Where the calories come from
Calories come from three macronutrients: protein and carbohydrate at 4 kcal per gram, fat at 9 kcal per gram. For orange (raw) the split is:
- Protein: 0.9 g × 4 = 4 kcal — 7% of calories
- Carbohydrates: 11.8 g × 4 = 47 kcal — 91% of calories
- Fat: 0.1 g × 9 = 1 kcal — 2% of calories
- Most of the energy in orange (raw) comes from carbohydrate (91% of calories).
- 9.4 g of its carbohydrate per 100 g is sugar.
- It is 87% water, which is why it is so light for its size.
- For 200 kcal you can eat about 425 g.
What actually changes the number
Peeled weight is what counts: a 180 g orange loses roughly a quarter of its weight to peel. Juice concentrates the sugar without the fibre — a glass of orange juice is two to three oranges' worth of calories and none of the chewing.
How accurate are these numbers?
The values on this page are reference averages from the USDA FoodData Central database (SR Legacy release), measured on samples of orange as sold and prepared in the United States. Your portion will differ: produce varies by variety and ripeness, meat by cut and trim, and anything cooked by the fat and water it gained or lost.
For most foods the per-100 g figure is reliable to within about 10%. The larger uncertainty is almost always the weight of what is on your plate and the cooking fat you cannot see — the two things worth checking before you worry about the database.

Can I track orange by taking a photo?
