Logging a snack or a quick lunch should not mean typing out every number on the package. With CaloriePilot, start with a photo of the nutrition label and the amount you ate.

Here is how to log half a 400 g pack of rice noodles and keep the meal in your food diary.

1. Photograph the nutrition label

Keep the whole nutrition table and the package weight in focus. If they are on different sides, take two photos. This package weighs 400 g, while the table lists values for 100 g.

The table is per 100 g. The 400 g printed above it is the weight of the whole pack.

2. Enter your portion and save

Open AI Assistant, attach the label photo, and say what you ate—for example, “I ate 200 g of this for lunch.” Half of this 400 g pack is 200 g.

Check the food and portion, then confirm to save. Your diary keeps the meal and its calories together.

Why half a pack is not always one serving

Look for “per 100 g” or “per serving” on the label. This pack lists values per 100 g, so eating 200 g means twice the listed amount. Tell CaloriePilot your portion to help match the record to what you ate.

If the label says “per serving”

On this label, one 170 g box is one serving and contains 220 kcal. Two boxes contain 440 kcal. A package can contain several servings, so check the serving size on the food you are eating.

Before saving, check three things

  • Is the label for 100 g, one serving, or the whole pack?
  • Does the portion match how much you ate?
  • Did you add anything else, such as oil, sauce, or milk?

No label? Start with a meal photo

Eating out or cooking at home? Start with a meal photo. CaloriePilot can help estimate the calories when there is no label to scan.

Common questions

Can I scan a nutrition label instead of entering every nutrient?

You do not need to start by typing every nutrient. Attach a clear label photo in CaloriePilot, add how much you ate, and check the information before saving.

How do I convert kJ on a food label to calories?

Divide kJ by 4.184 to get kcal. For example, 572 kJ is about 137 kcal.

Does “per serving” mean the whole package?

Only when the whole package is one serving. Check the serving size and servings per container. Two servings generally contain twice the listed calories and nutrients.

What if the label is blurry or partly hidden?

Retake it in good light, keeping the whole nutrition table and serving size in focus.
