- Resting state brain activity using fMRI [ Time Frame: 35 min ]Functional brain imaging will be employed to assess metabolic gut-brain signaling during a single blind, randomized cross-over design of gastric glucose vs. water infusion.
- Experimental fMRI task [ Time Frame: 20 min ]Participants will be asked to either view food or nonfood images or to down-regulate their emotional response by distracting themselves from the stimuli by solving an arithmetic task.
- Analysis of hormonal satiety signaling [ Time Frame: 30 min before scanning, 30 min after intragastric feeding, 60 min after intragastric feeding ]Blood is collected for the measurement of peripheral ghrelin. In total, three blood samples will be collected.
- Self-report questionnaire regarding eating behavior (Dutch Eating Behavior Questionnaire) [ Time Frame: 30 min ]Psychometric tests will be employed to assess eating behavior and eating disorder psychopathology (using the Dutch Eating Behavior Questionnaire).
