[Q]: This book was a wellspring of information for me as a newly diagnosed type 2 diabetic. Getting off the cycle of being told to eat complex carbs, seeing my blood glucose spike from doing just what I was told, and getting medications increased again and again, I read what Dr. Bernstein said with interest. After trying his recommendations I can say with no reservations that this book may have saved my life! I highly recommend it to anyone who has pre-diabetes or diabetes and hope that the general medical community opens their eyes. After only one day of this diet my blood glucose readings were close to normal, and continue to stay there, with less medication. My energy levels are high and I have felt better than I have in a long long time. Kudos to you Dr. Bernstein, for daring to say the truth! I recommend both his books and also Dr. Atkins Diabetes Revolution to anyone who wants to learn about diabetes and diet.
[A]: Positive


[Q]: Beware of the size of this book!If you are expecting to receive a regular size art book, you will be extremely disappointed. The book measures 7.5 x 9 inch and is thinner than my pinky finger.However, if you are just interested in the content, there is a lot to look at and to read.
[A]: Negative


[Q]: This novel is widely regarded as overrated. The plot is not that interesting, the writing style is torturous,the plot twists are predictable. It's a typical example of pre-20th century bad writing. Not to say that any book from that era is crap, but this book certainly is.
[A]:
Negative
