CLA is a safe and effective weight loss aid containing no harmful stimulants. Studies show that it may increase lean muscle and reduce the amount of fat stored in body. CLA is an essential fatty acid that helps reduce body fat and increase lean muscle tissue. Studies demonstrate that CLA inhibits lipoprotein lipase, an enzyme which breaks down fat globules so they can be absorbed and stored as fat cells in the body. By inhibiting this enzyme, CLA helps reduce the amount of fat deposited and stored throughout your body. CLA also enhances your body's ability to metabolize existing fat deposits by breaking down stored fat, which returns to the blood stream where it is used as energy by muscle cells. CLA increases lean muscle tissue while maximizing your body's fat-burning potential. Muscle tissue is denser and more compact than body fat, which results in your body being firmer, looking thinner, and feeling more energetic. CLA is best known for helping to reduce body fat and increase lean muscle tissue. CLA is scientifically-proven to help you obtain your diet goal two ways: CLA increases lean muscle mass, which naturally slims your body. Then, the added muscle burns more fat. This way, you lose weight in the right places and drop clothes sizes. Some scientists have linked the steady rise in obesity in the U.S. over the past 30 years to the reduction of CLA in our diets. There are two reasons: Americans have substantially reduced their consumption of beef and dairy products. Additionally, changes in beef and dairy cattle feed (from pasture grasses to forage) have reduced their production of CLA by 65%.
