Remembered Meal Satisfaction, Satiety and Later Snack Food Intake

Remembered Meal Satisfaction, Satiety and Later Snack Food Intake: A Laboratory Study

This study examined whether remembered meal satisfaction (encompassing memory for meal liking and satiety) can be manipulated in the laboratory and whether this influences later food intake.

Study Overview

• Status: Completed
• Conditions: Overweight and Obesity
• Intervention / Treatment: Behavioral: Satisfying rehearsal task; Behavioral: Dissatisfying rehearsal task; Behavioral: Neutral rehearsal

Detailed Description

This study examined whether remembered meal satisfaction (encompassing memory for meal liking and satiety) can be manipulated in the laboratory and whether this influences later food intake. In a between-subjects design participants consumed a fixed lunch and then rehearsed the satisfying or dissatisfying aspects of the meal, or a neutral experience (control), in order to manipulate memory for meal satisfaction. Three hours later, in a second visit to the laboratory, participants completed a bogus taste-test to measure food intake and meal memory measures.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: Satisfying rehearsal; Participants completed the satisfying rehearsal task where they rehearsed the satisfying aspects of the lunchtime meal.	Behavioral: Satisfying rehearsal task; Participants rehearsed satisfying aspects of the lunchtime meal they just ate.
EXPERIMENTAL: Dissatisfying rehearsal; Participants completed the dissatisfying rehearsal task where they rehearsed the dissatisfying aspects of the lunchtime meal.	Behavioral: Dissatisfying rehearsal task; Participants rehearsed dissatisfying aspects of the lunchtime meal they just ate.
ACTIVE_COMPARATOR: Neutral rehearsal; Participants completed the neutral rehearsal task where they rehearsed their journey to campus that day.	Behavioral: Neutral rehearsal; Participants rehearsed their journey to campus that day.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Ad libitum snack intake	Energy intake (kcal) measured from a bogus taste-test task. Lower intake in those in the satisfying rehearsal condition compared to the control condition and greater intake in the dissatisfying rehearsal condition compared to the control condition were expected.	Measured during second visit that took place 3 hours after the baseline visit

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Memory for general satisfaction	Memory for general satisfaction with the lunchtime meal was measured via five questions: 'Overall, how satisfying did you find the lunchtime meal?', 'Overall, how dissatisfying did you find the lunchtime meal?', 'I liked the lunchtime meal', 'How satisfied were you with the taste of the lunchtime meal?' and 'How dissatisfied were you with the taste of the lunchtime meal?'. Responses were measured using 100-point visual analogue scales with anchors 'not at all' and 'extremely' (0-100). A higher score in those in the satisfying rehearsal condition compared to the control condition and a lower score in the dissatisfying rehearsal condition compared to the control condition were expected.	Measured during second visit that took place 3 hours after the baseline visit
Memory for satisfaction with meal satiety	Memory for general satisfaction with the lunchtime meal was measured via two questions: 'How satisfied were you with how filling the lunchtime meal was?' and 'How dissatisfied were you with how filling the lunchtime meal was?'. Responses were measured using 100-point visual analogue scales with anchors 'not at all' and 'extremely' (0-100). A higher score in those in the satisfying rehearsal condition compared to the control condition and a lower score in the dissatisfying rehearsal condition compared to the control condition were expected.	Measured during second visit that took place 3 hours after the baseline visit

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Hunger before lunch	Hunger before lunch was measured via a single question asking 'How hungry do you feel right now?'. Responses were measured via a 100-point visual analogue scale with anchors 'not at all' and 'extremely'. No directional hypothesis was made for this outcome.	Measured before lunch (during baseline visit)
Hunger after lunch	Hunger before lunch was measured via a single question asking 'How hungry do you feel right now?'. Responses were measured via a 100-point visual analogue scale with anchors 'not at all' and 'extremely'. No directional hypothesis was made for this outcome.	Measured after lunch (during baseline visit)
Hunger before the bogus taste-test	Hunger before lunch was measured via a single question asking 'How hungry do you feel right now?'. Responses were measured via a 100-point visual analogue scale with anchors 'not at all' and 'extremely'. No directional hypothesis was made for this outcome.	Measured before the bogus taste-test (in second visit that took place 3 hours after the baseline visit)
Hunger after the bogus taste-test	Hunger before lunch was measured via a single question asking 'How hungry do you feel right now?'. Responses were measured via a 100-point visual analogue scale with anchors 'not at all' and 'extremely'. No directional hypothesis was made for this outcome.	Measured after the bogus taste-test (in second visit that took place 3 hours after the baseline visit)
