Body Type Diet

I need some help!  I am reading your book  Perfect Health and found out through the quiz on your web site and the descriptions in your book I am Pitta Vata type.  The problem I am finding is I am not sure which diet to follow to get back into balance.  When I started my Vata was very out of balance.  I am following the Vata balancing diet. When I took the test on line  today after being on the diet and following a consistent daily routine my answers changed me from Vata Pitta to Pitta Vata.   So I am not sure how to proceed?  I feel really great but want to continue to do the right thing.
