Which scenario represents satiation?

Satiation refers to the state of being satisfied or having one’s appetite fulfilled, leading to a temporary cessation of the desire to eat. In this context, the scenario where Tom refuses food after a large meal clearly illustrates satiation. After consuming a substantial amount of food, his physiological and psychological signals indicate that he has had enough to eat, leading him to decline further food. This response is a direct reflection of satiation, as his body no longer requires additional nutrients or calories at that moment.

The other scenarios do not exemplify this state. For instance, going grocery shopping after not eating all day indicates hunger rather than satiation, since Tom is likely to feel a strong desire for food. Feeling hunger after missing breakfast also highlights a state of needing nourishment, not being satisfied. Eating at a buffet multiple times may demonstrate a lack of satiation, as it suggests that Tom is still seeking food and has not reached the point of being satisfied despite his attempts to eat.
