Brief 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.

Study Arms (2)
Metyrapone And Hydrocortisone
EXPERIMENTALDuring one of the study periods, subjects receive hydrocortisone 19.9 mg/d day 1 to day 6 and 12 mg/d on day 7 subcutaneously via a pump in a pulsed fashion (eight times/day) and metyrapone per os (starting with a dose of 750 mg/d, then the dose will be increased on day 3, where 2500mg/d is achieved and reduced on day 7 to 750mg).
Placebo
PLACEBO COMPARATORDuring the other study period, subjects receive placebo (0,9% NaCl solution) the same dose of placebo instead of hydrocortisone subcutaneously via a pump in a pulsed fashion and the same dose of placebo tablets p.o instead of metyrapone.
Interventions
Drug: Metyrapone 250 mg Oral Tablets During one phase of the study: Metyrapone (pills of 250mg) on full stomach: Day 1 0-1-2, day 2 1-2-2, day 3 3-3-4 day 4 3-3-4 day 5 3-3-4 day 6 3-3-4 day 7 3-0-0 Drug: Hydrocortisone 19,9mg/12mg s.c., pulsatile with a flow rate of 10μl/s Hydrocortisone will be delivered subcutaneously via a pump in a pulsed fashion with a flow rate of 10μl/s from day 1 to day 6 in a total daily dose of 19.9mg and 12mg on day 7
Drug: Placebo 250 mg Tablets During another phase of the study: identical looking placebo pills starting Day 1 During one phase of the study: Metyrapone (pills of 250mg) on full stomach: Day 1 0-1-2, day 2 1-2-2, day 3 3-3-4 day 4 3-3-4 day 5 3-3-4 day 6 3-3-4 day 7 3-0-0 Drug: Placebo (0,9% NaCl solution) Placebo (0,9% NaCl solution) 19.9 mg/d subcutaneously via a pump in a pulsed fashion with a flow rate of 10μl/s from day 1 to day 6 and 12mg on day 7
