Elevated plasma levels of specific ceramide subspecies (C18:0, C20:0, C24:1, C24:0) are associated with increased severity of insulin resistance in obese subjects with type 2 diabetes.
If you have type 2 diabetes, your body's fat metabolism produces specific lipids (ceramides) that interfere with how your cells respond to insulin. Higher levels of these lipids in your blood are linked to worse insulin resistance. While this paper doesn't prescribe a treatment, it highlights that managing lipid metabolism and inflammation is key to improving insulin sensitivity.
Insulin sensitivity (mg · kg−1 · min−1) was inversely correlated with C18:0 (−0.58, P < 0.003), C20:0 (−0.52, P < 0.008), C24:1 (−0.51, P < 0.009), C24:0 (−0.49, P < 0.01), and total ceramide (−0.58, P < 0.003) concentrations.
Why this rating
Observational study with rigorous measurement (hyperinsulinemic-euglycemic clamp) but limited sample size (n=27) and cross-sectional design.

- 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
