Physiological and Eating-behavioral Responses to Viewing Sensory-specific Food Pictures

The overall objective of the research project is to characterize the consequences of digital food stimuli exposure on eating behavior. Specifically, we aim to study cephalic phase physiology, food choice and quantity, as well as post-ingestive sensations in response to viewing sensory-specific food pictures. Furthermore, we want to examine whether these outcomes depend on sweet taste liking, as determined by FGF21 concentrations in the blood and the phenotypical Sweet Taste Liker Test. Section 2.1 lists the primary hypotheses.
