The authors provide an easy-to-implement four-week sugar-detox program that definitely -- I can attest firsthand -- gets results, with respect to everything from energy levels to weight loss to skin health. What's more, they explain (in layman's terms) the basic science that underlies the processes of curtailing sugars from one's diet, on both a temporary and permanent basis. By understand exactly how, from a biochemical perspective, eliminating/reducing sugar from my diet results in holistic health benefits, I found myself especially motivated to sustain these practices beyond the 31-day cleanse.
The midsection of the book gets mired in a long digression about skincare habits, which seems somewhat tangential (if not entirely unrelated) to the main subject. There's also a lengthy tangent about incorporating a routine exercise regimen into one's lifestyle. It's not unhelpful but, speaking as someone who's worked with a personal trainer, it's hard to visualize a particular exercise by reading a paragraph-long, step-by-step description of it; it's more effective to see it actually demonstrated by a trainer at the gym or even on a YouTube video. The chapters on skincare and exercise, however superfluous, are well-meaning and not altogether unhelpful, but the book's real value is the sugar-detox program itself, along with its detailed, week-by-week menu of approved foods and beverages.
Bottom line: As an accessible how-to manual, The Sugar Detox outlines the steps and supplies the encouragement required to dramatically reduce one's dependence on processed sugars. I'm not someone who ever considered himself a "sugar addict" -- I don't for the most part eat cookies or candy bars -- but I was genuinely surprised how much processed sugar I was consuming through other (non-sweet) foods. This book has made me more conscious of my dietary habits, and for that reason, I recommend it to anyone considering this simple-yet-effective lifestyle change.
