WebDec 1, 2006 · Previous studies suggest that insulin can inhibit hepatic glucose production by both direct and indirect actions. The indirect effects include inhibition of glucagon secretion, reduction in plasma nonesterified fatty acid levels, reduction of the amount of gluconeogenic precursor supplied to the liver, and change in neural input to the liver. WebLipolysis is a process of degradation fat to fatty acid and triacylglycerol. Insulin decreases the rate of lipolysis and leads to fat storage in adipose tissue and hence lowers the …
