After reading The 8-week Blood Sugar Diet, I've lost 13 pounds in two weeks and my waist has gone from 49" to 44" ( the measurement used by the author). The book is written by Dr Michael Mosley, with a foreword by Prof Roy Taylor (he of the Newcastle Diet). My Bg has also shown a significant improvement. From (fasting) 10.9 to 5.8.
The plan is basically a low-carb Meditterranean Diet, eating 800 calories a day for the eight weeks, with advice on what to do after the eight weeks.
I'm so happy I saw this book and even happier I decided to start on ihe plan straight away, rather than waiting for 1st January. My DN is very happy with my results, and I'm now seeing her monthly so she can monitor both my progress and BP in case my BP mess need to be reduced.
