In this article there is a graph showing sharp peaks of ghrelin at mealtimes and a rapid drop-off after the meal is eaten. There is also a peak during the night, but there is no meal responsible for the drop-off. Does the research indicate what happens to the ghrelin level during the day when a meal is missed?
