Conjugated linoleic acid (CLA) combined with treadmill exercise may decrease fat mass and increase lean muscle tissue, according to research published in the Journal of Nutrition.
Researchers began their study stating, “Nearly half of the U.S. adult population is overweight or obese, which may be related to increased energy intake combined with lack of physical activity. Obesity increases the risk of several chronic diseases including diabetes, coronary heart disease, hypertension and stroke.
“Conjugated linoleic acids (CLA) were shown to decrease fat and increase lean mass in several animal studies. However, the effects of CLA in combination with exercise on body composition have not been studied in an animal model. We examined the effect of a low concentration of either safflower oil as control (0.5%) or mixed isomers of CLA (0.4%) along with treadmill exercise on body composition in male mice fed a high-fat diet.”
Scientists found that CLA consumption lowered fat mass and a combination of CLA and exercise decreased fat mass even further. Lean mass did not increase with exercise alone but increased significantly due to the combination of CLA and exercise. Also, serum insulin, glucose, tumor necrosis factor and interleukin-6 were lower in CLA-fed mice.
“In summary,” researchers said, “the combination of dietary CLA and exercise decreased fat mass and increased lean mass in mice fed a high-fat diet.”
