How to correct a calorie estimate from a meal photo

1. Check the portion

The camera shows area better than weight or depth. Compare the estimated serving with what was actually on the plate, and say whether you ate all of it.

• Use a familiar object, package weight, or menu serving as a reference.
• Mention shared dishes and leftovers.
• Correct the calories and macros if the estimated portion is clearly too large or small.

2. Add what the photo cannot see

Oil, butter, dressing, sauce, sugar, fillings, and preparation method may contribute more than their visible size suggests. Add these details as text or voice context, or attach a useful menu, receipt, or label.

3. Check mixed dishes by their main components

For curries, bowls, casseroles, wraps, and restaurant plates, verify the largest calorie and macro drivers first. You do not need perfect ingredient-level reconstruction to catch a wrong protein portion, an omitted sauce, or a carbohydrate side that was counted twice.

4. Review every value before sync

Read the assumptions, then check the meal name, time, calories, protein, carbohydrates, and fat. MealSync never needs to treat the initial estimate as final: the approved values are the values prepared for Google Health.

The right expectation

A meal photo cannot prove an exact recipe. The goal is a transparent, correctable estimate that is faster than starting from an empty food log—not certainty from a picture.
