How to record oil, sauces and ingredients a photo cannot show
A photo can help you start a food record, but it does not show everything in the dish. Cooking oil, a dressing or a filling may be hidden. Reviewing them gives the estimate useful context.

1. Review what the photo suggests
Check every identified food and remove anything that was not on the plate. Add missing ingredients such as oil, butter, sauce, filling, sugar or a side dish. An image cannot confirm the recipe or rule out allergens; check the product information or ask whoever prepared the food.
2. Measure the quantity you actually use
When you cook, weigh oil or sauce before adding it. You can use a small container and the scales’ tare function. Confirm whether the nutrition entry uses values per 100 g or 100 ml. A spoonful is not always the same amount, and grams and millilitres are not automatically interchangeable.
3. Divide ingredients across the recipe
For illustration, if you add 20 g of oil to an evenly mixed dish with four equal portions, each portion accounts for 5 g. Do not record all 20 g for every plate. DietaGo uses the confirmed entry and weight to calculate nutrients; the example quantities are not a recommendation.
4. Acknowledge what you cannot measure
Oil left in the pan or sauce that is discarded is not necessarily consumed. A photo also cannot tell you how much oil fried food absorbed. If you eat out or do not know the recipe, enter a reasonable estimate and keep that uncertainty in mind when reading your daily summary.
5. Confirm and save the reviewed version
Before saving, check the preparation state, weight and nutrients for every ingredient. If you make the dish again, you can save it as a measured dish. Review quantities whenever they change. Your review improves the record, but it does not turn an estimate into a laboratory analysis.
