CUT OUT THE CRASH DIET
Certain types of weight-loss regimes are known to cause halitosis, especially those that involve extreme limitation of carbohydrates. Those who embark on juice fasts or intermittent fasting are also at increased risk of bad breath. These regimes are based on triggering a metabolic state known as ketosis, when the body begins to burn its own fat stores. This prompts the release of ketones into the bloodstream which in turn can cause an acetone, or an unpleasant ammonia-type smell on the breath.
