Mean (±SEM) values for plasma active glucagon-like peptide 1 [GLP-1; n = 16 control, n = 19 oligofructose (OFS)] (A), total peptide YY (PYY; n = 16 control, n = 18 OFS) (B), and active ghrelin (n = 16 control, n = 20 OFS) (C) concentrations during a 6-h meal tolerance test as absolute concentrations and as a percentage of baseline. Control initial (□), OFS initial (■), control final (○), and OFS final (●). Repeated-measures ANOVA for absolute concentrations showed a time × diet effect (P = 0.04) and a month × diet effect (P = 0.05) for ghrelin and a month × diet effect for PYY (P = 0.05). Repeated-measures ANOVA showed a time × diet effect (P = 0.017) and a month × diet effect (P = 0.031) for ghrelin expressed as percentage of baseline. *Significant difference between OFS and control at the final test day, P < 0.05; †significant difference within the OFS group between initial and final tests, P < 0.05; ‡significant difference in the control group between initial and final tests, P < 0.05.
