Previous studies have shown that carvone not only demonstrates antioxidant, antimicrobial, anticancer, and anti-inflammatory properties [20,21,22,42], but that the S-carvone isomer reduces obesity induced by a high-fat diet and insulin resistance; it inhibits the inflammation that causes obesity by blocking the expression of genes such as Pparg, transcriptional factor sterol regulatory element-binding protein 1 c (Srebp1c), acetyl-CoA carboxylase 1 (Acc1), and fatty acid synthase (Fas), which are important in the process of lipogenesis. The gene discussed is FAS; the disease is obesity due to melanocortin 4 receptor deficiency.
