Alcohol contains approximately 7 calories per gram, which is nearly as dense as fat. For weight-conscious drinkers, selecting the right spirit and mixer can significantly impact overall caloric intake. While many people believe that certain spirits have inherently fewer calories than others, the primary determinant for a straight shot's calorie count is its alcohol content, or proof.
The Lowest-Calorie Spirits: A Closer Look
When considering standard 80-proof spirits, the differences in calorie count per 1.5-ounce shot are minimal. Vodka, tequila, gin, and light rum all land in a very similar, low-calorie range. Higher proof versions of these spirits will naturally contain more calories.
Vodka
Vodka is the quintessential low-calorie spirit. Distilled to be a neutral spirit, it contains no sugars, carbs, or fat. A standard 1.5-ounce shot of 80-proof vodka contains around 96 calories. Its neutral flavor also makes it an excellent base for low-calorie cocktails when paired with diet-friendly mixers.
Tequila
Like vodka, pure agave tequila is another excellent low-calorie choice. A 1.5-ounce shot of 80-proof tequila blanco has approximately 96-97 calories and zero carbs. Those on keto or low-carb diets often favor tequila for this reason. It's important to choose 100% agave tequila, as cheaper brands may contain added sugars.
Gin
Distilled with juniper berries and other botanicals, gin offers a more complex flavor profile but maintains a low-calorie count. A 1.5-ounce shot of standard 80-proof gin contains roughly 97 calories, putting it on par with vodka and tequila. Again, the key is to avoid sugary tonics and mixers that add significant calories.
Whiskey
Whiskey, a spirit distilled from fermented grain mash, is also a low-calorie option when consumed neat. A 1.5-ounce shot of 80-proof whiskey is generally around 97 calories. Note that aged whiskeys and flavored varieties can sometimes contain trace amounts of sugar, which slightly alters the final calorie count, but not drastically.
Why Mixers Matter So Much
While the base spirits are all relatively low in calories, the choice of mixer can dramatically increase a drink's calorie content. For instance, a vodka tonic with regular tonic water can add an extra 100 calories or more to a drink. This is why cocktails often have hundreds of calories, despite being made with a low-calorie spirit. To keep your drinks light, consider the following low-calorie mixer options:
- Diet soda or sugar-free tonic water
- Soda water or sparkling water
- Freshly squeezed lime or lemon juice
- A splash of cranberry or orange juice
- Muddled mint or other fresh herbs
Calorie Comparison: Spirits vs. Mixers
This table illustrates how calories can change based on your choice of spirit and mixer, assuming a 1.5 oz (44 ml) shot.
| Beverage | Serving Size | Calories | Notes |
|---|---|---|---|
| Vodka (80 proof) | 1.5 oz shot | ~96 kcal | Zero carbs, zero sugar |
| Tequila (80 proof) | 1.5 oz shot | ~96 kcal | Choose 100% agave |
| Gin (80 proof) | 1.5 oz shot | ~97 kcal | Zero carbs, zero sugar |
| Whiskey (80 proof) | 1.5 oz shot | ~97 kcal | Zero carbs, zero sugar |
| White Rum (80 proof) | 1.5 oz shot | ~97 kcal | Less sugar than dark rum |
| Light Beer | 12 oz (355 ml) | ~103 kcal | Comparable to a single shot |
| Vodka Soda | 7 oz (207 ml) | ~104 kcal | Made with 50ml vodka |
| Margarita | 4 oz (120 ml) | ~168 kcal | Calorie-heavy due to mixers |
| Pina Colada | 7 oz (207 ml) | ~380 kcal | Very high in calories and sugar |
The Low-Calorie Strategy
For those aiming for the lowest calorie consumption, sticking to unflavored, straight spirits is the best strategy. Vodka, tequila, and gin are essentially tied in this category. However, the true difference-maker lies in what you mix with your spirit. A vodka with soda water and a twist of lime is a perfectly legitimate and very low-calorie drink, while a vodka with a sugary mixer becomes a much higher-calorie indulgence. Always choose zero-calorie mixers to keep your total intake in check.
Ultimately, the choice of the absolute lowest-calorie spirit is less critical than the decision to use low-sugar or no-sugar-added mixers. By being mindful of what you add to your drink, you can enjoy spirits without consuming excess calories.

Conclusion
In the final analysis, the difference in calories among standard 80-proof spirits is negligible, with vodka, tequila, and gin all offering the lowest calorie count per shot. A 1.5-ounce shot of any of these spirits contains approximately 96-97 calories, with all calories coming from the alcohol itself, not sugars or carbs. The most significant factor influencing a drink's calorie load is the mixer. By choosing zero-calorie mixers like soda water or fresh citrus, you can keep your total calorie intake minimal while still enjoying a spirit-based drink. For true calorie control, stick to straight spirits or simple, sugar-free combinations.
