Soda water calories come to 0 for a 12 oz can (355 g) and 0 per 100 g. Sodium is the only row that moves: 75 mg per can, or 3% of the daily value. Protein, carbs, fat and sugar all read zero, so portion size changes the sodium total and nothing else.

Every serving size lands on zero calories
Start with the can. A 12 oz can (355 g) of soda water has 0 calories, and a 16 oz bottle (474 g) has 0 as well. The portion grows; the energy count does not. That makes soda water one of the few drinks where measuring the pour changes nothing on the calorie line.
Multiples tell the same story. Two cans come to 710 g of liquid and 0 calories. Three cans reach 1,065 g, still 0. Even five cans, a full 1,775 g, log as 0 calories. If you track drinks, the entry is there for completeness rather than for the math, and you can stop guessing whether that was a small glass or a big one.
What does move with portion size is sodium, covered below. Calories are a flat line. For anyone trying to cut liquid calories, that flat line is the whole appeal: a glass, a can or a bottle costs the same, which is nothing. Few other fizzy drinks on a store shelf can say that without a sweetener doing the work.
There is no protein, carb or fat to split
Most calorie pages break energy into protein, carbs and fat. Soda water breaks into nothing. The calorie split reads 0% protein, 0% carbs and 0% fat, because per 100 g every macro is 0. Sugars are 0, fiber is 0, saturated fat is 0 and cholesterol is 0.
The USDA row behind this page is Beverages, carbonated, club soda, described as carbonated and unsweetened. That second word matters. Plain soda water is water with bubbles and a trace of minerals, so there is nothing in it for the body to use as fuel. The fizz feels like something, but it carries no energy.
That also means soda water does nothing to fill you up the way protein or fiber would. It is a drink for thirst and for the bite of carbonation, not for staying full between meals. If a label on a flavored can shows carbs or sugar, it is no longer the product described here, and those numbers belong on their own line in your log.
Sodium is the only row with a number
Per 100 g, soda water carries 21 mg of sodium and 2 mg of potassium. That is the whole mineral story on the panel, and it is small. Still, it is the one figure on this page that is not zero, so it deserves a look if you drink a lot of the stuff.
A 12 oz can brings 75 mg of sodium, which is 3% of the daily value. A 16 oz bottle brings 100 mg, or 4%. Neither is a large share on its own, and a single can with dinner barely registers next to a salted meal.
It stacks with volume, though. Two cans come to 149 mg, three cans to 224 mg and five cans to 373 mg. If you watch sodium closely and keep a can at your desk all afternoon, those cans are worth counting even though the calories never are. If sodium is not a concern for you, treat the row as minor and move on.
The calories arrive with whatever you mix in
Soda water is often a mixer, and that is where the count changes. Products such as Fullbar Soda Water Cocktail Mixer and Fentimans Traditional Soda Water are sold for drinks, and the soda itself stays at zero while juice, syrup or liquor brings the energy. Log the add-ins separately and the soda water line stays at 0.
Flavored versions need a label check. Cutwater Spirits makes grapefruit, lime and orange soda waters, plus a cucumber cocktail mixer, and Fresca Original Grapefruit Citrus Sparkling Soda Water sits on the same shelf. Flavor can come with or without calories, so the plain club soda numbers on this page apply only to the unsweetened kind.
As an everyday drink, soda water swaps in cleanly for sweetened soda. A squeeze of lime or a few cucumber slices adds flavor without changing the picture much. BodyPal can log the glass from a photo if you want the drink on record.
How does soda water compare?
Here is soda water next to black coffee, black tea and a can of coke, compared per 100 g and per usual serving.
Verdict: For weight loss, soda water and black tea are the cleanest picks at 0 and 2 calories per serving, with black coffee close behind at 5. A can of coke is the outlier at 39 calories and 11 g of carbs per 100 g, so if fizz is what you want, soda water gives it without the carbs.
