Does Diet work?

How Come Diets Do Not Work?
It is a failry well known fact that diets do not work, you may lose the weight but is it healthy weight loss? Was it body fat or healthy muscle that you lost? And how fast did it take to put it ALL back on again and then some?

So why is this?
-Diets are not balanced.
They recommend foods that stimulate the wrong hormonal reaction to burn fat and lose weight.

-Diets are not personalized.
They use a one-size-fits-all concept, which fails to take into account your own specific requirements.

-Diets are not easy.
They are far to restrictive and difficult to follow, and certainly are not something you can employ for a lifetime
