Which of the following statements represents a function of the hormone ghrelin?

Ghrelin is often referred to as the "hunger hormone" because it plays a critical role in stimulating appetite. When the stomach is empty, ghrelin levels increase, signaling the brain to create the sensation of hunger. This hormone not only prompts food intake but also influences meal timing and the promotion of energy balance. Higher levels of ghrelin lead to increased food cravings and the desire to eat, making the first statement about its function accurate. Understanding ghrelin's role in hunger regulation is essential, particularly for nutrition coaches who need to guide clients in recognizing hunger and satiety cues while managing dietary habits.
