Liver enzyme marker. Traditional "normal" ranges miss 57% of NAFLD cases. Optimal thresholds are lower.
Traditional "normal" ALT ranges (<40 U/L) miss 57% of NAFLD (non-alcoholic fatty liver disease) cases. Research suggests optimal thresholds are <25 U/L for men and <19 U/L for women.
ALT (alanine aminotransferase, also known as SGPT) is a liver enzyme. When liver cells are damaged, ALT is released into the bloodstream.
Elevated ALT is often an early sign of fatty liver, which may precede a diagnosis of insulin resistance or type 2 diabetes by years.
Choline deficiency (lack of eggs, liver consumption) can also cause elevated ALT, especially on low-carb diets.
