Yes, we should.
I'm only losing weight (and very slowly at that) by upping the miles. That can't go on indefinitely. I need to change my attitude to food.
And I have developed a position professionallu of no faith in the jedi mind-tricks NLP tosh, I'm afraid.
I have lost 20kg in four years, I suppose, hitting various plateaux on the way, but I can do with losing another 10kg I think.
The Jedi Mind Games are only one of the techniques of NLP, and you seem to suggest that underlies your lack of "faith"; that is similar to suggesting that you don't believe in speedreading techniques, so you won't pick up a book.
When I was on my NLP course alongside numerous work colleagues, I would say around 50% did not "get" the jedi mind tricks, I was probably a borderline. However, 100% "got" the NLP idea which is so blindingly simple and obvious: You can control other people's minds - and your own - with words. Bear in mind that in this context control is not to make someone like an automaton, but instead to influence them towards a position.
The other people's minds part is something everyone does to a greater or lesser extent; NLP sets out to put some (quasi?) science around it that you may or may not appreciate. It sure as hell works for some people - Derren Brown ?. Put a suggestion to a person in the right language and you are much more likely to achieve your goal.
The real eye opener of NLP, though, is how much it applies to what goes on inside your own head, and then your own physical capabilities. Again, it isn't magic, and it isn't even news: you have to think of yourself as a winner before you stand a chance. It (_and_ the Jedi Mind Tricks - that business with his hands) are what helped Johnny Wikinson achieve what he did, but it hasn't given him superhuman powers.
The question posed (and the reason I came out of the woodwork on this thread) was, can a person learn not to want to want to eat? That has nothing to do with dieting, everything to do with attitude changing and something that NLP could possibly deliver.
My weight loss history up to a couple of years ago was of yo-yo dieting, at the end I was 110Kg and been stuck there for a number of years, while still cycling upwards of 100 miles a week, and I realised that only a radical change of attitude would help me, but I couldn't find it. For me, the Paul McKenna book together with the NLP stuff I knew about did the trick. I went down and stayed at 85Kg for about 2 years, crept backup to 103 as a combination of dropping back from my 60 mile/day commute which allowed me anyamount of beer and being off my feet for a few months, and I'm on my way back down again with negligible pain or difficulty (93 at the mo).
What works for one person doesn't for another, but if you are looking for a way to reprogram your thinking, you would be unwise to dismiss NLP without giving it a fair shot.
