Whether you prefer bourbon, scotch, rye, Irish whiskey, or Japanese whisky, you will learn exactly how each type fits into a healthy drinking approach and which options deliver the best experience for the calories.
The Basic Nutrition of Whiskey
Here is the good news: all pure whiskey, regardless of type, contains zero carbohydrates and zero sugar. The distillation process separates the alcohol from the fermented grain mash, leaving behind any sugars or carbs that were present before distillation.
Standard Nutritional Profile (1.5 oz shot)
| Metric | 80 Proof | 86 Proof | 90 Proof | 100 Proof |
|---|---|---|---|---|
| Calories | 97 | 105 | 110 | 124 |
| Carbs | 0g | 0g | 0g | 0g |
| Sugar | 0g | 0g | 0g | 0g |
| Fat | 0g | 0g | 0g | 0g |
| Protein | 0g | 0g | 0g | 0g |
The only variable affecting whiskey calories is the alcohol content (proof). Higher proof means more alcohol, which means more calories since alcohol contains 7 calories per gram. A 100 proof whiskey has about 28% more calories than an 80 proof whiskey.
Types of Whiskey Explained
Bourbon
American whiskey made from at least 51% corn, aged in new charred oak barrels. The corn base gives bourbon a sweeter flavor profile, but this does not translate to actual sugar content. Popular brands include Maker’s Mark, Buffalo Trace, Wild Turkey, and Woodford Reserve.
Nutrition: Same as all whiskey. Zero carbs, zero sugar. Calories vary only by proof.
Best for dieters: The sweeter taste profile can satisfy dessert cravings without sugar.
Scotch Whisky
Scottish whisky made primarily from malted barley, aged at least three years. Can be single malt (one distillery) or blended. Often has smoky, peaty notes from the malting process. Popular brands include Glenfiddich, Macallan, Johnnie Walker, and Lagavulin.
Nutrition: Identical to other whiskeys. Zero carbs, zero sugar.
Best for dieters: Complex flavors encourage slow sipping, which can mean less overall consumption.
Rye Whiskey
Made from at least 51% rye grain. Spicier and more peppery than bourbon. Popular in classic cocktails like Manhattans and Old Fashioneds. Brands include Bulleit Rye, Rittenhouse, and WhistlePig.
Nutrition: Same as all whiskey. Zero carbs, zero sugar.
Best for dieters: The spicy character provides strong flavor without sweetness.
Irish Whiskey
Triple distilled whiskey from Ireland, known for smooth, approachable character. Less smoky than scotch, less sweet than bourbon. Brands include Jameson, Bushmills, Redbreast, and Tullamore Dew.
Nutrition: Identical to other whiskeys. Zero carbs, zero sugar.
Best for dieters: Smooth enough for neat sipping even for whiskey newcomers.
Japanese Whisky
Made in Japan, often following Scottish traditions with unique Japanese refinements. Known for exceptional quality and balance. Brands include Suntory Yamazaki, Nikka, and Hibiki.
Nutrition: Same as all whiskey. Zero carbs, zero sugar.
Best for dieters: Premium options encourage savoring rather than rapid consumption.
The Flavored Whiskey Warning
While pure whiskey has zero carbs and sugar, flavored whiskeys are a completely different story. These products add sugar and other flavoring agents that dramatically change the nutritional profile.
Flavored Whiskey Examples
| Product | Calories (1.5 oz) | Carbs | Sugar |
|---|---|---|---|
| Fireball Cinnamon | 108 | 11g | 11g |
| Jack Daniel’s Tennessee Honey | 108 | 6g | 6g |
| Jim Beam Apple | 100 | 8g | 8g |
| Crown Royal Apple | 100 | 8g | 8g |
| Skrewball Peanut Butter | 110 | 10g | 9g |
Fireball contains 11 grams of sugar per shot. That is equivalent to almost three teaspoons of sugar. A few shots of Fireball on a night out can add 50 or more grams of pure sugar to your intake.
Rule: If whiskey has a flavor name on the label (honey, apple, cherry, cinnamon, peanut butter), assume it contains significant added sugar and check the nutrition facts.
Best Ways to Drink Whiskey for Diet Conscious Drinkers
Neat (Best Option)
Drinking whiskey neat means straight from the bottle into a glass, no ice, no water, no mixer. This is the purest way to experience whiskey and the most diet friendly option since you add nothing to the base spirit.
Calories: 97 per 1.5 oz (80 proof)
Carbs: 0g
On the Rocks
Whiskey served over ice. The ice dilutes the whiskey as it melts, which can make it more approachable for beginners and slows down consumption. Ice adds nothing nutritionally.
Calories: 97 per 1.5 oz
Carbs: 0g
With Water
Adding a small amount of water opens up the aromas and flavors of whiskey. Many whiskey experts actually recommend this for tasting. Water adds zero calories or carbs.
Calories: 97 per 1.5 oz
Carbs: 0g
With Club Soda (Highball)
A whiskey highball combines whiskey with club soda over ice. This Japanese style of serving stretches a pour of whiskey into a longer, more refreshing drink without adding calories.
Calories: 97 per drink
Carbs: 0g
Mixers to Avoid
- Regular cola: Adds 140+ calories and 39g sugar per can
- Ginger ale: Adds 120+ calories and 32g sugar
- Sweet vermouth: Adds 45+ calories and 4g carbs per ounce
- Juice: Orange, apple, cranberry all add significant sugar
- Simple syrup: Pure sugar, adds 50+ calories per tablespoon
Acceptable Mixers
- Diet cola: Zero calories, zero carbs
- Club soda: Zero calories, zero carbs
- Diet ginger ale: Zero calories, zero carbs

Whiskey and Keto: A Perfect Match
Pure whiskey is one of the most keto compatible alcoholic beverages available. With zero carbs and zero sugar, it has no impact on your carbohydrate limits. You could theoretically drink whiskey all day without consuming a single carb (though we do not recommend this for other reasons).
Keto Whiskey Guidelines
- Stick to pure whiskey: No flavored varieties
- Avoid sweet mixers: No cola, no juice, no simple syrup
- Choose zero carb mixers: Club soda, diet soda, water
- Watch for hidden carbs: Some cocktails use sweet vermouth or liqueurs
- Remember alcohol pauses ketosis: Your body processes alcohol before fat
