Answer 1

The right answer is ghrelin levels are relatively low.​

Ghrelin is a hormone secreted by the cells of the stomach, ghrelin triggers the sensation of hunger. The release of ghrelin is done when the body needs a new supply of energy and therefore to feed. The rate of ghrelin decreases following the meal: the hunger disappears.

This hormone is the subject of many studies: inhibiting its action may help to fight against obesity. At least for obesity due mainly to overeating.
