I have written both Paleo diet and Zone diet guides in the past.
My current philosophy is that we need to find a diet to suit our own physiological and health requirements. I am currently writing an updated nutrition guide book based on my current research. This is not a one size fits all, but rather a guide to important nutrition principles such as feeding our gut bacteria, managing inflammation appetite regulation.
