints can all help to keep your mouth moist.
• Switch to an Alcohol-Free Mouthwash: Alcohol-based mouthwashes can dry out the mouth, so switching to an alcohol-free option can help to improve bad breath.
• Chew Sugar-Free Gum: Chewing gum can help to stimulate saliva production and freshen your breath. It can also help to stop the growth of bacteria in the mouth.
• Adjust Your Protein Intake: When the body metabolises protein, it produces ammonia, which can cause bad breath. Try to keep protein intake to about 30-35% of your daily calories.

Chew gum or suck on mints to mask the smell

If you're on a keto diet, you may experience "keto breath", a common side effect of eating high-fat, low-carb meals. It's a sign that your body is in ketosis, a metabolic state where your body burns fat for energy instead of carbohydrates. While this can be a good indication that your body is adjusting to the keto diet, the distinct metallic, fruity, or chemical smell of your breath can be unpleasant.

Chewing gum or sucking on mints can be an effective way to mask the smell of keto breath. However, it's important to choose sugar-free options, as regular gum and mints contain carbohydrates that can take you out of ketosis. Chewing gum or sucking on mints can increase saliva production, which helps to stop the growth of bacteria that cause bad breath. Additionally, the minty flavour can help to temporarily hide the smell of keto breath.

However, it's important to note that this is only a temporary solution, as it doesn't address the root cause of the issue. To truly get rid of keto breath, you may need to make adjustments to your diet, such as increasing your water intake, reducing your protein consumption, or slightly increasing your carbohydrate intake. Practicing good oral hygiene, such as brushing your teeth twice a day and flossing regularly, can also help reduce the odour.

Consume more fat and less protein to reduce ammonia and acetone

Keto breath is a common side effect of the keto diet, and it can be quite unpleasant. The good news is that there are ways to reduce it, and it's only temporary.

The keto diet is a high-fat, moderate-protein, low-carb diet. When your body is in ketosis, it starts burning fat for energy instead of carbohydrates, resulting in higher blood ketone levels. Ketones are natural chemicals that your body produces when you burn fat for energy. These include beta-hydroxybutyrate, acetoacetate, and acetone.

Acetone is one of the ketones responsible for keto breath, as it is also an ingredient in nail polish remover. The more acetone in your system, the more your breath will smell like nail polish remover. Another culprit of bad breath is ammonia, which is produced when your body breaks down protein.

To reduce ammonia and acetone, you can try consuming more fat and less protein. This may seem counterintuitive, as the keto diet is already high in fat. However, a 2014 study found that increasing dietary fat intake while reducing protein intake resulted in lower levels of ammonia and acetone.

By consuming more healthy fats like avocados, nuts, and olive oil, you can help reduce the amount of ammonia and acetone in your system. This, in turn, can help improve your breath while still staying true to the keto diet. It's important to note that making these dietary adjustments might mean you're slightly less in ketosis, but it could be a good solution to the keto breath issue.

In addition to modifying your fat and protein intake, there are other ways to manage keto breath, such as staying hydrated, practising good oral hygiene, and using sugar-free mints or gum. Remember, keto breath is only temporary, and your breath should return to normal within a few weeks as your body adjusts to the diet.
