Hypnosis, for safe weight loss

I went to a hypnotist show, and I bought a CD to help me loose weight. Im a overweight teenager, and I desperately need to loose weight! Does anyone know if it really works? PLEASE HELP.

The guy who made the CD is named Mark Yuzuik. Thanks!

I just saw a comercial, telling you it could trigger your body to loose weight just by making you listening to a CD and then you just like loose 30 pounds? I personally dont believe it, but what do you think?

Is it all just BS?
