Calories in an orange
The citrus of breakfast and of afternoon segments, weighed as flesh: the peel stays on the table, not in the count.

What a real portion weighs
The Anses table gives values per 100 grams, and 100 grams is not a portion anybody serves. Here are the same values, applied to the portions as they turn up. Weights are in grams, the unit the table is built on. For a quick conversion: 1 oz is about 28 g, and 1 lb is about 454 g.
| Portion | Weight | Energy | Protein | Carbs | Fat | Fiber |
|---|---|---|---|---|---|---|
| One medium orange · peeled | 130 g | 55 kcal | 1 g | 10.4 g | 0 g | 3.5 g |
| Half an orange | 65 g | 27 kcal | 0.5 g | 5.2 g | 0 g | 1.8 g |
These weights are usual orders of magnitude, not standardized measures: they turn a per-100-gram value into a credible portion. A kitchen scale stays more accurate than any average weight.

What a table of values does not say
- Squeezed, the orange loses its pulp and its fiber: the juice of an orange is no longer quite the orange, and it goes down three times faster than the fruit is eaten.
- The peel is a quarter of the weight bought: this page weighs what gets eaten.
What comes after the number
How much to eat in a day
A portion means nothing without the day that holds it. A calorie need is worked out from height, weight, age and activity level, then split into protein, carbohydrate and fat.

An average weight is an estimate. A photo is not.
In Zemiam, a photo of the meal is enough to log the real portion, with the composition of this same table rather than a guessed figure.
Where the values come from
The composition comes from the Anses Ciqual table: Anses. 2025. Table de composition nutritionnelle des aliments Ciqual, published under Licence Ouverte 2.0. The per-100 g values are reproduced without being altered; the per-portion values are those same values multiplied by a weight, and that weight is not an Anses figure.
