Ketogenic, or keto diets, are very popular but some followers have reported suffering from bad breath.
A keto diet involves eating plenty of meat, fish, eggs and natural fats which have been blamed for bad breath. As body fat is burned off, ketones are produced in the liver which are released into your urine and, sometimes, into your breath. The odour has been described as smelling like:

– Acetone
– Ammonia
