Serum insulin and plasma glucagon profile after meals differing in glycemic index and meal size. Values are medianand 75th percentile. (∙) high glycemic index; (∘) low glycemic index; (—) large meal size; (----) small meal size. Differences in serum glucose, insulin, FFA and plasma glucagon concentrations were analyzed by Friedman's test and two-tailed Wilcoxon ranked post hoc test. Letters indicate significant difference (p < 0.05) between medians as follows: a, 
vs 
; b, 
vs 
; c, vs ; d, vs ; e, vs ; f, vs
