Mean ghrelin levels (pg/ml) in 10 normal weight (solid line) versus 13 severely obese (broken line) women. The ghrelin response postprandially showed a trend for a difference between groups (p = 0.06). Averaged over time, the normal weight group had significantly higher postprandial ghrelin levels than the severely obese group (p = 0.004). Ghrelin levels were significantly higher * (p ≤ 0.05) in normal weight women at baseline (p = 0.001), 15 (p = 0.001), 60 (p = 0.032) and 120 (p = 0.044) minutes postprandially.
