FitDexOrange: how many calories?
Orange carries 47 calories per 100 grams; a typical portion (150 g) comes to 71 calories. The tables below give the same figure in cups, spoons and slices.
- Protein0.9 g
- Carbs12.0 g
- Fat0.1 g
- Fibre2.4 g
- Protein1.4 g
- Carbs18.0 g
- Fat0.2 g
- Fibre3.6 g
Where do the calories come from?
- Protein 7%
- Carbs 91%
- Fat 2%
The shares are calculated from the calorie value of the macros: protein and carbohydrate are 4 calories per gram, fat is 9. Fibre is counted inside the carbohydrate and there is no alcohol in this list, which is why the three shares always add up to one hundred percent.
What do these numbers mean on the plate?
Orange carries 0.5 calories per gram: it takes 213 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 150 g. Because tables are written per 100 grams, counting the portion as 100 grams too is a common mistake; for Orange that means understating the calories by 33%.
In calories, one portion (150 g · 71 kcal) comes to: 157 g Orange juice. Orange juice page
One portion every day adds up to 25,733 calories a year — roughly a 3.3 kg difference. This is a linear estimate and an upper bound: as weight changes, daily needs change with it. Build your own timeline
In fruit and vegetables the calories are diluted by water; the dried form is several times denser at the same weight.
Household measure equivalents
| Measure | Gram | Calories | Protein |
|---|---|---|---|
| Tablespoon (15 ml) | 11 g | 5 kcal | 0.1 g |
| Small glass (100 ml) | 75 g | 35 kcal | 0.7 g |
| Glass (200 ml) | 150 g | 71 kcal | 1.4 g |
| US cup (240 ml) | 180 g | 85 kcal | 1.6 g |
| Bowl (300 ml) | 225 g | 106 kcal | 2.0 g |
| 1 medium | 150 g | 71 kcal | 1.4 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 · 150 g |
|---|---|---|---|
| Calories | 2,000 kcal | 2% | 4% |
| Fat | 70 g | 0% | 0% |
| Carbs | 260 g | 5% | 7% |
| Protein | 50 g | 2% | 3% |
| Fibre | 25 g | 10% | 14% |
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 8 of the 12 foods in the Fruit and vegetables group by calories per 100 grams. The group averages 51 kcal; Orange is 8% below that average.
Lighter options at the same 150 grams
| Food | Calories | Difference | Protein |
|---|---|---|---|
| TomatoGood swap | 27 kcal | −44 kcal | 1.4 g |
| Spinach — boiledGood swap | 35 kcal | −36 kcal | 4.5 g |
| StrawberryGood swap | 48 kcal | −23 kcal | 1.0 g |
The “good swap” mark only appears when an option lowers the calories without also lowering protein and fibre per 100 calories. Unmarked rows save calories but give up nutrient density. Try it with your own portion
How long does it take to burn one portion (150 g)?
- Walking — brisk (5.6 km/h)17 min
- Running — 8 km/h (7:30 min/km)8 min
- Cycling — 16-19 km/h10 min
The times are for someone weighing 70 kilos and use NET burn: the resting calories that would have been spent anyway over the same period are subtracted. The heavier the person, the shorter the time. Calculate with your own weight

Which claims could its label carry?
EU Regulation 1924/2006 ties every label claim to a numeric threshold. Orange meets 2 of them:
- Fat-free100 g → 0.1 g fat · threshold: at most 0.5 g
- Source of fibre100 kcal → 5.1 g fibre · threshold: at least 1.5 g
The thresholds apply to a product's OWN analysis; the values here come from average composition tables. So this list is not an authorisation, only an estimate of which side of the threshold a product sits on. For drinks the energy and fat thresholds are per 100 millilitres and lower.

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.
