This is a site that claims to expose the "truth" behind powerful diet pills and health aids. Many have the same ingredients and not all of them are listed. Besides, most people would not know what in the world those ingredients are, do, or mean! If you go to the warning website (just follow that link), you will find information on ingredients, ratings for popular pills and systems, and much more.
However, I urge you to do your own research and speak with a professional if you are serious about losing weight.
