Inclusion Criteria

Dutch women.
Healthy and normal body weight (BMI: 18.5 - 25 kg/m^2).
Between 18 * 35 years old.
Normal sense of smell.

Normal sense of taste and colour blindness will be assessed during the
screening session. However, the goal of these tasks are to distract the
attention from the odour identification test. Therefore, these tasks are not
considered as inclusion criteria for the real aim of the study They will be
added in the files for participants information (E1/E2, E3, F1-PIF) in order to
be consistent with our alternative goal .

In the last test session, participants will be performed a debriefing
questionnaire on aim of the study and awareness of any odour. After subjects
complete the questionnaire, they will be briefed about the actual aim of the
study by the researchers. Subjects are welcomed to ask any further question.

Study & Design

• Study Type: Interventional
• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
<p>The main study parameters are: change in specific appetite for foods congruent<br /><br>vs incongruent with the exposed odour (difference between pre and post odour<br /><br>exposure), and food intake (for congruent vs incongruent foods).</p><br>

Secondary Outcome Measures

Name	Time	Method
<p>Secondary parameters are: food/macronutrient preference (relative preference<br /><br>score), and correlation between self-reported macronutrient preference and<br /><br>actual macronutrient intake.<br /><br><br /><br>In addition, influences of hunger and satiety states on psychometric<br /><br>performance will be explored. </p><br>
