Acute Consequences of Glucocorticoid Secretion in Overweight and Obese Individuals During Maximum Calorie Intake
Sponsor: Eleonora Seelig
Summary
The investigator aim to understand whether food-induced glucocorticoids influence fat mass in overweight and obese people. In a randomized, cross-over study, 23 overweight and obese volunteers will receive a block and replace therapy that mimics physiological glucocorticoid (GC) rhythm (metyrapone plus hydrocortisone) or placebo. Participants will undergo two identical overfeeding periods with each treatment. With the block and replace therapy food-induced GC peak will be suppressed. Metabolic and immunological parameters will be compared to reveal the effects of GCs during excessive overfeeding, particularly to understand changes in body fat.
