From pizza photo to food estimate

Watch the Bitepixa walkthrough on YouTube

What can a food diary tell you from a photo of a pizza? We selected the picture below in Bitepixa and ran the scan offline. Follow it from the original photo to the estimate, then check which assumptions you can change.

The pizza photograph used for the on-device scan — Scan input: Margarita Pizza by Douglas Perkins, released under CC0 1.0.

Red outlines and arrows identify the controls or readings discussed in each step.

1. Take a photo or choose one from Gallery

Open Today. Tap Take photo, frame your meal, and take the picture. If you already have a photo, tap Gallery and select it. We used Gallery for this pizza.

Take photo outlined in red on the Today screen — Use Take photo to open the camera.

Gallery button outlined on the Bitepixa home screen — Gallery opens the photo picker.

2. Read the result

The scan identified Pizza. The result card displayed approximately 813 kcal for the estimated portion. That number belongs to this scan of this photograph. A different pizza, crust, topping or portion can give a different result.

Estimated calories card showing approximately 813 kcal and the chosen pizza photo — The result card keeps a thumbnail of the selected picture beside its estimate.

3. Check the portion

Scroll to What’s on the plate. On the Pizza row, the estimated amount is 366.1 g. The camera did not weigh the food. If you know the weight you served, tap the amount, enter that value and review the recalculated estimate. If the food match is wrong, tap Pizza to change it.

Pizza row with the editable 366.1 g amount outlined — The Amount column is editable. This example shows the original estimate.

4. Check the food reference

Expand How this estimate was made. In this example, Bitepixa matched the photo to Pizza, industrially made in the Norwegian Food Composition Table. That description is an assumption to review. The photo alone cannot establish how the pizza was prepared.

Expanded explanation naming the pizza reference and the Norwegian Food Composition Table — Use the listed reference to decide whether the match fits your meal.

When the food and portion look right, choose Mark as eaten if you want the meal counted in your diary.
