If a jump-start to your metabolism is what you’re after, coffee can add an extra boost (though some scientists debate this). It can, however, provide some small amounts of protein.

Caffeine can also increase fat oxidation, along with a host of other health benefits.

When taken in small doses, vinegar should not interrupt ketosis because it has less than 1 g of carbs per tablespoon.

Vinegar increases a feeling of fullness during a fast and may have other health benefits.


Sparkling water counts.



Water is the liquid that needs no introduction. It’s key to stay hydrated, even on a strict fast.
