So many people know what they need to do, but cannot make the mental shift to make that change in lifestyle. Changes in eating habits, changes in training habits - or even getting started in training full stop. There is always an excuse, a convenient lie - and before long that excuse becomes the norm. This excuse then becomes, in their minds, the truth and it is very hard to get somebody to change when they "believe" in something that is the truth.
It comes down to the ability to be brutally honest with yourself.....do you have a problem and do you want to fix it. Write it down, the truth hurts sometimes, but if you can acknowledge a problem, you have taken a massive step to overcoming it.
Establish the problem, develop a plan to overcome it, and get going. It sounds simple when put like that, we understand it isn't, but will help you at every stage to get you there.
