When your body primarily burns fat as fuel rather than glucose, it generates ketones, the by-products of fat breakdown that are released in your breath and your urine. While this can be annoying, the good news is that you’re burning stored body fat. The more ketones you release, the more fat you’ve burned.

Drinking plenty of water helps dilute the concentration of ketones. Parsley is a natural breath freshener lasts only a few weeks.
