Moodwell Updated September 20, 2026 3 minute read In brief Use the restaurant’s own information when it describes your order, or choose a reasonable food estimate and review its ingredients and portion. Record what you know without treating an unknown recipe as a measured meal. In this guide 1.

[Remember the estimate when you review the week](https://www.moodwell.ai/guides/logging-restaurant-meals-with-uncertainty#later-review) ## Begin with the information that belongs to your order A restaurant name alone does not identify a meal. The dish, size and substitutions all matter to the record you choose. If the restaurant provides information for the exact item you ordered, use it as a reference when checking the food result. Read whether sides, drinks or optional additions are included. For a local restaurant with no matching food in your history, describe the dish using the ingredients you know. A photo can help you recall the plate, but it cannot confirm the full recipe. Review the resulting estimate rather than repeatedly rerunning a capture in the hope that an unknown recipe will become exact. ## Separate visible components from assumptions You may know that your order contained rice, grilled vegetables and chicken while remaining unsure about the sauce. Those facts are useful even though the whole meal is uncertain. Do not add confidently measured ingredient amounts unless you have a basis for them. A detailed invented recipe is still an invented recipe. Watch for duplicate components when combining entries. If the main dish record already includes its side, logging the same side separately counts it twice. Conversely, a record for a sandwich alone may not include the fries that came with your order. Read the description before deciding what belongs together. ## Worked example: a shared pizza and your own drink Two people share a pizza, and you eat two of its eight similarly sized slices. Start with a record for that pizza style and read whether its serving means one slice or the whole pizza. If it means a slice, your portion is two slices; if it means the whole pizza, your share is one quarter. Add your drink separately if it is not part of the pizza record. If a slice serving is based on a different pizza size, recognize that the match is approximate. The entry documents what you can reasonably reconstruct. It does not become exact because the daily total displays a single number. ## A quick check before leaving the meal behind - Read the dish description and serving basis. Confirm whether the food represents your order, a generic alternative or just one component. - Include known extras and substitutions without counting items that are already included in the main dish record. - Adjust for your share and any amount you left. A plated serving and an eaten serving can be different. - Confirm the date and meal, then save the best supported estimate. Repeatedly changing small assumptions is unlikely to resolve an unknown recipe. ## Remember the estimate when you review the week A restaurant entry can make the diary more informative than a blank meal while still carrying uncertainty. When comparing days, consider which records came from known packages or recipes and which were approximate. Use that distinction to judge how strongly the numbers support a conclusion, especially when the apparent difference between days is small.
