Figure 1

Mean ± SD time-course changes in plasma glucose (A, B) and insulin (C, D), following pre-meal consumption of a WP (red) and PLA preload (black) in lean (A, C) and centrally obese (B, D) males. Pre-meal treatments were administered 10 min before breakfast (t = −10 min), as indicated by the arrow on the figure. The mixed-nutrient meal was served at t = −0min and was to be consumed within 15 min. Time-course glucose data were analysed by a mixed-model ANOVA with repeated measures (time and treatment). Time-course insulin data were analysed by a Friedman’s ranks test with pairwise comparison. Between-group differences in postprandial insulin were assessed by a Kruskal–Wallis H test. *Denotes a within-group treatment effect (i.e., WP vs PLA). #denotes between-group differences (i.e., lean vs centrally obese) during the WP trial. ∇denotes between-group differences during the PLA trial. Statistical significance was accepted as p <0.05.
