Plain vodka has zero carbs and about 97 calories per 1.5 oz shot, which makes it one of the most keto-friendly alcoholic drinks you can order. All the carbs in a vodka drink come from the mixer, not the vodka — so a vodka soda is nearly carb-free while a vodka cranberry can top 15g. Here's the breakdown.
Carbs and calories in vodka
| Vodka (1.5 oz shot) | Carbs | Calories |
|---|---|---|
| 80 proof (40% ABV) | 0g | ~97 |
| 90 proof | 0g | ~110 |
| 100 proof | 0g | ~124 |
| Flavored vodka | 0–5g+ | ~100+ |
Distillation removes sugars and carbohydrates, so pure spirits — vodka, whiskey, tequila, gin, and rum — all come out carb-free. The calories come entirely from the alcohol itself (about 7 calories per gram).
Why vodka is keto-friendly
Vodka fits keto because it adds zero net carbs to your day. The catch is what goes in the glass with it. The carbs come from mixers:
- Vodka soda: ~0g — vodka + club soda + lime ✅
- Vodka + diet soda: ~0–1g ✅
- Vodka martini (dry): ~1g ✅
- Vodka tonic: ~16g — regular tonic is sugar water ❌ (use diet tonic)
- Vodka cranberry: ~15–30g — juice ❌
- Vodka Red Bull: ~27g — regular energy drink ❌ (use sugar-free)
The best low-carb vodka mixers
To keep a vodka drink keto, mix it with something that has no sugar:
- Soda water / club soda — 0g, 0 calories
- Diet tonic water — ~0–1g (regular tonic has 32g!)
- Diet soda / Coke Zero / Sprite Zero — 0g
- Sugar-free flavored seltzer (like a splash of lime seltzer) — 0g
- Fresh lime or lemon juice — ~1g per wedge
- Sugar-free drink mixes (Crystal Light, Mio) — ~0g
Avoid regular tonic, juice, regular soda, and energy drinks — that's where a "zero-carb" vodka turns into a sugar bomb.
Drinking vodka on keto
Vodka won't add carbs, but the alcohol still pauses fat-burning while your body metabolizes it, and it tends to hit faster and harder in ketosis. Sip slowly, alternate with water, and don't let a few drinks loosen your grip on food carbs later in the night.
The easiest way to keep drinks keto is to track them. CarbMeNot shows the net carbs for spirits, mixers, seltzers, and cocktails, and logs them from a photo — free on iOS and Android. See keto cocktails, the low-carb alcohol guide, and check any drink with the free Is It Keto? tool.
Frequently asked questions
- How many carbs are in vodka?
- Plain distilled vodka has zero carbs. A standard 1.5 oz shot has about 97 calories, all from the alcohol itself, and no carbs, sugar, or fat. Flavored and 'infused' vodkas can contain added sugar, so check the label, but unflavored vodka is carb-free.
- Is vodka keto-friendly?
- Yes — vodka is one of the most keto-friendly drinks because it has zero carbs. The only carbs come from what you mix it with, so pair it with soda water, diet soda, or fresh citrus rather than juice, tonic, or regular soda.
- How many calories are in a shot of vodka?
- A 1.5 oz shot of 80-proof vodka has about 97 calories. Higher-proof vodka has more — roughly 110 calories for 90-proof and 125 for 100-proof — because the calories come from the alcohol content.
- Does vodka have sugar?
- Plain vodka has no sugar and no carbs. Flavored vodkas (whipped, vanilla, citrus, etc.) may have added sugar, so read the label. Stick to unflavored vodka to keep it zero-carb.
- What is the best low-carb vodka mixer?
- Soda water (club soda) is the best — zero carbs and calories. Diet soda, diet tonic, Coke Zero, sugar-free flavored seltzer, and fresh lime or lemon are all keto-friendly. Avoid regular tonic (32g sugar per 12 oz), juice, and regular soda.
