Insulin resistance is strongly associated with intestinal-derived [[Apolipoprotein B|apoB-48]] production rate in insulin-resistant subjects and type 2 diabetics. Insulin resistance often is found in people with visceral adiposity, hypertension, hyperglycemia, and [[dyslipidemia]] involving elevated triglycerides, small dense [[low-density lipoprotein]] (sdLDL) particles, and decreased [[high-density lipoprotein]] (HDL) cholesterol levels. With respect to visceral adiposity, a great deal of evidence suggests two strong links with insulin resistance. First, unlike subcutaneous adipose tissue, visceral adipose cells produce significant amounts of proinflammatory [[cytokines]] such as tumor necrosis factor-alpha ([[TNF-a]]), and [[Interleukins]]-1 and −6, etc. In numerous experimental models, these proinflammatory cytokines disrupt normal insulin action in fat and muscle cells and may be a major factor in causing the whole-body insulin resistance observed in patients with visceral adiposity. Much of the attention on production of proinflammatory cytokines has focused on the IKK-beta/[[NF-kappa-B]] pathway, a protein network that enhances transcription of inflammatory markers and mediators that may cause insulin resistance. Second, visceral adiposity is related to an accumulation of fat in the liver, a condition known as [[non-alcoholic fatty liver disease]] (NAFLD). The result of NAFLD is an excessive release of free fatty acids into the bloodstream (due to increased lipolysis), and an increase in hepatic breakdown of glycogen stores into glucose ([[glycogenolysis]]), both of which have the effect of exacerbating peripheral insulin resistance and increasing the likelihood of [[T2DM|Type 2 diabetes mellitus]].
