Answer 1

The correct answer is: low glucose levels.

Blood levels of nutrients such as glucose, amino acids, and fatty acids provide an information to the brain about the food- energy intake. Besides those nutrients, hormones play an important role in the regulation of hunger. For example, Glucagon, ghrelin (stomach) and epinephrine are hunger stimulants.  There are also neural signals and psychological factors that regulate hunger.
