Does Hoodia Work?
Many people may wonder about the effectiveness of hoodia. While individual testimonials suggest that it does indeed help with weight loss, no studies have actually been published on the product's safety and effectiveness. Even if these testimonials are genuine, they do not prove that the supplement works. Until adequate studies are performed and published, it cannot be assumed that this product is effective for weight loss.
Hoodia is an herbal supplement marketed to help people lose weight. However, just because it is marketed for weight loss does not mean that hoodia actually works. In fact, no published research studies have shown hoodia to be effective for weight loss, and no studies have been performed and published to show that hoodia is safe. Therefore, while individual people may report success with hoodia products, this does not scientifically demonstrate that it is indeed effective.
Phytopharma (a well-respected manufacturer of supplements) claims to have conducted a study that shows hoodia to be effective. This study was "double blind," which means that hoodia was compared to a placebo (a "sugar pill" with no active ingredient), and neither the subjects of the study nor the researchers knew who received hoodia and who received the placebo. This way, it could be seen how effective hoodia really is (since some people will lose weight, even if they do not take hoodia). In this study, the people taking hoodia decreased their calorie intake and their body fat. Notice that this study does not mention weight loss, per se.
It is very important to understand that the Phytopharma hoodia study was never published and is, therefore, of little value. Unless a study is published, it cannot be reviewed by other independent sources.
