Hypnosis and Weight Loss

Is hypnosis effective for weight loss? I'm hoping to get some feedback from any people who have tried hypnosis for losing weight.

As one example of the various hypnosis products being sold today for weight loss, there is a guy out there named Alfonso De Rose who is selling a hypnosis CD and claims that this is a revolutionary new way to lose weight by eradicating overweight issues in the subconscious mind. De Rose calls himself a 'master of human behavior'. He says "obesity has its roots inside your mind. It's not what you eat but what you think."
