Acute moderate-intensity exercise does not significantly alter postprandial ghrelin levels in normal-weight subjects, suggesting ghrelin is not the primary driver of exercise-induced appetite suppression.
Don't blame ghrelin for your hunger (or lack thereof) after a moderate workout. Your body uses other signals (PYY, GLP-1) to manage appetite.

No significant effect of exercise was observed on postprandial levels of ghrelin.
