    Quick answer

    An AI calorie counter uses image recognition to estimate dish and portion from a photo. Shonkoff et al. (2023) reviewed 52 studies; 79 percent of them used convolutional neural networks for food detection and classification.

    How an AI calorie counter works

    The AI first detects which foods are in the photo and then estimates their amounts. Calories and macros are calculated from food and amount. In the review by Shonkoff et al. (2023), 79 percent of studies used convolutional neural networks for detection and classification.

    What research says about accuracy

    Average relative errors for calories ranged from 0.10 to 38.3 percent across the reviewed studies. Because image databases and reporting varied widely, no meta-analysis was possible. The authors recommend testing AI models on a limited number of large reference databases in the future.

    The scanner on this page uses a current multimodal AI model. The result is an estimate; the listed ingredients show how it was calculated.
