Biological Assessment of Satiety

Why are we doing this study?

The study is being done to develop a method to assess the satiety of food items that correlate the subjective (questionnaire responses) and objective (gut hormone levels) response to food intake, and to determine the extent to which commonly consumed foods influence satiety responses.
