The results of this study will be published in a high-impact international research journal with a focus on sensory science and nutrition.

•Healthy and normal body weight (BMI: 18.5 - 25 kg/m2).
•Females between 18 – 35 years old.
•Normal sense of smell, scoring = 12 on the Sniffin’ Sticks 16 items odour identification test 34.
•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 are included in the participants information files (E1/E2, E3, F1-PIF) in order to be consistent with our alternative goal.

•Restrained eaters, assess by DEBQ by restraint score > 3.4 32. We are interested in normal eating behaviour; subjects have to eat ad libitum, without self-restriction.
•Smokers. Smoking could affect olfactory function.
•Any food restriction such as vegetarian, vegan, etc. Due to the variety of odours and food products involved in this study (e.g. products high in carbohydrates: bread, corn, pasta; high in protein are mainly from animal sources; high in fat: avocado, bacon, etc.).
•Any allergy, intolerance or oversensitivity to food used in this study (food that resemble the used odours and food that will be used in the ad libitum lunch).
•Dislike of food products used in the study (Liking <40 mm VAS). Liking could affect the appetite or willingness to eat the food products.
•Use of medication other than paracetamol and hormonal contraceptives.
•Pregnant/have the intention to become pregnant during the experiment/are currently breastfeeding. Hormonal status could affect olfactory function.
•Reported weight loss or weigh gain of more than 5 kg or following a special diet in the two months prior the study.
•Staff member of the Division of Human Nutrition and Health at Wageningen University, or students currently performing a MSc thesis at the Division of Nutrition and Health.
•Participation in other medical studies.
•Participation in the previous part of the study (part A- STER study 1).
