Brain-Gut Cross-Talk in Obesity: Ghrelin and Leptin as the Ultimate Weight Challengers

Ghrelin (hunger) and leptin (satiety) form the core brain-gut axis controlling body weight, with their interactions involving GLP-1, PYY, and hypothalamic circuits — disruption drives obesity.

What This Study Found

Ghrelin-leptin cross-talk through the brain-gut axis constitutes the core energy balance system, integrating with GLP-1, PYY, NPY, and melanocortin circuits — obesity results from disruption of this integrated network.
