The best-selling HHY book I wrote was never launched in a digital version. Physical copies sold out however, we keep back some stock which is available on the HHY site. Here is a PDF version you can access as part of being a member of the Butterworth Health Optimisation Portal. I am also loading all the recipes to the Butterworth Health Website for you and will do some sessions on the different topics I go into in the book. The first section of the book clearly outlines what you need to do for your health to flourish and a lot of the Health Optimisation concepts are in the front of the book, so it is really worth spending a few hours and reading through it.
