Keto Breath and Low-Carb Diet

What is keto breath? There are many causes of keto bad breath. However, low-carb diets have two main culprits: ketosis (a metabolic state achieved with a low-carb diet) and protein metabolism.

How Long Does Keto Breath Last

One of the main sources of energy in the body is glucose. Glucose is formed when the digestive tract breaks down carbohydrates from complex sugars to simple glucose molecules. What does keto breath taste like? When you reduce your carbohydrate intake, your body must look for alternative sources of fuel (namely fat) for energy – a metabolic state known as ketones.

When the body breaks down fatty acids, it creates a byproduct known as ketones. Common ketone bodies come in three forms: acetoacetate, beta-hydroxybutyrate, and acetone. These ketone bodies are regularly removed from your body when you urinate and exhale.

If you are on a low-carb diet, your body relies more on fatty acids for energy because you eat fewer carbs. As your body uses more fat, more ketones are released as a metabolic by-product.

Excessive buildup of ketones in your body can contribute to bad breath keto. 2 However, the ketones you keto taste in mouth out have very distinctive odors, most of which do not resemble bad breath (bad breath).

Protein metabolism

Diet changes can also cause changes in your keto bad taste in mouth. On a low-carb, the sudden switch from carbohydrates to protein changes the way food is metabolized. When protein breaks down in the body, ammonia is formed. A sudden spike in dietary protein will only amplify this effect, increasing the amount of ammonia in both your stomach gases and urine.

Because ammonia requires a lot of water to flush out, insufficient hydration can worsen bad breath as ammonia builds up quickly in the body.

Symptoms When Does Keto Breath Go Away

Keto breathing varies from person to person, but generally it is not the same as keto and bad breath. Bad ketones breath that most of us experience from time to time is caused by bacteria in the mouth. When these bacteria begin to break down the food we eat, they create volatile sulfur compounds (VSCs) .4 These compounds usually have a sulfurous odor (similar to rotten eggs).

In keto breathing, odor characteristics change depending on which by-products of protein and fat metabolism are formed. For example:

  • Acetoacetate and beta-hydroxybutyrate can give your breath a sweet and fruity smell. Some people describe a smell similar to that of rotting apples.
  • Acetone creates a more resinous odor when inhaled (like nail polish).
  • Excessive protein metabolism can cause ammonia odor in both breath and urine.
  • Treatment.
  • In most cases, keto breathing goes away on its own, although it can take several weeks to a month. If you are on a low-carb diet, here are some ways to alleviate the symptoms of bad breath on keto while your metabolism improves.

Drink plenty of water. Aim to drink at least eight 8-ounce glasses of water a day. This not only helps to flush excess ketones and VSCs from the body, but it also aids digestion and prevents constipation.

How to Get Rid of Keto Breath?

Rebalance your protein intake. While it’s a matter of trial and error, changing protein sources – say, from chicken to meat or from meat to fish – can sometimes affect which ketone bodies are produced (mainly due to the types of fatty acids starting to break down).

Increase your fat intake. Research shows that increasing fat while reducing protein intake can help minimize acetone and ammonia emissions.
Don’t overload carbohydrates. Don’t overdo it and cut out more carbs than you need. For example, the South Beach Diet is not as strict on carbohydrates as the Atkins Diet. However, none of them are committed to zero carbs. If you suspect that you have overdone your carbohydrate cut, try increasing your healthy carbohydrate intake within the prescribed limit.

Practice good oral hygiene. Brush your teeth, floss and rinse with an antibacterial mouthwash. Regular scraping of the tongue can also help.
Disguise the breath. Try natural breath fresheners (such as mint, parsley, cloves, cinnamon, or fennel seeds) or breath capsules made with parsley or chlorophyll oil.
