Conjugated linoleic acid (CLA) is a naturally occurring fatty acid that affects the way our body stores and uses energy, causing a significant increase in lean muscle mass and a decrease in body fat. This also contributes to a more efficient metabolism, since muscles burn more calories than fat. CLA also inhibits enzymes that help break down fats, slowing the amount of fat deposited and stored in the body.
CLA occurs naturally in meats and dairy products. However, changes in eating habits and food production methods mean that we are getting 80% less CLA in our diets than 20 years ago. Many people have reduced their meat and dairy intake, and most beef cattle are now raised on grain-based feed, not grass rich in linoleic acid.
