Summary

This study checked if the PortionSize and MyFitnessPal apps accurately measure how many calories people eat in everyday life. 63 adults used each app for a set time, and researchers compared the app results to a very precise method called doubly labeled water. The goal was to see if these apps can reliably track energy intake outside of a lab.
