Brief Summary:
The focus of this cross-sectional study is to determine the effects of tissue-specific adipose tissue or muscle vs global combined insulin resistance IR on hepatic triglyceride biosynthesis in humans and to determine differential effects of an acute exercise intervention on hepatic triglyceride biosynthesis in these groups
Detailed Description:
Hypothesis Patients who primarily have muscle IR will have a greater percentage of lipids derived from de novo lipogenesis DNL than patients with combined muscle and adipose IR and these subjects will respond more robustly to the effects of premeal exercise
With this study the investigators will demonstrate that the mechanisms that drive triglyceride overproduction in insulin-resistant humans are dependent on which tissues are insulin resistant To this end investigators will determine whether subjects with muscle insulin resistance and adipose tissue insulin resistance utilize different mechanisms of triglyceride biosynthesis to assemble hepatic very low density lipoprotein VLDL as compared with individuals with muscle insulin resistance but relative adipose tissue insulin sensitivity Additionally investigators will see if adipose tissue insulin sensitivity predicts exercise responsiveness of hepatic triglyceride production
Main study parametersendpoints Difference in DNL between subjects with global vs muscle-only insulin resistance as well as the differential effects of premeal exercise on DNL in these groups
