“What can I drink?” is one of the most common questions I got when I was a slow carb diet coach. The good news is there are cocktails you can enjoy, as long as you choose compliant ingredients.
This blackberry mojito uses a blackberry mint shrub syrup instead of sugar, which adds complex flavor without a load of carbs. The result is a refreshing cocktail at barely over 100 calories.
The key to slow-carb cocktails is knowing your ingredients. Distilled spirits have no carbs. The problem is usually the mixers. Skip the tonic water, sweet and sour mix, and bloody mary mix. They’re loaded with sugar.

What to know about alcohol and a slow carb lifestyle?
These are the five tips that I consider most important when incorporating alcohol into a low carb lifestyle:
- Metabolism priority: Alcohol is processed in the liver and it is metabolized first, before anything else. It will temporarily disrupt or pause fat burning if you are in a state of ketosis. If you are on a keto diet, just know that the disruption of ketosis is temporary, unlike the longer term impact of eating sugar and carbs.
- Faster effects: People on a low carb or keto diet will feel the effects of alcohol much quicker than those on a Standard American Diet (SAD).
- Faster recovery: You’ll also recover from alcohol’s effects more quickly.
- Worse hangovers: Hangovers are significantly worse on low-carb diets. Be careful and moderate your intake.
- Electrolytes help: Replenishing electrolytes after a night out before bed can help tremendously with avoiding a hangover the next day. This video will walk you through a quick and easy morning drink called Ketorade that is great for replenishment of electrolytes. Ketorade is also an excellent morning drink for starting any day with energy.
What Alcohol is Acceptable vs What to Avoid?
Here are 4 tips to be aware of when choosing your drinks:
- Avoid beer: Beer is quite high in carbs and gluten and even “low carb beer” isn’t really compliant. This is probably the worst form of alcohol you can have if your goal is to lose fat, especially belly fat. They don’t call it a beer-belly for nothing!
- Choose distilled spirits (unflavored): Vodka, gin, rum, bourbon, scotch (unflavored) have no carbs. They temporarily disrupt ketosis but don’t add to your carb count.
- Watch out for mixers: Tonic water, sweet and sour mix, and bloody mary mix are heavy with sugar and carbs. Opt for your favorite spirit with some club soda and a few squeezes of lime for the best low carb drink.
- Dry wine in moderation: Dry wine is not too bad, but it does have carbs, so take it easy on the amount.
Ingredients for Slow Carb Blackberry Mojito
- Mint: Essential for any mojito. Use fresh.
- Blackberries: Fresh or frozen both work. Frozen berries are fine for muddling.
- Lime: Another essential. Fresh is best. Bottled works in a pinch. Lemon doesn’t substitute well.
- Stevia: Optional, for extra sweetness without carbs.
- White rum: Any white rum works.
- Sparkling water: To top it off. No calories, no carbs.
