- Target number of participants18
- Interventions: Participants join five sessions during which they sham feed on model foods (x4) and 1 session during which they do not sham feed or eat the gels. The model foods or gels differ in chewing duration and sweetness. During sham feeding and during the control condition blood drawings are taken and subjects are recorded on video to determine the number of chews.
- Primary outcomeThe main parameters of interest are responses of glucose , insulin, PP, ghrelin, CCK-8 and leptin.
- Secondary outcomeThe secondary study parameter is intake in gram during an ad libitum lunch meal.
