Keto Breath: No Carbs, Bad Breath?

The ketogenic diet is a high-fat, moderate-protein, low-carb diet designed to help you lose weight faster by achieving ketosis. However, an unwanted side effect of this process is keto breath, which is caused by the presence of ketones in the breath, specifically acetone, which is also found in nail polish remover. Keto breath usually occurs within the first few days or weeks of starting the diet and can last for many weeks or a few months. It is characterised by a fruity or chemical smell, or a metallic taste in the mouth.

Keto breath is caused by ketosis

Keto breath is an unfortunate side effect of the body entering ketosis, which happens when you follow a low-carb, high-fat diet. Ketosis is a metabolic state that occurs when your body doesn't have enough carbohydrates to burn for energy, so it starts burning fat instead. This process creates ketones, which are natural chemicals that your body gets rid of through breath and urine. One of these ketones is acetone, which is found in nail polish remover, and this is what gives your breath a fruity or chemical smell.

Keto breath is not a permanent problem. It usually starts within a few days to a week of beginning a low-carb diet and lasts for a few weeks or a couple of months. However, it will return if you go back to a low-carb diet after stopping. While it's happening, there are several things you can do to reduce keto breath. Firstly, drinking plenty of water will help to flush out the ketones through urination. You can also try reducing your protein intake, as the breakdown of protein produces ammonia, which can also cause bad breath. Eating more carbs will also reduce keto breath, and you can use a ketone breath analyser to make sure you're still in ketosis. Maintaining good oral hygiene is also important for keeping your breath fresh.

Ketosis is when your body breaks down fat for energy

Ketosis is a metabolic state that occurs when your body breaks down fat for energy instead of glucose. Typically, your body uses blood sugar (glucose) as its key energy source. This glucose is derived from dietary carbohydrates, such as starches and sugars. When you follow a low-carb diet, your body has to use up fat stores for energy, as you aren't introducing any fast-metabolising carbs.

When your body breaks down fat, it produces a compound called ketones, or ketone bodies, which become your body and brain's main source of energy. Ketones are natural chemicals that your body produces when you burn fat for energy. They include beta-hydroxybutyrate, acetoacetate, and acetone.

The fat your body uses to create ketones may come from your diet or your body's fat stores. Your liver produces a small amount of ketones on its own, but when your glucose level decreases, your insulin level decreases too. This causes your liver to ramp up ketone production to ensure it can provide enough energy for your brain. Therefore, your blood has high levels of ketones during ketosis.

Ketones are usually harmless and are released from the body through exhalation and urination. However, high levels of ketones can be dangerous, leading to a condition called ketoacidosis.

Ketosis can be induced by following the ketogenic, or keto, diet. This is a high-fat, moderate-protein, and low-carb diet designed to help you achieve ketosis. The standard keto diet consists of 70% to 80% fats, 10% to 20% proteins, and 5% to 10% carbohydrates.

Ketones are released through breath and urine

Ketones are natural chemicals that your body produces when you burn fat for energy. These include beta-hydroxybutyrate, acetoacetate, and acetone. Ketones are usually harmless and are released from the body through exhalation and urination.

Acetone is an ingredient in some nail polishes, so your breath may smell like nail polish remover, which can be an indicator of ketosis. The fruity smell of acetone is also an indicator of ketosis.

The body gets rid of ketones through urine, so drinking more water can help to flush out ketones. However, it is important to avoid overhydration, as this can throw off your electrolyte levels and result in low sodium levels, leading to headaches and loss of energy.

Ketones can also be released through the breath. This can result in "keto breath", which is an unwanted side effect of ketosis and can be embarrassing, especially in social situations. Keto breath usually appears in the first week or two of starting a keto diet and is temporary. It should go away after a few weeks, as the body adjusts to a lower carb intake.

To reduce keto breath, you can try lowering your protein intake and increasing your consumption of healthy fats, such as avocados, nuts, and olive oil. Drinking more water and practising good oral hygiene can also help to minimise the odour.

Keto breath smells fruity or like nail polish remover

Keto Breath: The Fruity or Nail Polish Remover Scent

Keto breath is an infamous side effect of the keto diet, a high-fat, low-carb eating plan. It is characterised by a distinct fruity or chemical odour, reminiscent of nail polish remover. This unique scent is caused by the presence of ketones, specifically acetone, in the breath. While it may be socially awkward, keto breath is a positive sign that your body has entered ketosis, the desired state of the keto diet.

The keto diet restricts carbohydrates, forcing the body to use fat stores for energy. This process, known as ketosis, involves breaking down fat into fatty acids, which are then converted into ketones. These ketones, including beta-hydroxybutyrate, acetoacetate, and acetone, are released from the body through exhalation and urination. Acetone, a key ingredient in nail polish remover, is the culprit behind the distinctive scent of keto breath.

Keto breath typically appears within the first week or two of starting the keto diet, as your body adjusts to the new carb intake levels. It is a temporary issue, lasting only until your body becomes accustomed to the low-carb intake, usually within a couple of weeks.

Managing Keto Breath

While it is challenging to prevent keto breath entirely, there are several strategies to minimise its impact:

• Increase water intake to flush out ketones through urination.
• Lower protein intake as excessive protein can worsen breath odour.
• Practice good oral hygiene, including brushing, flossing, and mouthwash.
• Mask odour with sugar-free mints or gum.
• Slightly increase carb intake to reduce ketone levels, while still maintaining ketosis.

Keto breath is temporary

Keto breath is an unfortunate side effect of the keto diet, which can be embarrassing, particularly in social situations. The good news is that it is only temporary and usually lasts just a few weeks. It is also a sign that the keto diet is working, as it indicates that your body is in ketosis, burning fat for energy.

Keto breath is the result of your body going into ketosis, which is the goal of the keto diet. When you eat a low-carb diet, your body has to use fat stores for energy, as it is not getting its usual source of fast-metabolising carbs. Ketosis is when your body is breaking down fat for energy, converting fatty acids into ketones. These ketones are expelled from the body through breath and urination.

Keto breath is often described as smelling like acetone nail polish remover, or having a fruity or metallic odour. It can also cause a metallic taste in the mouth.

How to Get Rid of Keto Breath

Although keto breath is temporary, there are some things you can do to reduce it in the meantime. Firstly, you can try drinking more water. As ketones are also removed from the body through urination, staying hydrated will help to flush out the ketones. You can also try eating less protein, as when the body metabolises protein, it produces ammonia, which can cause bad breath. Try eating more vegetable fats from avocados, olive oil and almonds, instead of protein sources for your fat intake.

You can also try eating more carbs, increasing your intake by about 5 grams per day, which will lower the level of stinky ketones your body produces. You can also try chewing sugar-free gum or mints, and of course, maintaining good oral hygiene by brushing your teeth and flossing regularly.
