FitDexWater: how many calories?
Water carries 0 calories per 100 grams; a typical portion (250 g) comes to 0 calories. The tables below give the same figure in cups, spoons and slices.

- Carbs0.0 g

What do these numbers mean on the plate?
Water carries 0.0 calories per gram: it takes — grams to reach 100 calories. In this band the portion is hard to misjudge by eye, because piling up calories means genuinely filling the plate.
A typical portion is 250 g. Because tables are written per 100 grams, counting the portion as 100 grams too is a common mistake; for Water that means understating the calories by 60%.
Calories in a drink go down without chewing, so they turn into little sense of fullness; the same calories from solid food would have covered part of a meal.
Household measure equivalents
| Measure | Gram | Calories | Protein |
|---|---|---|---|
| Small glass (100 ml) | 100 g | 0 kcal | 0.0 g |
| Glass (200 ml) | 200 g | 0 kcal | 0.0 g |
| US cup (240 ml) | 240 g | 0 kcal | 0.0 g |
| Can / bottle (330 ml) | 330 g | 0 kcal | 0.0 g |
| Bowl (300 ml) | 300 g | 0 kcal | 0.0 g |
| 1 serving | 250 g | 0 kcal | 0.0 g |
A household measure measures volume and a scale measures weight; what links the two is the food's bulk density, and the table goes that way round. The same cup holds 10-20% more once the contents are packed down or chopped finer. Convert your own measure
How much of the daily reference intake?
| Nutrient | Daily reference | 100 g | 1 portion · 250 g |
|---|---|---|---|
| Calories | 2,000 kcal | 0% | 0% |
| Fat | 70 g | 0% | 0% |
| Carbs | 260 g | 0% | 0% |
| Protein | 50 g | 0% | 0% |
| Fibre | 25 g | 0% | 0% |
The reference values are the figures EU Regulation 1169/2011 gives for an average adult — the %RI column on labels rests on the same numbers. They are not a personal target; the fibre row is not in the regulation, the 25 grams there is EFSA's adequate intake for adults. Work out your own calorie needs
Where does it sit within its group?
It is number 1 of the 13 foods in the Drinks group by calories per 100 grams. The group averages 32 kcal; Water is 100% below that average.
Water is the lowest-calorie food in its group; there is no lighter alternative at the same weight.

Which claims could its label carry?
EU Regulation 1924/2006 ties every label claim to a numeric threshold. Water meets 2 of them:
- Energy-free100 ml → 0 kcal · threshold: at most 4 kcal
- Fat-free100 ml → 0.0 g fat · threshold: at most 0.5 g
The values here are averages; on a real label the thresholds are applied to the product's OWN analysis. The list estimates which claim could be printed and guarantees none of them. For drinks, the calorie and fat thresholds run per 100 millilitres and are lower. Interpret your own label
Apply these numbers to your own portion
- Cups to grams converterCups, spoons, slices, handfuls — all converted to grams and calories. The difference: every food is computed with its own density, because a cup is a volume, not a weight. The same 200 ml glass holds 6.6 g of popcorn and 282 g of honey.
- Food swap calculatorWhat do you gain by replacing something you eat with a lighter alternative at the same weight? 80 foods, computed at your own portion. The difference: it marks the swaps that cut calories without cutting protein and fibre.
- Calorie calculatorEnter your height, weight, age and activity level to see your daily calorie needs, basal metabolic rate and macro split in seconds. The same formula as the FitDex app.
- Calories burned calculatorWork out the calories you burn across 27 activities, scaled to your weight and duration. What sets it apart: it subtracts your resting burn, so you see the extra the exercise actually bought you.
The values are averages taken from standard composition tables; a 10-15% difference between two products with the same name is normal, and the cooking method can double that gap. This page is for information and is not medical advice.
