CLA is primarily used to decrease body fat levels. Studies show that diets high in CLA, whether taken naturally or as a supplement, helped decrease overall caloric retention, assisting in the metabolism of body fat and preventing metabolic slow-downs on diets.

Studies also show that CLA can help prevent the body from holding onto unhealthy water weight, which is one of the most common contributors to overall weight. CLA helped improve the body's natural abilities to absorb vitamins and nutrients, such as A and D, which helps improve cellular function.
