Meal logging guide for Google Health

A photo calorie estimate you can correct before Google Health

A meal photo is a useful starting point, not the whole answer. MealSync turns the visible food plus the context you add into an editable nutrition estimate, shows the assumptions, and waits for your approval before creating a Google Health record.

What a meal photo can—and cannot—show

A photo can identify visible foods and suggest portion size. It cannot reliably reveal hidden oil, sauce, recipe quantities, preparation details, or how much you left behind. MealSync keeps those uncertainties visible instead of treating the first estimate as a fact.

  • Use the whole plate in the frame when possible.
  • Add a portion reference or package label when it helps.
  • Describe hidden ingredients and the amount actually eaten.

Add the context the image is missing

Use the photo alone for a simple meal, or combine it with a menu, receipt, label, typed detail, file, or voice note. These inputs belong to one flexible meal workflow—not separate logging modes.

Correct the estimate instead of starting over

Review the meal name, time, calories, protein, carbohydrates, fat, and short assumptions. Change any field that does not match what you know about the meal. The useful test is whether correction is faster than rebuilding the meal ingredient by ingredient.

Approve one structured record

After approval, MealSync writes one structured nutrition-log record to Google Health. The source photo and other context are not included in that Google Health record.

The data boundary

MealSync sends the reviewed nutrition record—not your source photo, receipt, menu, label, or voice content—to Google Health.
