from what i vaguely recall, a body starts releasing insulin when it expects incoming sugar because if it waits until the sugar hits the bloodstream, it has to dump a bunch at once, which is a strain, so it uses environmental cues like the taste (or even smell?) of something sweet. if you keep tricking your body by tasting something sweet, have it start to release insulin, and then have that insulin go unused, it may start to ignore that signal.
