5 liquids that technically won’t break a fast

Science says so.

Technically, fasting is going without any food for a period of time.

Meanwhile, intermittently fasting to put the body in ketosis — or relying on ketones instead of glucose for energy — is associated with some benefits.

One way to fast safely is with the help of liquids low in calories and carbs that won’t break that metabolic switch.

These include...

Broths (bone or vegetable) can help replenish nutrients and minerals during a fasting period.

In one study, drinking tea while fasting instead of with a meal improved markers for cardiovascular health.

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.
