Brief Summary

The purpose of this investigation is to validate a passive image-assisted dietary assessment method using images taken by Sony Smarteyeglass and an automatic image analysis software, DietCam, to identify food items and estimate portion sizes. Participants will be randomized into one of the two orders of meals (Order 1 and 2). In each meal, participants will be given a meal that includes a regular-shaped single food (i.e., cookie), an irregular-shape single food (i.e., ice cream), a regular-shaped mixed food (i.e., sandwich), and irregular-shaped mixed food (i.e., pasta dish).

Conditions

Diet Habit

Outcome Measures

Primary Outcomes (2)

• Weighed Food Intake

  Before and after each meal session, each food items will be weighed to the nearest tenth of a gram using an electronic food scale. Assessing the weight change of food intake.

  Meal session 1 and 2 within 4 weeks of initial screening session

• 24-hour Dietary Recall

  On the following day of each meal session, the investigator will ask the participant to recall their dietary intake by having the participant reporting all foods and beverages consumed and the time in which they consumed these items within the past 24 hours. Participants will be asked what time of day the foods and beverages were consumed and will be shown two-dimensional food shapes to help with estimating portion sizes. Only dietary intake for the meal session will be entered into NDS-R to convert to commonly used measurements.

  The following day of meal session 1 and 2 within 4 weeks of initial screening session
