Unpacking the Zero-Carb Cocktail
The low-carb profile of a rum and diet coke stems from its main ingredients. Distilled spirits, including unflavored rum, are processed to remove sugars and starches, resulting in a zero-carb beverage. Diet Coke uses artificial sweeteners to provide flavor without sugar or carbohydrates.
The Nutritional Breakdown
A typical rum and diet coke, made with a 1.5-ounce shot of rum and 6-8 ounces of Diet Coke, has the following breakdown:
- Rum: 1.5 oz (44ml) of plain rum has 0g carbohydrates, 0g sugar, and about 97 calories.
- Diet Coke: 8 oz contains 0g carbohydrates, 0g sugar, and 0 calories.
This mix is virtually carb and sugar-free, with calories coming from the alcohol in the rum, making it suitable for low-carb diets, including keto.
Potential Carb Traps to Avoid
While the classic version is low-carb, certain variations can add significant sugar.
- Flavored Rums: Some flavored rums contain added sugar, potentially adding 35-40 grams of carbs per serving. Always check labels or ask your bartender.
- Regular Cola: Using regular cola instead of Diet Coke adds a significant amount of sugar. A 12 oz can of regular Coca-Cola has about 39 grams of carbs.
- Juice Mixers: Premade sour mixes or fruit juices can add unwanted sugar, though a small amount of fresh lime is typically low-carb.
