Agree. They're nothing more than paid advertisers. Especially the fitness industry and the money making/trading courses. They didn't make millions off their programmes they made millions off of you buying their programmes. Don't forget that you are their income. The reason they tell you "it works" and here's proof cos others have done it is just their way of wriggling out of response when you fail because " you didn't follow it correctly".
Leeches preying on people's insecurities.
