Subjective appetite profiles
Délai: 8 h (-30, 0, 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330, 360, 390, 420, 450, 480)
|
Subjective feelings of appetite (satiety, hunger and desire to eat) are assessed by visual analogue scale (VAS) (in total 18 measurements).
|
8 h (-30, 0, 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330, 360, 390, 420, 450, 480)

|
Glucose, insulin, glucagon, glucagon-like peptide-1 (GLP-1), glucose-dependent insulino-tropic polypeptide (GIP), peptide YY (PYY), cholecystokinin (CCK), leptin and ghrelin are measured in plasma samples.
|
8 h (-15, 15, 35, 65, 95, 125, 185, 230, 275, 305, 365, 470)

Metabolic profiles
Délai: 8 h (-15, 15, 35, 65, 95, 125, 185, 230, 275, 305, 365, 470)
|
The flux of nutrients is measured in plasma samples.

Products from bacterial fermentation of dietary fibre
Délai: 8 h (-15, 15, 35, 65, 95, 125, 185, 230, 275, 305, 365, 470)

Ad libitum food intake
Délai: 8 h after breakfast (480 min)
|
Energy intakes will be assessed from the ad libitum dinner in order to validate subjective appetite measurements.
|
8 h after breakfast (480 min)
