A photo is evidence, not a measurement
A meal photo can show visible foods, approximate proportions, preparation clues and sometimes a nutrition label. It cannot reliably reveal the weight of every ingredient, the amount of oil absorbed during cooking, what is hidden under another food, or the exact recipe used by a restaurant. Those missing facts can materially change calories, protein, carbohydrates and fat.
Orzio asks a vision model to identify the likely foods and portions, then returns a structured estimate. The result is designed for a lightweight personal log. It is not the same as weighing ingredients, reading a manufacturer label, or using a recipe with known quantities.
Give the estimate useful context
Frame the complete plate in good light and avoid covering one food with another. A short caption can supply facts the camera cannot see, such as “two eggs,” “fried in one tablespoon of oil,” or a portion weight from the packet. For a packaged product, a readable nutrition label or barcode can be more useful than a styled front-of-pack photo.
Context should describe what you know, not what you hope the result will be. If a restaurant portion or sauce amount is unknown, leave that uncertainty visible rather than turning an estimate into false precision.
- Photograph the whole serving before eating.
- Include a useful size reference when practical.
- Add known quantities, ingredients or cooking fats in the caption.
- Use a nutrition label for packaged food when it is available.
Read trends more carefully than single meals
An isolated estimate may be high or low. A repeated logging habit can still help you notice broad patterns in meal timing, food choices and approximate macro balance, provided you remember that the underlying numbers remain estimates. Do not treat the daily total as laboratory data or use small differences as proof of progress.
If a result is visibly implausible, undo it and log again with better context. Orzio keeps an undone meal in history but excludes it from the active total, so undo is a correction tool rather than account deletion.
Know when not to rely on an estimate
Orzio is not medical or nutritional advice and is not intended to diagnose, treat or manage a health condition. Its estimates can be materially wrong. Do not use them to calculate medication, manage an allergy, make a clinical diet decision, or replace guidance from a qualified professional.
Food-rule checks are based on what the model detects and the rules you saved. Hidden or misidentified ingredients can be missed. If an ingredient matters for safety, confirm it from a reliable source and ask the person who prepared the food.
