The increased body and muscle fat are associated with insulin resistance and low-grade chronic inflammation, with an increase in many specific and unspecific inflammatory parameters, like C reactive protein (CRP), fibrinogen, interleukin-6 (IL-6), and tumor-necrosis-factor alpha (TNF-α), which lead to the decrease in both muscle mass and strength, and to bone loss (35) (Figure 2). Here, IL6 is linked to Insulin resistance.
