Review: This book was amazing. I found it when I was diagnosed with type 2 diabetes years ago. Dr. Bernstein has a somewhat radical idea that instead of letting blood sugar peak and then pull it back down with meds or insulin is dangerous long term. His idea of controlling and achieving normal blood sugar levels by controlling diet is very good. I have been able to control mine for a number of years, my A1C is 5.3, and excellent value. My doctor got this book after I explained the ideas contained and he agrees with the plan Dr. Bernstein promotes here.
