Background summary
In view of the obesity epidemic, it is important to understand how exposure to
food cues, for example, the smell of freshly baked bread, can influence food
choice and intake by enhancing appetite and salivation
Study objective
To determine appetite responses to different odors (signalling different food
products), measured by appetite questionnaires, a food preference task, saliva
production and food intake
Study design
counterbalanced cross-over within-subject intervention study
Intervention
Participants will participate in one screening session and five test sessions.
In each test session, participants will be exposed to an ambient odor and will
be tested for physiological and behavioural measures that reflect food cue
reactivity.
Study burden and risks
This study is non-therapeutic. Participation with this study is associated with
a negligible burden and risk. Compared to other studies the burden can be
considered as low. The study includes five site visits in a non-satiated state
plus a screening session.
