Mean insulin levels (μU/ml) in 10 normal weight (solid line) versus 13 severely obese (broken line) participants. The postprandial response was not significantly different between groups (p = 0.260), but averaged over time, insulin levels showed a trend to be higher in the severely obese group than in the normal weight group (p = 0.064). Insulin levels were significantly higher * (p < 0.05) in the severely obese group only at 15 minutes postprandially (p = 0.025).
