PYY is secreted postprandially from the endocrine L-cells of the gastrointestinal tract. PYY3–36, the major circulating form of PYY, reduces food intake in humans and rodents via high affinity binding to the auto-inhibitory NPY receptor, Y2R, within the hypothalamic arcuate nucleus.Aims: To investigate (1) the effects of length of fast on the anorexigenic actions of PYY3–36; (2) the effects of early light phase administrat...
