Importance of the GH/IGF-1 Axis for Human Substrate and Energy Metabolism During Calorie Restriction

Summary

This study will investigate whether growth hormone is modulated by the enzyme SIRT1 and by that is stimulating lipolysis on expense of IGF-I production. This is done in 10 healthy men on calorie restriction on 4 study days with fat and skeletal muscle biopsies.
