Study Summary
The objective is to test the accuracy of the PortionSize™ app and the MyFitnessPal© app at measuring energy intake in free-living conditions, tested against the gold-standard, doubly labeled water. Participants will use PortionSize™ and MyFitnessPal apps in separate periods to test the accuracy of the respective apps.
Primary Outcome
Test the equivalence between PortionSize (and MyFitnessPal) and the criterion measure, which is energy intake assessed with DLW. These analyses will rely on equivalence testing using the Two One-side T-test (TOST) method, as well as Bland and Altman analyses.
