Abstract

Conjugated linoleic acid (CLA) and conjugated nonadecadienoic acid (CNA) have been previously shown to effectively reduce body fat. However, it is not clear if these effects persist with extended feeding, including potential mechanisms of increased energy expenditure. Thus the current investigation was conducted to determine the influence of dietary conjugated fatty acids on non-exercise form of voluntary movement and lipid and glucose metabolisms for 4-12 week feeding of male mice. CLA and CNA significantly reduced body weight and fat mass by increasing energy expenditure, in part by increasing voluntary movement. CLA and CNA significantly reduced serum leptin and tumour necrosis factor-α, while modulating the mRNA levels of genes associated with lipid and glucose metabolisms. The current results of increased physical activity along with modulation of lipid and glucose metabolisms by conjugated fatty acids will help contribute to future applications of these toward controlling obesity.
