Summary

The primary aim of this small study is to test the validity of the Remote Food Photography Method and an updated SmartIntake app in a sample of adolescents. The investigators will test the validity (accuracy) of the method/app at estimating energy intake in free-living conditions over approximately three days compared to doubly labeled water. This is a small study that has low statistical power, but will provide important data nonetheless and inform future research.

Conditions

  • Dietary Assessment
  • Energy Intake
  • Food Intake
  • Food Photography

Interventions

OTHER

Tests of the validity of the RFPM and SmartIntake app.

Participants who enroll will be trained in using the RFPM/SmartIntake app and a food record and will complete the Food Intake Assessment Preference Survey. They will also use both methods to estimate intake during a simulated lab-based meal (they will not eat during this simulated meal). They will be dosed with DLW at this visit and will use the RFPM for the subsequent 1-2 days to get accustomed to using the method, with the following three days comprising the data collection period.
