Hormonal
Central administration of GLP-1 reduces food intake and improves glucose tolerance by acting on hypothalamic and hindbrain receptors, independent of peripheral effects.
GLP-1 is not just a gut hormone; it signals the brain to reduce food intake and improve glucose control. This dual action makes it effective for treating obesity and diabetes.
GoodSupportsHIGH confidence
Turton et al. (43) were the first to demonstrate that intracerebro-ventricular (ICV) administration of GLP-1 in rats suppresses food intake... Many subsequent studies have confirmed the ability of centrally administered GLP-1 to reduce food intake.
Why this rating
Supported by multiple cited studies in rats and humans.

- The central nervous system (CNS) integrates peripheral adiposity signals (insulin and leptin) and gastrointestinal signals (GLP-1) to regulate both energy balance and glucose homeostasis through overlapping hypothalamic mechanisms.Good
- Hypothalamic AMPK and mTOR act as fuel sensors that integrate energy status signals to regulate food intake and energy expenditure.Good

- 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
