How to keep a food log when portions are estimates

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.

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.

Use different labels for different levels of certainty

A packaged portion with a current label, a recipe divided at home, and a café meal with unknown ingredients have different sources of uncertainty. You can preserve all three in a diary without pretending they are equally measured. Add a source note such as “package label,” “recipe estimate,” or “description only.”

If you choose to enter an energy amount, keep its unit explicit. This tool uses kcal. A number copied from a label in another unit should not be pasted into a kcal column unchanged. You can leave the energy field blank while retaining the meal description. Missing information is not an instruction to search until a plausible number appears.

Use the portion calculator only when the inputs match

For an illustrative label with 200 kcal per 50 g, a 75 g portion corresponds to 300 kcal: 200 × 75 ÷ 50. That calculation is traceable because both portion quantities describe the same product in grams. It does not tell you how much to eat, and it does not make an estimated 75 g portion exact.

For a shared dish or a restaurant meal, a description may be a better record than applying a label from a different product. Do not use a generic sandwich entry as though it measured every sandwich. If you later obtain better information, retain a note that the entry was revised rather than presenting the original estimate as certain.

Keep a useful meal record when calorie fields are blank

A food description can answer a practical question even when you do not know the energy value. Start by stating what you wanted to record: one restaurant meal, lunches during a work week, or meals requested by your care team. A record of two meals is still a two-meal record, even if the form has space for an entire day.

The following invented notes show how to preserve what you remember. They are separate examples, not a meal plan, an adequate daily intake or a diagnostic checklist. The unanswered question is part of the record, not a reason to fill in a made-up calorie value.

Check for copied meals on the wrong date and whole-recipe entries counted again as ingredients. Those errors can be corrected without judging the foods. If numerical tracking becomes distressing, use description-only notes or pause and seek support. Completing a diary is not a test you need to pass.

• Use the free food log for descriptions and notes; energy fields can remain blank. You can also print its blank PDF and write only the fields relevant to your purpose.
• Before sharing, add a coverage note such as “two meals recorded; other meals not included.” An empty field means unknown or not recorded, not zero intake.
• If a source becomes available later, add its name and serving basis alongside the estimate. Keep the original rough description so the change is understandable.
• If your care team specifically needs numerical intake records, ask what detail and method they need. This optional format does not replace their instructions.

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.
