What does it mean to be "hungry"?

Being "hungry" primarily refers to the physiological sensation that signals the need for food. This feeling arises when the body requires energy and nutrients, which can occur due to various factors, such as the time since the last meal or the body's energy expenditure. When someone describes themselves as hungry, they are communicating their body's demand for sustenance to maintain health and vitality.

The other options do not accurately capture the essence of hunger. While thirst is a legitimate issue, it relates to the need for drink rather than food. The descriptions of food as "not nice to eat" or "very tasty" are subjective opinions about the quality or appeal of food, but they do not pertain to hunger itself. Hunger is fundamentally about the body's need for food, making the first choice the most accurate definition.
