Primary Outcome Measures:
  • food intake [ Time Frame: on testday 0 and 13 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • appetite profile ratings [ Time Frame: on test day 0, 8 and 13 (at 16 time points) ] [ Designated as safety issue: No ]
  • satiety hormones (GLP-1 and PYY) [ Time Frame: on test day 0 and 13 (at 9 time points ] [ Designated as safety issue: No ]

Enrollment: 30
Study Start Date: January 2009
Study Completion Date: February 2010
Primary Completion Date: February 2010 (Final data collection date for primary outcome measure)
Intervention Details:
    Dietary Supplement: inulin
    10gram/day inulin for 13-day treatment
    Other Name: oligofructose
    Dietary Supplement: inulin
    16gram/day inulin for 13-day treatment
    Other Name: oligofructose
    Dietary Supplement: placebo
    16gram/day maltodextrin (placebo) for 13-day treatment
    Other Name: maltodextrin
Detailed Description:

Based upon a slower digestion and the fermentation in the intestinal tract, food containing soluble dietary fibres, such as inulin, is hypothesized to be more satiating, and to limit energy intake, in humans. Does supplementation of inulin (at 2 dosages) versus placebo over 13 consecutive days in normal to overweight men and women, lead to an increase in satiety, a reduction in food intake and stronger postprandial increases in GLP-1 and PYY?
