Defective medium-chain fatty acid β-oxidation in the liver alters the fat preference and induces hepatic steatosis and glucose intolerance

Medium-chain triglycerides (MCTs) exert antiobesity effects; however, whether these antiobesity effects are observed when the MCT/long-chain triglyceride intake is altered using a high-fat diet (30 kcal% fat) remains unclear. This study found that impaired medium-chain fatty acid metabolism in the liver reduced MCT preference, without altering the total fat intake, resulting in metabolic dysfunction. Therefore, increasing the MCT ratio in dietary fats possibly reduces the risk of obesity.
