The analysis
| Nutrient | Per serving | Whole recipe |
|---|---|---|
| Energy (kcal) | 364 | 728 |
| Protein (g) | 13.9 | 27.9 |
| Carbohydrate (g) | 58.4 | 116.8 |
| Fat (g) | 9.6 | 19.3 |
| Fibre (g) | 5.8 | 11.6 |
| Sugars (g) | 26.2 | 52.4 |
| Salt (g) | 0.22 | 0.44 |
By energy this comes out at 15% protein, 62% carbohydrate and 23% fat, using the Atwater factors of 4, 4 and 9 kcal per gram. A serving weighs about 313 g, which works out at 116 kcal per 100 g of finished dish before any cooking loss.
What each line contributed

| 80 g rolled oats | Rolled oats | 80 | 311 | 13.5 | 5.5 | 43% | weighed |
| 400 ml whole milk | Whole milk | 407 | 248 | 13.0 | 13.4 | 34% | 400 ml at 1.02 g/ml, from typical serving: 1 cup (240 ml) = 244 g |
| 1 banana | Banana | 118 | 105 | 1.3 | 0.4 | 14% | typical serving: 1 medium banana = 118 g |

Every line was recognised and every line carried a measurable quantity, so nothing was left out of the totals.
Reading this recipe
Cooking in milk rather than water roughly doubles the protein of the bowl.
The honey is about a tenth of the calories and almost all of the added sugar.
The single biggest energy contributor is Rolled oats at 43% of the total calories. If you want the dish to be lighter, that is the line to change first — halving it moves the serving by about 78 kcal, which is more than trimming everything else at once.
A serving carries about 5.8 g of fibre and 0.22 g of salt from the ingredients themselves. Salt you add at the table is not in that figure, and it is usually the larger half of what ends up on the plate.
How a pasted line becomes a number
Each line is read in four steps. First the quantity: a plain number, a decimal, a fraction such as 1/2, or a mixed number such as 1 1/2. Then the unit: grams, kilograms, milligrams, ounces and pounds are weights and convert exactly; millilitres, litres, decilitres, tablespoons, teaspoons and cups are volumes; slice, clove, medium and a bare count are whole items. Then the food name, with preparation words such as chopped, fresh or skinless removed and anything after the first comma dropped. Finally the name is matched against the food database.
Volumes and whole items are the part most calculators fudge. A tablespoon of oil and a tablespoon of honey do not weigh the same, so this page does not use one number for both: it looks the food up in the baked USDA food_portion table and uses that food’s own recorded weight for one tablespoon, one cup, one slice or one medium item. Only when the table has no row for that food and unit does it fall back to millilitres at 1 g/ml, and every row that used a fallback says so in its basis column.
Anything that cannot be measured is not guessed. A pinch, a dash, a handful, a knob, “to taste” and a line with no quantity at all are listed separately as excluded, along with any food name the database does not contain. The totals underneath are therefore the total of what is shown as matched, never a padded estimate.
These are database averages for raw or standard-prepared foods. Cooking losses, draining, fat left in the pan, brand differences and how heaped your spoon actually is all move the result. Treat a recipe analysis as a planning estimate, not a measurement, and never as dietary or medical advice — a clinician or registered dietitian is the right place for anything diagnostic.

Frequently asked questions
How many calories are in oat porridge with banana?
About 364 kcal per serving and 728 kcal for the whole recipe as written, from 4 ingredient lines. Change any quantity in the paste box and the figure changes with it.
What is the protein per serving?
13.9 g, which is 15% of the calories in the serving. The rest is 62% carbohydrate and 23% fat.
Is this the cooked weight?
No. It is the sum of the ingredients as listed, 626 g in total, or about 313 g per serving before cooking. Roasting or reducing the dish removes water, so the finished plate is denser per 100 g than this.
