Keto breath is a side effect of the ketogenic diet and other low-carb diets that can produce a distinct taste or odor in the mouth thats different from ordinary halitosis or bad breath. Some people describe keto breath as having a metallic taste, while others describe it as being fruity-smelling or having a strong odor thats similar to nail polish remover. The cause of keto breath is related to how metabolism works. Typically, your body will break down carbohydrates or glucose for energy first, and then fat. However, when youre on a low-carb diet, your body will break down fat for energy instead of carbohydrates, which causes the body to enter a metabolic state called ketosis. When the body is in a ketogenic state and in fat-burning mode, it can lead to weight loss and help regulate blood sugar, as well as help manage other health concerns. Yet, this is also where the keto bad breath comes in. As the body burns fat, the fatty acids are converted to ketones, including acetone, hydroxybutyrate, and acetoacetate, in the liver. Acetone is what gives your breath that distinctive "ketosis" smell.

There are a few things you can do to minimize keto breath, including:

• Use a ketone breath analyzer: This can help you determine the most carbs you can eat without being kicked out of ketosis. If you can add more carbs to your diet and eat less protein, this might be enough to keep your breath fresh.

• Lower protein intake: Too much protein can make your breath worse in the beginning stages of ketosis. Instead of focusing on protein sources for your fat intake, try vegetable fats from avocados, olive oil, and almonds.

• Keep brushing: Good oral hygiene is crucial for beating bad breath, whatever the cause. Keep brushing at least twice a day, floss once a day, and introduce a good mouthwash if you need some extra help.

• Stay hydrated: Drinking plenty of water can help flush out the ketones that cause keto breath.

• Chew gum or suck on mints: This can help mask the odor until keto breath goes away on its own.
