Outcome measures
Primary outcome
Our main outcome measurement is the difference in energy intake (kJ) during an
ad lib test meal after 24h of a sweet diet, a savoury diet, and a control diet.
Secondary outcome
• To assess the effect of a sweet diet, a savoury diet, and a control diet on
subjective ratings of appetite using a VAS;
• To assess the effect of a 24h sweet diet, a savoury diet, and a control diet
on different aspects of on different aspects of food liking and wanting
measured with an Food Preference Questionnaire.
• To assess the effect of a 24h sweet diet, a savoury diet, and a control diet
on cognitive associations of towards different food categories using a Sorting
Paired Features (SPF) task.
Background summary
Sensory properties of food play an important role in food selection and
intake. Within our food range, products containing high protein levels are in
general more savoury, while products containing carbohydrates are generally
more sweet. Protein has been found to be the more satiating macronutrient. The
role of sensory signals in the satiating effects of protein, however, requires
further clarification.
Study objective
To determine the effect of sensory signals on satiety and food preferences.
Study design
The study will consists of three test days, which will be separated by 1 week.
These test days involve consumption of pre-determined iso-caloric diets
consisting of only sweet products (sweet diet), only savoury products (savoury
diet) or a combination of sweet and savoury products (control diet), using a
randomized crossover design. Afterward energy intake of an ad libitum test meal
is measured. In addition, during the test days, sensations of appetite and
several measures of food preferences will be assessed.
Intervention
Consumption of pre-determined iso-caloric diets consisting of only sweet
products (sweet diet), only savoury products (savoury diet) or a combination of
sweet and savoury products (control diet)
Study burden and risks
The study is non-therapeutic to the participants. The risk associated with
participation is negligible and the burden can be considered as low. No
invasive measurements are present.
