GIPR antagonism reduces body weight in preclinical models by restoring leptin sensitivity, thereby reducing appetite.
Blocking GIP receptors can help obese individuals lose weight by making their bodies more sensitive to leptin, the hormone that signals fullness. This is currently only proven in animal models.
ModerateSupportsMEDIUM confidence
Kaneko et al, when investigating the effects of central infusion of Gipg013, proposed that the reason for the observed reduction in appetite was an improvement in leptin sensitivity.
Why this rating
Supported by specific preclinical studies, but human translation is unclear.

More from this paper
- GIPR agonism in humans may not provide weight loss benefits and can negate the appetite-suppressing effects of GLP-1.Good
- Combining GIPR agonism or antagonism with GLP-1 R agonism produces synergistic weight loss in preclinical models, whereas GIPR signaling is not required for this synergy in humans.Moderate

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
