Energy balance

GDF15 maintains energy expenditure and promotes weight loss through a GFRAL-dependent signaling axis that activates beta-adrenergic receptors in skeletal muscle, increasing fatty acid oxidation and calcium futile cycling.

The weight loss benefits of GDF15 rely on a specific biological pathway involving the GFRAL receptor and beta-adrenergic signaling in muscles. If this pathway is blocked or missing, the energy expenditure benefits are lost.
