Keto breath is an unpleasant side effect that a person can develop when they begin following a ketogenic diet. A person can try to reduce keto breath by drinking more water or slightly increasing the number of carbohydrates they eat.



A ketogenic diet, or keto diet, involves a person eating very few carbohydrates. Instead, they get their calories from consuming fats and protein. People may describe the resulting breath smell as being fruity or sweet.



Some people claim that keto breath will disappear once the body adapts to being in ketosis. Researchers think it takes at least 21 days to reach this state.



By this point, a person's body is more effective at burning the ketones it produces. This means there are fewer ketones to breathe out, which implies keto breath should improve.

More than likely its not ketones you are smelling, but a shift in anaerobic bacteria in the mouth. Their metabolism produces some foul smelling amines with names like cadaverine and putrescine.

Yes it's acetone, this is what ketone breath analyzers measure.

Yes indeed and it can be quite horrific smelling at times. Nothing worse than a pretty girl with nasty breath

It's often times chalked up to acetone as this an expected volatile that is produced during ketosis, but the halitosis you describe is not from acetone. Concentrated acetone doesn't smell like bad breath. Also, all the literature describes ketones as "fruity".

It's the shift in microbial ecology in the mouth from lack of carbohydrates. Best bet is mouthwashes, try some with zinc in it, which binds sulfurous byproducts and frequent brushing and flossing.
