Hormonal
Hypothalamic AMPK and mTOR act as fuel sensors that integrate energy status signals to regulate food intake and energy expenditure.
Your brain uses molecular sensors (AMPK and mTOR) to detect energy availability. When these sensors are activated or inhibited by nutrients or hormones, they adjust your hunger and energy expenditure.
GoodSupportsHIGH confidence
Two protein kinases, AMP-activated protein kinase (AMPK) (77) and mTOR (3), have recently been found to play a crucial role in integrating signals of energy status in the hypothalamus.

More from this paper
- 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
- Central administration of GLP-1 reduces food intake and improves glucose tolerance by acting on hypothalamic and hindbrain receptors, independent of peripheral effects.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
