- no insulin therapy
- no co-morbidities
- stable medication use for the last 6 months
- stable body weight the last 6 months
- no diet in the last 6 months
Exclusion Criteria:

Outcomes
Primary Outcome Measures
whole body insulin sensitivity
Participants underwent a two-step hyperinsulinemic euglycemic clamp to determine insulin sensitivity, expressed as rate of glucose disposal (Rd) in mg/kg/min.
Secondary Outcome Measures
intrahepatocellular lipid content
Liver proton-magnetic resonance spectroscopy was applied to determine liver fat (HCL) in % (relative to the water peak).

5. Study Description
Brief Summary
Thiazoledinediones decrease blood glucose by their insulin-sensitizing properties. Here the investigators examined whether pioglitazone (PIO) improves insulin sensitivity independently of glycemic control and whether adipokines or non-esterfied fatty acids (NEFA) serve as mediators.
