How to calculate the calories and macros in a recipe

What you need

• A recipe in your kitchen, imported, scanned or typed
• An ingredient list with quantities on it
• No AI use to look at the numbers

Step by step

1. Import or write the recipe

Every route ends in the same place: a recipe with an ingredient list. Nutrition is calculated from that list, so the more honest the quantities, the more honest the figures.

2. Open the nutrition on the recipe

You get calories, protein, carbohydrates, fat and fibre, both per serving and for the recipe as a whole.

3. Fix the quantities that were vague

“A drizzle of olive oil” is 120 calories or 400 depending on the drizzle. Ingredients with real amounts on them are the ones that move the estimate, so put a number on the oil, the butter and the cheese first.

4. Set the servings honestly

Per-serving figures are only as good as the serving count. A tray that says four and feeds three is a third out.

5. Use the number to change the meal

This is what the estimate is for. Get this under 600 calories per serving or add 30g protein rewrites the recipe and gives you the new figures to compare.

6. Watch the week, not just the plate

Once meals are on your plan you can see a day’s total and a week’s total, which is a more useful view than any single dinner.

When it does not work

• A figure looks wildly wrong. Check the ingredient list for a unit slip. 500g of parmesan instead of 50g does exactly this.
• An ingredient was not recognised. Rewrite the line with the amount first: 200g chickpeas rather than chickpeas, a tin.
• Your recipe has no quantities. A social caption often does not. The estimate needs amounts, so add them.
• You need micronutrients. Tableful estimates the five figures above. A dedicated nutrition tracker goes deeper, and the comparisons on this site say which one to use for what.

Questions people ask

How accurate is it?

Accurate enough to choose between two dinners and to hit a protein target roughly. It is an estimate from an ingredient list, not a laboratory measurement, and it is not medical advice.

Do I have to log what I eat?

No. Tableful attaches nutrition to recipes and to plans, not to a diary. Nothing has to be logged after the fact for the numbers to be useful.

Does viewing nutrition cost an AI use?

No. Viewing nutrition, planning, groceries and cooking mode are all free and unlimited on every plan.
