A client told me he began thinking to himself that he was losing weight. He felt more energetic and was more aware of his eating choices. After a couple of weeks he was amused to find that several of his friends asked him if he had lost weight.
When he got on the scale, he discovered he was the same weight. No more. No less. And so he went back to his old way of thinking and returned to his old eating habits. Now you and I know that if he had continued, he probably would have lost weight. You don’t have to be a doctor to realize that if you eat better and move more, you will eventually lose weight. But what this also illustrates is his ability to effect his own perception and the perception of others by what he was saying to himself.
