Abstract
There is good reason to believe that regular moderate alcohol consumption promotes insulin sensitivity of skeletal muscle; conceivably, this benefits the protective effects of moderate drinking on vascular health and risk for obesity and diabetes. The mechanism responsible for alcohol's insulin-sensitizing activity remains obscure. As a working hypothesis, it is proposed that metabolism of acetate in peripheral tissues generates sufficient levels of AMP to temporarily stimulate the AMP-activated protein kinase, which in turn induces the synthesis of certain long-lived proteins that act to boost insulin sensitivity and possibly aid the efficiency of fat oxidation as well.
