About this trial
The purpose of this study is:
1. To explore to what extent insulin sensitivity, energy metabolism and ectopic lipid storage can be improved by bariatric surgery 2. To explore to what extent hepatic and muscular disorders of energy metabolism occur in patients with obesity (degree 2-3) 3. To explore whether the steato liver occurring in patients with obesity (degree 2-3) is associated with the degree of liver inflammation
