Brief Summary

In this study, it was aimed to investigate the effect of plate size on food consumption and satisfaction levels in healthy women.

Detailed Description

The effect of plate size on food consumption and satisfaction levels in healthy women aged between 19-35 years will be evaluated in this study. In addition to this, the relationship between the amount of food that women eat and their feelings of satisfaction will be evaluated. During the experiment, the individuals will be asked to consume the pasta with sauce which is offered in the open buffet in the amount of their own determination (ad libitum) using different sized (23 cm and 31 cm) plates. The size of the plates that individuals will use on different experimental days was determined randomly.
