- Public TitleExpected satiation.
- Scientific TitleChanges in expected satiation after repeated exposures to low-energy-dense or high-energy-dense foods.
- ACRONYMN/A
- hypothesisWe expect a decrease in the expected satiating capacity of the test food after repeated exposure to the low-energy-dense version of the soup and an increase in expected satiation after the repeated consumption of the high-energy-dense soup.

- Brief summaryRationale: An important underlying determinant in eating behaviour is learned satiation, in which it is assumed that repeated consumption leads to an association between food properties and post-ingestive consequences. However, cognitive factors must not be neglected in food choice and meal size, and expectations on the satiating capacity, i.e. ¡®expected satiation¡¯, may affect portion size selection. A parallel intervention study with two groups: participants will be offered either 1) a low-energy-dense homogeneous soup or 2) a high-energy-dense homogeneous soup. In the study period, soups will be offered in a fixed load on 4 consecutive days (day 1-4) and ad libitum on day 5. Subjects will perform a measurement on expected satiation at baseline and after repeated exposure. In this measurement, participant will be asked to indicate the amount of various comparison foods that will be equally as filling as the soup by means of a photo program on the computer. Learning will be indicated by a shift in expectations relative to day 1. On day 5, we will measure ad libitum intake of the soups to test whether meal size will be different in response to different energy densities of the soup.
