There is increasing evidence that dairy calcium may play a role in body weight regulation. A potential mechanism has been postulated to explain a possible role of calcium in body weight control, and yet it remains unclear whether there is a weight-loss effect of calcium or diary. The purpose of this study was to investigate the effect of regular exercise and/or dairy consumption on acylated-ghrelin(AG), peptide YY(PYY) and subjective appetitive ratings in university male students. Subjects were assigned into 4 groups according to their exercise and dairy consumption habits. AG, PYY, and insulin were assessed at fasting state and 60 min after consumption of standard test meal. The statistical analysis was evaluated by ANOVA for reapeated measures. Exercise groups showed lower blood glucose level and higher postprandial triacylglycerol level than non-exercise groups(p<.05). Postprandial insulin elevation was lowered in exercise groups than non-exercise groups. AG was decreased in exercise and dairy consumption group, and PYY was increased in non-exercise groups after meal(p<.05). For subjective ratings, postprandial hunger level was decreased in exercise and dairy consumption group(p<.05). Desire to eat was decreased in exercise groups after meal(p<.05). Our finding suggests that chronic exercise and dairy consumption reduces serum acylated ghrelin and subjective hunger level, which is related with postprandial anorexia.
