Satiation is the process that ends an eating episode. It controls the meal size and duration.Satiety, on the other hand, is a state of non-hunger and controls subsequent hunger and food intake.
In my searching, I came across the above definition satiation. OK. It makes no sence to me. I have never felt anything but gluttoney, a desire for more. Do "normal" people actually feel satiation, or is this just another concept? I need to stop after I finish my plate. I do not feel what is described as satiation.
