Input: Consider Input: 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.

Output: Positive

Output: Positive


Input: Consider Input: I found this book to be very well authored. It shows what you need to know and gives a very detailed method of teaching you the same technique. Though I think the overuse of wrist locks to be inneffective the overall method is great and proven in competition by wally jay and his students (see the history provided in the book)


Output: Positive
