Keto Diet: Bad Breath And How To Get Rid Of It

The ketogenic diet is a popular, effective way to lose weight and improve health. However, one of its common side effects is keto breath, which is caused by the presence of acetone, a ketone produced by the liver from fat breakdown. This gives the breath a fruity or nail polish remover-like smell, which can be embarrassing and uncomfortable in social situations. The good news is that keto breath is temporary and will go away as your body adjusts to using fat for energy, which may take a few days to a few weeks. In the meantime, there are several remedies you can try to reduce or mask the odour, including increasing your water intake, lowering your protein intake, and practising good oral hygiene.

Keto breath is caused by ketones in the breath

The ketogenic diet is a high-fat, moderate-protein, and low-carb diet. When an individual follows a keto diet, their body enters a metabolic state called ketosis, where it burns fat for energy instead of carbohydrates. During ketosis, the body breaks down fat into fatty acids, which are then converted into ketones. These ketones are natural chemicals that the body produces when it burns fat for energy.

Keto breath is a common side effect of ketosis. It is caused by the presence of ketones in the breath, specifically acetone, a type of ketone that is also found in nail polish remover. Acetone exiting the body through the breath gives it a distinct odour, which some people describe as fruity, sweet, or similar to nail polish remover.

The good news is that keto breath is only temporary. It typically lasts for a few days or weeks, while the body adjusts to using fat for energy instead of carbohydrates. During this adjustment period, there are several remedies that can help reduce keto breath, including increasing water intake, lowering protein intake, and practising good oral hygiene.

Keto breath indicates ketosis

The ketogenic, or keto, diet is a popular, effective way to lose weight and improve your health. It involves eating very few carbohydrates and getting your calories from consuming fats and proteins instead.

When you restrict your carbohydrate intake, your body produces glucose. When this is not enough, it produces ketones that it burns for energy. This state is called ketosis.

One of the signs that your body has entered ketosis is a change in the way your breath smells. This is known as "keto breath".

Keto breath is different from typical "bad breath". It has a very distinct smell and taste. Some people describe it as fruity or sweet, like rotting apples, while others say it has a metallic taste or a chemical smell, similar to nail polish remover.

Keto breath occurs when your body breaks down fat for energy. The broken-down fat, now fatty acids, are converted into ketones, which are expelled from the body through breath and urination. The specific culprit behind keto breath is acetone, a type of ketone that exits the body in your urine and breath.

While this breath may be off-putting, it can be a positive sign for your diet as it indicates that you have entered ketosis, which is the goal of the keto diet.

How to Get Rid of Keto Breath

Keto breath usually appears in the first week or two of starting the keto diet, and it is not permanent. Your body will eventually become accustomed to its new carb intake levels and your breath will return to normal. In the meantime, there are several things you can try to minimise keto breath:

• Drink more water – This helps to flush out ketones from your body and improves your breath.
• Increase your carbohydrate intake – You can still achieve ketosis while eating more carbohydrates. A ketone breath analyser can help you determine the right amount of carbs to stay in ketosis.
• Lower your protein intake – Eating too much protein can worsen keto breath, especially in the beginning stages of ketosis, as your body breaks down protein into ammonia, another byproduct of metabolism that is eliminated through urination and exhalation.
• Practice good oral hygiene – Brushing your teeth twice a day and flossing daily may not completely eliminate keto breath, but it can help reduce the odour.
• Mask the odour with mints and gum – Choose sugar-free options that won't interfere with your low-carb goals.

Keto breath is temporary

Keto breath is a common side effect of the keto diet. It is caused by the presence of acetone, a ketone produced by the liver from fat breakdown. While it can be embarrassing, especially in social situations, it is a sign that the diet is working and your body is burning fat for energy.

Keto breath usually starts within a few days to a week of beginning the keto diet. It is only temporary and typically lasts a few weeks, while your body adjusts to its new carb intake levels and gets used to burning fat for energy.

How to Get Rid of Keto Breath

Although keto breath will go away on its own, there are some things you can do to minimise it in the meantime:

• Drink more water– this helps to flush out ketones through urination.
• Eat more carbs– increasing your carb intake by just 5 grams daily can make a difference.
• Chew gum or suck on mints– this helps to mask the smell of keto breath, but make sure to choose sugar-free options.
• Lower your protein intake– too much protein can make your breath worse, as it produces ammonia, which smells unpleasant.
• Practice good oral hygiene– brushing your teeth twice a day and flossing once a day can help to reduce the odour.

When to Seek Help

While keto breath is generally harmless, if you are experiencing other conditions that are causing bad breath, you should seek advice from a medical professional. Additionally, if you are not on the keto diet, keto breath can be a sign of diabetes complications from diabetic ketoacidosis (DKA).

Drinking water can help reduce keto breath

Keto breath is an unfortunate side effect of the keto diet. It is caused by the presence of ketones in the breath, which can give it a fruity or chemical smell, or a metallic taste. While it is a sign that the diet is working, it can be embarrassing and unpleasant.

Drinking plenty of water can help to reduce keto breath. This is because ketones are flushed out of the body through urination. Staying hydrated means you will urinate more, helping to expel ketones from the body. Drinking water may also help to flush out bacteria in the mouth, which can be a cause of bad breath.

It is important to note that chugging water all the time can lead to overhydration, which can cause low sodium levels and result in headaches and loss of energy. So, while drinking water can help to reduce keto breath, it is important to stay properly hydrated and not overdo it.

In addition to drinking water, there are other ways to reduce keto breath, including lowering protein intake, increasing carbohydrate intake, practising good oral hygiene, and using mints or gum. Keto breath should also go away on its own as your body adjusts to the diet, which may take a few weeks.

Maintaining oral hygiene is important to reduce keto breath

Keto breath is caused by the presence of ketones in the saliva, which occurs when the body enters ketosis and starts burning fat for energy. This process creates three types of ketones: acetoacetate, beta-hydroxybutyrate, and acetone. Acetone is the ketone responsible for the distinctive fruity or nail polish remover-like odour of keto breath.

Practicing good oral hygiene can help to reduce the odour of keto breath. This includes brushing teeth at least twice a day, daily flossing, and cleaning the tongue. Tongue cleaning is especially important as it removes bacteria that can cause bad breath. In addition to regular brushing and flossing, using a mouthwash, tongue scraper, and interdental brushes or water flossers can further improve oral hygiene.

While maintaining oral hygiene is crucial, it is important to note that it will not completely eliminate keto breath. This is because the odour comes from the lungs, and oral hygiene practices only mask the smell rather than fix the underlying cause. However, combining good oral hygiene with other strategies can help to minimise keto breath.

One way to reduce keto breath is to lower protein intake. Since the keto diet is already low in carbohydrates, focusing on vegetable fats like avocados, olive oil, and almonds instead of high-protein foods can help improve breath odour. Additionally, staying hydrated by drinking plenty of water can help flush out ketones and bacteria that contribute to bad breath. Chewing sugar-free gum or sucking on sugar-free mints can also help to stimulate saliva production and mask the odour of keto breath.

In summary, maintaining oral hygiene and combining it with other strategies like reducing protein intake, staying hydrated, and using sugar-free gum or mints can help to minimise keto breath while your body adjusts to the diet.
