This is the finest diabetic book that I have ever read. The excellent ones all recommend a high-carbohydrate, low-fat, plant-based diet, but this one explains why we should follow this diet. I have been a whole-food, plant-based eater for around five years, but I ate too many nuts, nut butters, and seeds despite the fact that they are entire foods.
As soon as I read the explanation in this book, I saw why too much fat was harmful. My insulin consumption went from 30 units per day to 12 units per day, and it seems to be moving even lower, and my blood sugar management has improved to the point that it is almost predictable, while on a high-fat diet, my blood sugar was like a random walk.
I adore this book! BTW, except when I’m fasting, I’m never hungry. Intermittent fasting is not required, but it does help you lose weight and activate your cellular defenses. Eating according to the advice in this book will help mend your metabolic disease, and you will lose weight. Good luck!!!!
