Butyrate enhances insulin sensitivity by boosting mitochondrial activity and preventing metabolic endotoxemia. This short-chain fatty acid (SCFA) also improves intestinal barrier function, offering protection against diet-induced obesity without reducing food intake.
Propionate inhibits cholesterol synthesis. It counteracts the cholesterol-increasing effects of acetate. This action may contribute to improved metabolic health. It may also enhance insulin sensitivity.
Butyrate and propionate both stimulate the production of anorexigenic gut hormones. They also increase leptin synthesis. These hormonal changes can have a positive impact on weight regulation. Additionally, they can improve insulin sensitivity.
