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).
