Arms	Assigned Interventions
Experimental: a the aim of the present study is to characterize the treatment related changes in insulin sensitivity, substrate metabolism and intrahepatic-intramyocellular lipids in 12 adult patients, recently diagnosed with growth hormone deficiency	Drug: growth hormone (genotropin) Dosage regulation will follow the local recommendations of GHD treatment
No Intervention: Control Intramyocellular, intrahepatic and intraabdominal lipid content, lean body mass and body fat percentage, are assessed in ten healthy controls matched on age, gender and BMI.
