I'm sure that you tried one of the diets that are available out there.
I did not write all of the diet there are because we will stay here a long time, because there are so many.
But the question is?.if there are so many diet programs how can it be that I can't make even one until the end of it? Why?

The answer is really simple, and maybe that you will be a little bit disappointed.
It's because you don't really want to make the change, you're not 100% positive that you want it, simple as that.
You probably saying that it is not true, or that it is, but not to you.
I have news flash? this is it, simple as that.
And I will tell you why you do not really want the change.

Most of your diets is based on by the way decisions, it's mean that you looking in the mirror and telling you self "I'm fat; I need to do a diet".
And this is how you relate to that.
What you need to do, is take it serious, you need to operate the situation, and ask your self why?
Why do you what to go on a diet?
In this question what you did is you ask yourself a question that in order to answer yourself on it you have to link pain to it.
What do I mean?
You make a list of the all thing that bother you, for example: "people laughing at me", I can't run", "I can't breathe after I climb the stairs" and so on and so on?.

After you do a list of all the painful things that bother you, you will have a reason to make diet, and every time you will want to quit, you look on the list and feel the pain, and that is want will drive you!
