STOIC Posted February 2, 2006 Viking, Leptin is an adipocyte hormone that we all humans have.Leptin signals hypothalamus how much fat is stored, regulating hunger and food intake.When people are starved the adipose level goes down this triggers the going down of Leptin and hence this leads to diminishing of the immune system too.Obesity involves increase in both size and numbers of adipocytes.As stored fat increases, secretion of Leptin increases.Leptin usually acts on arcute nucleus of the hypothalamus to suppress neuropeptide Y which increases the feeling of hunger.There are neurotransmitters too that promote overeating, example is endomorphin.If you want to know whether you are obessed, divide your weight(in Kg) by your height squared(in meters).If your calculation is above thirty then you are obessed.
