Does Tonalin CLA Work?
Tonalin CLA and Fat LossA few small studies have suggested that supplements such as Tonalin CLA may be effective for reducing body fat. These studies did not show that CLA caused weight loss, but it did cause a decrease in body fat and, presumably, an increase in muscle mass. There is some evidence that CLA may help suppress the appetite, as most types of fat tend to do, although it is not clear if this results in an overall reduction in calorie intake. More studies are necessary to confirm that CLA is both safe and effective for this purpose.
More importantly, one isomer of CLA may increase the risk of diabetes in people with abdominal obesity (fat around the midsection). Therefore, this product may not be the best choice for people with this body type. Because Tonalin CLA contains this particular isomer in combination with another one, it is not clear if the supplement also causes such problems.
