Yes! Hypnosis that is what it is Hypnotherapy for weight loss and it does work only if you want it to.
I perform Hypnosis and do therapy as well I see things in the performance level and in my sessions. Hypnosis on all levels to me is something that is mind over matter. The same happens to clients who gets hypnosis done for the wrong reasons then all the work is lost. So when you get hypnotized you got to have the desire and wants to do it to be effective.
The theory behind hypnosis for weight loss is this it is actually easy nothing difficult all it takes is for people to relax and to let go and follow the directions. It is said the smarter you are the faster you will go into trance. That's true but also the less you fight it the better you will be. For weight loss all you need is the want and desire to lose those pounds you have been holding on to for all those years.
My suggestion is to find a picture of yourself at the weight you desire and place it somewhere you can easily see in the morning and it will set your mind on the right track.
Diets are a bad thing, There are so many myths to diets but for us not knowing all the facts we follow the fad diets. Hypnosis is not a diet its a plan a desire to enhance our life. Weight loss is easy with some help and it starts with the mind.
Another suggestion Do not weigh yourself that is self sabotage by doing this you are looking to see if the changes are taking place now. It took you a long time to gain that weight it will take a while for you to lose it. Hypnosis will help you to overcome any doubts and hesitation when it comes to weight loss. Nothing is easy it takes committment to achieve what we want in life and weight loss is one of them.
