Adherence
The Remote Food Photography Method (RFPM) provides reliable and valid estimates of energy intake in free-living conditions, with significantly lower error rates (approx. 5%) compared to traditional self-report methods (37%+).
If you need to track food intake accurately without the guesswork of portion sizes, using a camera to photograph your meal and plate waste is a viable, objective method. It reduces the cognitive burden of estimation and provides data comparable to weighing food, with only a small, consistent underestimation bias.
The degree of error for the RFPM was very small (-4.7 to -6.6%) when compared with error of 37% or more associated with self-report methods, and the error was similar in both laboratory and free-living conditions.
Why this rating
Controlled laboratory and free-living trials with n=52, high inter-rater reliability, and comparison against weighed gold standard.
