One of the latest products promoted to help you lose weight is conjugated linoleic acid, a derivative of an omega-6 fatty acid found in meat, chicken, diary products, corn or soybean oil, eggs, sunflower seeds and so forth.

The sellers cites nine studies in animals that show weight loss. The studies we found all came from the same respected research group at the University of Wisconsin. The sellers cite a human study from Norway, but we cannot find any evidence of this study in our medline review. The study quoted by the seller of the product shows a 20% reduction of body fat in 20 subjects in three months without any change in diet or exercise. We have to be suspicious of any claims for a product that is being sold to help people lose weight that has not been approved by the FDA and we cannot find human benefits in our search of the medical literature. We could find no good data on side effects.
