Obesity-induced chronic inflammation in adipose tissue, driven by M1 macrophage infiltration and TNFα secretion, directly causes systemic insulin resistance.
In obesity, fat tissue becomes inflamed, releasing chemicals like TNFα that block insulin action. This inflammation is a key driver of insulin resistance, not just excess calories. Strategies that reduce this specific inflammatory response may help improve metabolic health.
GoodSupportsHIGH confidence
It has been demonstrated in rodents and humans that chronic inflammation characterized by macrophage infiltration occurs mainly in adipose tissue or liver during obesity, in which activation of immune cells is closely associated with insulin sensitivity.
Why this rating
Based on a comprehensive review of multiple human and rodent studies establishing a strong causal link.

- M2 macrophages sustain insulin sensitivity by secreting IL-4 and IL-10, whereas M1 macrophages induce insulin resistance through proinflammatory cytokines like TNFα.Strong
- MCP-1 (CCL2) secretion from hypertrophied adipocytes recruits monocytes to adipose tissue, leading to M1 macrophage infiltration and insulin resistance.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
