A meal photo can often identify visible foods and suggest a reasonable range. It cannot reliably see exact weight, hidden oil, fillings, sauces or recipe quantities. Treat the result as an estimate, review the confidence shown for each item and correct important details.
What the image can help with
- Recognising visible foods and broad preparation styles.
- Separating items on a plate, such as rice, vegetables and chicken.
- Suggesting a portion range when the plate provides useful scale.
- Remembering the meal so your correction refers to a specific entry.
Where uncertainty enters
| Source | Why it matters | What to add |
|---|---|---|
| Portion size | Camera angle can distort volume | Weight, cups or pieces |
| Oil and sauce | Often hidden but energy-dense | Cooking method and amount |
| Mixed dishes | Ingredients overlap | Recipe or menu description |
| Product variation | Brands and recipes differ | Label or restaurant name |
How WazzUp presents uncertainty
WazzUp can show an estimated calorie range and a visual confidence level for recognised items. Confidence describes how sure the visual identification is; it does not guarantee that the portion or nutrition is exact. When confidence is lower, the useful next step is a short clarification or a suggested alternative.
How to improve the estimate
- Photograph the whole plate in good light.
- Include a familiar object or state the portion.
- Name sauces, oils, drinks and anything hidden.
- Use a nutrition label or menu value when one is available.
- Reply to the exact result with the corrected value or food.
Example: “Total for this bowl is 327 calories, and the protein is pesto chicken rather than teriyaki chicken.” A correction like this identifies both the value and the affected entry.
Should you use the number?
Use estimates to understand patterns and make consistent comparisons. Avoid treating a photo-derived number as laboratory measurement. If you need precise nutrition for a medical reason, use a method recommended by a qualified healthcare professional.
