Yes folks, it is 90 days.
It is a diet that is out of balance according to the food pyramids and such. But, it is a temporary plan that is used to cleanse the system and reset the metabolism.
There are plenty of vegetables in this plan, but they are veggies that are more beneficial and carry a higher value. There is also a benefit of lifestyle change - Four regular meals to spread out the intake to match usage.
Like I said, I know others that have done this, and they are all visiting their doctors for regular preventative care. None have had anything negative come from it - All positive. That is the thing that always concerns me when I hear that somebody is trying something.
