you can starve, or get really bad hunger pains.
The physiological condition that causes you to feel hunger is the release of a hormone called ghrelin in your body, which signals to your brain that you need to eat.

Least descriptive of the hypothalamus would be "responsible for cognitive functions" as the hypothalamus is primarily involved in regulating various physiological processes such as body temperature, hunger, and thirst, rather than cognitive functions.
The Cannon-Washburn Hunger Study, conducted in the early 20th century by physiologist Walter Cannon and his student, A. L. Washburn, aimed to investigate the physiological basis of hunger. They used a device called a "hunger pang" to measure stomach contractions in participants while also assessing their subjective feelings of hunger. The study provided insights into the relationship between physiological signals and the sensation of hunger, supporting the idea that physical states within the body contribute to the experience of hunger. This research laid important groundwork for understanding the interplay between biology and appetite regulation.
The sensation of hunger is primarily triggered by hormonal and neural signals in response to energy needs. Key hormones, such as ghrelin, are released from the stomach when it is empty, signaling the brain to initiate the feeling of hunger. Additionally, low blood glucose levels can activate the hypothalamus, further stimulating appetite. Together, these physiological responses prompt the need for food intake.
