Obesity-associated adipose tissue inflammation, driven by macrophage infiltration and cytokine release, directly blunts insulin signaling and contributes to systemic insulin resistance.
In obesity, fat tissue isn't just storage; it becomes inflamed, recruiting immune cells that block insulin's ability to work. Reducing this inflammation is key to improving metabolic health.
GoodSupportsHIGH confidence
The infiltration of macrophages per se can trigger increased local and systemic inflammation, which is associated with decreased insulin sensitivity... reduction of local inflammation in adipose tissue... is invariably associated with improvements in local and systemic insulin sensitivity.
Why this rating
Based on a review of multiple studies including transgenic models and human tissue analysis.

- Ectopic lipid accumulation in non-adipose tissues (liver, muscle) causes insulin resistance primarily through diacylglycerol and ceramide signaling, not triglyceride storage itself.Strong
- Adiponectin overexpression in adipose tissue improves metabolic profile and insulin sensitivity by promoting lipid storage in subcutaneous fat and reducing ectopic lipid accumulation.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
