Dietary protein source dictates the impact of obesogenic diets on hepatic steatosis and insulin resistance via carnitine-dependent regulation of acetyl-CoA carboxylase
This study reveals that dietary protein sources (pork and soy) exacerbate obesity and hepatic insulin resistance in obesogenic conditions by elevating carnitine levels, which downregulate ACC2 and alter mitochondrial lipid handling, whereas casein protein does not produce these adverse effects.
