Keto is an increasingly popular low-carb, high-fat diet restricts the intake of carbs, which puts your body into a state of ketosis — where burning fat instead of glucose causes you to lose weight.
While many supporters have raved about keto’s benefits, there's one thing that isn't always mentioned — that bad breath is one of its potential side effects! Some describe keto breath as a smell that's sweet, fruity or reminiscent of nail polish remover. This less-than-alluring side effect is caused by the chemicals your body creates during ketosis, which are released when you exhale.
