I agree with the other 5-star reviews. So far, the book has helped me lose ten pounds. I plan to lose another ten and stay at my healthy weight level using the recommendations given in the "Plan" portion of the book—basically, cut out sugar, starches, carbs, and soda and eat a diet high in healthy fats and protein, veggies, and some fruit and dairy. Of course, get some exercise and proper sleep, and maybe a cute dog.
The book is well worth the read. If you get bogged down in too much detail, skip those parts. Every chapter has explanations that non-doctors can understand.
The book makes an excellent connection between improper advice on diet and how that is making us unhealthy AND that improper diet is connected to many of the diseases that most of us are affected by: cancer, diabetes, Altimers, fatty liver, heart disease, and others.
I suggest that the author write a shorter, easier-to-read version of the book suitable for non-doctors.
