Dr Davis's new book UnDoctored has a basic strategy that he claims works for most chronic lifestyle diseases, and he added a few other specifics for a some conditions. For diabetics, of the basics, he claims "cultivation of bowel flora" most important as it helps restore the body's response to insulin. Surprisingly for the extras, he has no supplements at all. Instead, follow a no-change rule for BG, achieve ketosis, and like Dr Fung, engage in Intermittent Fasting.
