Hi all,

I am so worried about the bad breath which apparantly comes with getting into Ketosis.

Please can someone shed some light in what this smells like? and how long does this last? Is it the whole of your weight loss journey.

I am so worried

I didn't really notice it. I've heard that it should last a few weeks. I drink a lot of water and that means the ketones can escape through my urine rather than through my breath so that would be worth a try. Also you can use mouth spray but make sure that it's sugar free and doesn't contain citric acid.

I don't notice it either, drink plenty water and you should be fine.
