I've always believed that out minds can do a lot more for s than we give them credit for. I've used positive thinking, affirmations and meditation to bring about positive changes in my life.

Another method of using the mind is hypnosis. Can hypnosis help you lose weight? According to the Weight Loss Information Blog, it might be worth a try:

Hypnosis facilitates the success of your weight loss plan by changing your mindset on the conscious level; not via the conscious route but by continually feeding positive thoughts into your subconscious mind, by changing your mindset inside out, by reprogramming the way your subconscious mind feels about food.

Mun's Fitness Blog agrees:

Hypnosis is one of the most natural ways to lose weight. Permanent weight loss occurs with a change in lifestyle, not through unnatural diets that are impossible to maintain. Hypnosis can help you make those changes.

If you don't want to trust your mind to someone else, self hypnosis is a great way to go. This Wiki How has the steps:

Many people are interested in hypnosis as an alternative therapy, but are turned away by the fact that a hypnotherapist may charge anywhere from 50 to 150 dollars per hour for a session. Some simple issues can easily be dealt with using this technique.
