The Acute Response of Glucocorticoids Upon Food Intake

Detailed Summary

Investigators suggest that in lean subjects cortisol increases in response to overfeeding and that this increase is blunted in obese subjects. A group of 18 male healthy lean subjects and another group of 18 male healthy obese subjects will undergo a high-calorie meal test. Prior to the meal intake, an indirect calorimetry, bioelectrical impedance, heart rate variability, a fasting blood sample and a perceived stress questionnaire will be assessed. After intake of the study meal, blood tests will be performed in order to measure the secretion of cortisol, glucose and lipid metabolism and inflammatory markers. Indirect calorimetry will be assessed again 60 and 180 minutes after the meal intake.
