A useful food history allows for corrections. Perhaps a portion was smaller, lunch was assigned to the wrong date, or a repeated request created a duplicate. Start by identifying the exact entry so that the correction improves the record without adding another version of the same meal.
Find the entry before changing it
Open Nutrition for the date in question and inspect the meal description. If you are using an assistant, ask it to retrieve the entry first. Two similar lunches on different dates should not be treated as interchangeable.
State what is wrong and what should replace it. 'Change the quinoa portion in October 7's lunch from 150 g to 100 g' is clearer than 'My lunch was too big.' Include enough detail to resolve ambiguity before a write.
Correct the existing record
Use an available edit workflow or ask the connected assistant to update the identified entry through its supported tools. Ask it to retain the meal's date and the details that did not change. A correction should not silently become a second logged meal.
If several entries could match, choose the right one before continuing. If the tool cannot perform the requested correction, return to the app rather than assuming an acknowledgement means the data changed.
- Retrieve the original meal.
- Specify the field or portion that needs correction.
- Resolve any uncertainty about which entry to update.
- Review the saved record and daily totals.
Check the consequences in the daily view
A smaller portion can change several nutrients, not only calories. Review the meal and the day's breakdown after saving. If the total still looks unexpected, look for duplicates or another entry that explains the difference.
Do not infer an exact nutrient change from the example portion alone. Ingredient data, cooked versus uncooked weights, and the original estimate all affect the recorded values.
Treat duplicates as a separate problem
If the issue is two copies of a meal, identify which record should remain and remove only the unintended copy using the supported action. Editing both copies would preserve the double count.
For recurring errors, improve the original logging request or template. A clear meal name and portion convention make later corrections easier to target.
An illustrative example
A targeted correction
Alex retrieves October 7's lunch, changes the recorded quinoa portion from 150 g to 100 g, and checks that only one lunch remains. The guide mockup highlights the portion change without claiming an exact nutrition recalculation.
Keep this in mind
Identify first, correct once, and inspect the saved result.
