Elevated alanine aminotransferase (ALT) levels in nondiabetic individuals are associated with decreased hepatic insulin sensitivity and predict the future development of type 2 diabetes, independent of obesity and whole-body insulin resistance.
If you have elevated ALT, even within the standard 'normal' lab range, it may signal reduced liver insulin sensitivity and a higher risk of developing type 2 diabetes. This is particularly relevant if you have high body fat. Focus on improving hepatic insulin sensitivity through weight management and metabolic health, as ALT serves as an early warning marker independent of whole-body insulin resistance.
Higher ALT concentrations were cross-sectionally associated with obesity and whole-body and hepatic insulin resistance and prospectively associated with a decline in hepatic insulin sensitivity and the development of type 2 diabetes.
Why this rating
Prospective longitudinal study with rigorous metabolic clamping (gold standard for insulin sensitivity) and adjustment for confounders.

- 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
