To this end, type 2 diabetic patients and body mass index (BMI)-matched controls will be included in a blinded cross-over design, in which subjects will receive a lipid lowering agent (Acipimox) or placebo for 2 weeks in random order. During treatment, diabetes medication will be stopped. Baseline measurements will be performed prior to the study and after each treatment to assess cardiac and muscular lipid accumulation, cardiac function, mitochondrial function and insulin sensitivity.
