Understanding Hunger Mechanisms

Very Hard Unit 7: Motivation, Emotion, Personality Hunger And Eating

The regulation of hunger and eating is a complex process that involves physiological, psychological, and environmental factors. One notable theory in this field is the Dual Center Theory, which posits that different areas in the brain are responsible for stimulating and inhibiting hunger. The hypothalamus plays a central role in this regulation. Additionally, factors such as blood glucose levels and hormones like ghrelin and leptin also contribute to hunger signals.

Considering these elements, which of the following statements most accurately reflects an understanding of the mechanisms behind hunger and eating behaviors?

Leptin is released from adipose tissue and signals hunger by acting on the hypothalamus.

Ghrelin levels increase before meals and are thought to stimulate appetite.

The ventromedial hypothalamus is involved in stimulating hunger and eating.

Insulin functions solely to increase appetite by acting on the brain.

The lateral hypothalamus inhibits hunger signals when energy levels are low.
