How to keep a food log when portions are estimates

A useful food record can acknowledge uncertainty instead of turning every meal into an exact-looking number.

The useful starting point

Describe the food and portion first. Add energy information only when useful, and identify whether it came from a label, a recipe, or an estimate.

Start with the description

If all you remember is “sandwich from the café,” preserve that rather than selecting a precise-looking database entry that may not match. A text note is still information.

The free log makes calorie amounts optional. You can use it as a meal record without setting a calorie target or grading your food choices.

Use estimates that look like estimates

Write “about,” “roughly,” or a simple range in the notes when you do not know the portion. Avoid implying that an app can measure an unweighed meal exactly.

When a current label is available, keep the product and portion details so you can trace the number. If a recipe changes, update the record rather than reusing an old entry without checking.

Illustrative example

Lunch: café sandwich, portion not weighed. Ingredients partly known. Energy left blank. This is a more honest record than borrowing an exact value from a different sandwich.

Check the record before interpreting it

Look for duplicated meals, missing drinks, and entries copied from the wrong date. These are record-quality issues that you can correct without judging the meal.

If you share a summary, state whether you recorded every day or selected days. An incomplete log should not be presented as a complete measure of intake.

Choose a level of detail that supports you

If tracking makes eating feel distressing or compulsive, pause and seek qualified support. A log should serve a practical purpose agreed with you, not become a test you must pass.
