← Human Body & HealthA patient maintains stable weight despite erratic eating habits. Which mechanism explains how appetite regulation compensates in this scenario?
A)Increased glucagon secretion offsets overeating
B)Ghrelin and leptin exhibit opposing oscillations✓
C)Elevated insulin desensitizes hypothalamic neurons
D)Cortisol dysregulation overrides satiety signals
💡 Explanation
Ghrelin, signaling hunger, and leptin, signaling satiety, oscillate out of phase. Erratic eating leads to compensatory ghrelin and leptin fluctuations. Therefore, balanced appetite regulation persists because these hormones counterbalance each other, rather than glucagon, insulin, or cortisol fully overriding appetite.
