Brief Summary
This study will examine appetitive sensation variability and the relationship between appetitive sensations and energy intake. Investigators believe the methods for assessing and interpretation of appetitive sensations are problematic and mask the true influence of these sensations on eating. This limits the development of guidelines for weight management. To gain a better understanding of the relationship, investigators will track hourly appetite sensations and map these to eating events via time-series analyses to gain new insights on the directionality and magnitude of these relationships. Also, investigators will also examine the association of apetitive ratings with age or gender. This will allow the development of more effective weight management recommendations.
