Adiponectin: Starving for Attention Gregory R. Steinberg, Bruce E. Kemp  Cell Metabolism  Volume 6, Issue 1, Pages 3-4 (July 2007) DOI: 10.1016/j.cmet.2007.06.008 Copyright © 2007 Elsevier Inc. Terms and Conditions

Figure 1 Appetite Control by Adiponectin Fasting triggers increased adiponectin in the cerebrospinal fluid (CSF) and activation of AMPK in the brain, which increases NPY and induces feeding (green arrows). Feeding reduces adiponectin and lowers appetite (red arrows). In obesity, the capacity to lower adiponectin in response to feeding is suppressed, preventing the switching off of appetite (dashed red arrow).
