Outcome Measures

Primary Outcomes (1)

  • Composite Appetite Sensations Incremental Area Under the Curve

    Incremental area under the curve (iAUC) for composite appetite sensations in response to each product. During each of the Clinical Investigation Days iAUC composite appetite will be measured 180 minutes post intake. The following sensations of appetite will be used in the composite measure: * hunger * fullness * desire to eat * prospective consumption Minimum value 0 Maximum value 100 Higher scores mean worse outcome

    Clinical Investigation Day 1, 2, 3, 4, 5, 6

Secondary Outcomes (12)

  • Leeds Food Preference Questionnaire (LFPQ) Explicit Liking

    Clinical Investigation Day 1, 2, 3, 4, 5, 6

  • Leeds Food Preference Questionnaire (LFPQ) Implicit Wanting

    Clinical Investigation Day 1, 2, 3, 4, 5, 6

  • Leeds Food Preference Questionnaire (LFPQ) Relative preference

    Clinical Investigation Day 1, 2, 3, 4, 5, 6

  • Leeds Food Preference Questionnaire (LFPQ) Explicit wanting

    Clinical Investigation Day 1, 2, 3, 4, 5, 6

  • Control of Eating Questionnaire (CoEQ): Craving Control

    Clinical Investigation Day 1, 2, 3, 4, 5, 6

  • +7 more secondary outcomes

Other Outcomes (39)

  • Body composition: fat mass (kg)

    Clinical Investigation Day 1, 2, 3, 4, 5, 6

  • Body composition: fat-free mass (kg)
