Low Calorie Alcohol: What to Drink on a Diet
TL;DR: The lowest calorie alcoholic drinks are spirits with a zero-calorie mixer — a vodka soda comes in at about 133 calories. For wine, a dry white or rosé is around 120 calories a glass, or you could try SkinnyProsecco at 63. Light beers sit around 89-100 calories a can. The drinks to avoid are cocktails, cream liqueurs, and anything with sugary mixers. The NHS says stick to fourteen units a week maximum.
Alcohol has calories. Quite a lot of them, actually. A single night out can add 500 to 1,000 calories to your week — the equivalent of an extra meal — and none of it comes with any nutritional benefit whatsoever. That doesn’t mean you have to stop drinking entirely to lose weight. But knowing which drinks are the worst offenders and which ones are relatively harmless makes a genuine difference if you’re trying to stay in a calorie deficit.
The Calorie Problem With Alcohol
Alcohol contains 7 calories per gram. That puts it closer to fat (9 cal/g) than to carbohydrates or protein (4 cal/g each). And these are empty calories — no vitamins, no minerals, no fibre, nothing your body actually needs.
Why Your Diet Stalls When You Drink
When alcohol enters your system, your metabolism basically puts everything else on hold and deals with the booze like it’s a fire alarm. Fat burning pauses. Sugar processing slows down. Your liver gets stuck processing the ethanol, and the food you ate with your drinks gets stored rather than burned. Then there’s the snack cascade. A couple of drinks lowers your inhibitions just enough that the kebab shop on the way home starts looking reasonable.
Lowest Calorie Alcoholic Drinks — Ranked
1. Spirits
Clear spirits neat or with a diet mixer are your lowest-calorie option. A 25ml shot of vodka, gin, or tequila has about 97 calories. A vodka soda comes in at around 133 calories total.
2. Hard Seltzers & Light Beer
Hard seltzers range from 70 to 100 calories per can. Light beers like SkinnyBrands come in at about 89-100 calories per can or bottle.
3. Wine
Dry white or rosé wine has around 120 calories per 175ml glass. SkinnyProsecco is even lower at 63 calories. Standard lager has 140 calories, and red wine is 125-150 per glass.
Spirits — Your Lowest-Calorie Starting Point
A single 25ml measure of vodka, gin, or tequila has about 97 calories. A vodka and soda water is around 133 calories total. A gin and slimline tonic, roughly 110. But use regular tonic and that same gin drink jumps to 170.
The Mixer Trap
Your mixer can double your drink’s calorie count. Regular tonic water: 80 calories per 200ml. Coca-Cola: 90 calories. Orange juice: over 100 calories. The fix is simple — soda water, slimline tonic, diet cola, or neat.

Frequently Asked Questions
Q1: What is the absolute lowest calorie alcohol?
A1: A 25ml shot of vodka, gin, or tequila at about 97 calories. Mix with soda water to keep the full drink under 133 calories.
Q2: Can I drink alcohol and still lose weight?
A2: Yes, but you have to count those calories like you would food. A few vodka sodas on a Friday night won’t wreck your deficit if you’ve planned for them.
Q3: How many calories are in a gin and tonic?
A3: About 170 with regular tonic. Switch to slimline tonic and it drops to roughly 110. The gin itself is only 97 calories.
Q4: Does wine have fewer calories than beer?
A4: A glass of dry white (120 cal) beats a pint of lager (180-200 cal). But a light beer at about 100 calories is actually lower than most wine.
Q5: Is vodka actually the healthiest option?
A5: “Healthiest” is a stretch for anything with alcohol in it. But in terms of calories, zero carbs, and zero sugar — vodka with a diet mixer is as clean as it gets.
Q6: Are these skinny beers and wines any good?
A6: They’ve improved a lot. SkinnyBrands lager tastes like a normal light lager. SkinnyProsecco is perfectly drinkable.
Q7: How often can I drink and still stay in a calorie deficit?
A7: That depends on your total budget. Two vodka sodas twice a week adds about 530 calories. Most people can absorb that.
Q8: A common belief is that red wine is the healthy option.
A8: Red wine contains antioxidants but calorie-wise, it’s higher than white or rosé — around 125 to 150 per glass. For weight management, dry white is the better call.
Conclusion
You don’t need to quit. You just need to know what you’re drinking. Spirits with zero-calorie mixers are your best bet. Light beers and seltzers are solid alternatives. Wine is fine if you stick to dry white or rosé. Track the calories like you would any other food.
