Central GIP receptor (GIPR) agonism decreases body weight and food intake in diet-induced obese mice by activating GABAergic neurons in the area postrema, a mechanism that is independent of hypothalamic GIPR signaling.

Newer weight-loss medications that combine GLP-1 and GIP (like tirzepatide) work partly by activating GIP receptors in your brain's satiety centers. This helps reduce food intake. While GIP was once thought to only help with insulin, its role in the brain is now recognized as beneficial for weight loss.

long-acting GIPR agonists decrease body weight and food intake in DIO mice when given directly into the lateral ventricle of the brain [55]. ... these effects vanish in mice with loss of Gipr in either the CNS [55] or more specifically in gamma-aminobutyric acid (GABAergic) neurons [56]. ... GIPR agonism decreasing food intake via activation of GABAergic neurons to decrease food intake [56].

Why this rating

Strong preclinical evidence in rodents with specific neuronal deletions; human translation is noted as uncertain.
