Calories in a banana
The banana carries a reputation for being heavy, and the reputation comes from a weighing mistake: the peel is more than a third of what leaves the shop.
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 banana · peeled flesh | 120 g | 105 kcal | 1.3 g | 23.6 g | 0 g | 3.2 g |
| One small banana · peeled flesh | 90 g | 79 kcal | 1 g | 17.7 g | 0 g | 2.4 g |
| One large banana · peeled flesh | 150 g | 131 kcal | 1.6 g | 29.6 g | 0 g | 4.1 g |
| The Ciqual reference · flesh, no peel | 100 g | 88 kcal | 1.1 g | 19.7 g | 0 g | 2.7 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
- The peel is roughly 35% of a whole banana. A 185 g banana on the scale leaves about 120 g of flesh, and that is the weight the calculation runs on.
- Ciqual measures the banana raw and ripe. A green banana holds more resistant starch, which the body absorbs less well: the figure shown is then an upper bound.
- Plantain is a separate line of the table, with neither the same density nor the same use: it is cooked, and it counts as a starch.

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.
