Is Rum Keto?

Yes, rum is surprisingly keto-friendly! Rum as well as other alcohols such as whiskey and vodka have zero carbs. And you can use white rum as well in this low-carb cocktail recipe. So, if you are on a keto diet, moderate amounts of rum are perfectly acceptable. Just make sure to use a sugar replacement when you are mixing the alcohol to make cocktails.

Other Summer Keto Cocktails

If you don’t particularly love limes, rum, or just mojitos in general, that’s ok! You can change it up with some other summer keto cocktails such as a keto piña colada, a keto strawberry daiquiri, or a keto margarita.

For a coconut flavored cocktail, try the keto piña colada recipe which includes rum, coconut milk, pina colada extra, and monkfruit sweetener.

Keto Mojito: FAQS

Can I make this mojito without alcohol?

Absolutely! Just skip the light rum and you'll have a delicious keto mocktail mojito that's just as refreshing.

What can I substitute for the sugar-free brown sugar sweetener?

If you don’t have sugar-free brown sugar sweetener, you can use another keto-friendly sweetener like erythritol or monk fruit sweetener, adjusting the amount to taste.

How should I store leftover mojito?

It's best to enjoy this mojito fresh, but if you have leftovers, store it in an airtight container in the fridge for up to 24 hours. Just note that the mint may lose its freshness.

Yes! This keto mojito is sugar-free and low in carbs, making it a great choice for anyone following a keto diet.
