I bought the book and CD called 'I can make you thin' by Paul McKenna. It's useful in retraining your habits, but as everyone else has said you have to want
to do it. It doesn't work by magic either. You won't suddenly find yourself losing weight without changing your lifestyle.
What it does is help you adjust to new lifestyle choices. You want
to eat slower, you want
to exercise more, you want
to eat only until you are satisfied. And after a while you find yourself doing these things without thinking about it. I've been slack the last week and haven't listened to it, so I'm finding a few of my old habits creeping back. While I was listening to it every day I found I was making healthy decisions without thinking.
I highly recommend hypnosis as a way to support conscious lifestyle changes. I wouldn't recommend it as a substitute
for those changes, though. You still need to eat better, eat less and exercise more unfortunately!
