I found a short, informative article on the Mayo Clinic website, titled "How effective is hypnosis for weight loss?". The article states that hypnosis could be one of the tools you use to lose weight. It mentions that numerous studies have evaluated the effect of hypnosis and weight loss and have found fairly positive results. For, when you are under hypnosis, you are in a relaxed state. This state makes you much more focused and open to suggestions such as making healthy changes towards losing weight. The article does stress that hypnosis is not magic - that you need to combine the hypnosis with exercise and a healthy diet. It also emphasizes the need to find therapists with good training and reputation.
I found this article interesting because, more often than not, when you hear the medical institutions talk about remedies, you hear about pills. So I was enthused to see the Mayo Clinic actually give a nod towards weight losswith hypnosis. We need all the help we can get when we are on a diet - a stream of "you-can-do-it" to counter the stream of junk food advertising combined with your mental "can't do" stream of thought. A focus, relaxed mind can program your unconscious mind to be your friend, helping you pinpoint your personal weight loss sabotagers - and providing a path towards improved behaviors instead.
