CLA (conjugated linoleic acid) is a naturally occurring fatty acid found in meat, cheese and dairy products. Supplementing with CLA has been shown in studies to help reduce body fat by inhibiting the activity of the enzyme lipoprotein lipase (LPL). This enzyme transfers fats from the bloodstream to the fat cells. As a result of the decreased enzyme activity the transport of fat into fat cells is blocked. At the same time CLA also stimulates the breakdown of stored body fat (lipolysis).
