I've had a sweet tooth all my 53 years. I was diagnosed pre-diabetic six years ago. And for the last six years the pattern has been: 1) I incrementally improve my diet... 2) I return for another A1c test (hopeful that I've "moved the needle" a little bit).... and 3) I'm STILL about 6.2%. It has been very frustrating. Some background: at 53, BMI of 24, exercise regularly, and (after five years of improvement) eat a better diet than 95%.... I don't really fit the standard profile About two months ago by blood pressure started bouncing all over the map. 50 point swings each day, measured carefully at rest. Faced with the proposition of going on blood pressure medication AND hovering next to being diabetic, I decided to try Newcastle Diet. (I figured it couldn't hurt, and it might really help.) After four weeks at 800 kcal /day and a complete fast for 16 hours each day, I've lost 16 pounds (10% of my weight) and my blood pressure problem is gone. When I started my fasting blood glucose was 5.5 -6.0 every morning. Now its 4.7- 5.0, but there's no real trend downwards. I have two questions. 1) How can I tell when to stop the diet? should my fasting numbers get to a certain level? Is there a "glucose stress test" I can do at home? My understanding is the A1c tests the three month average... So that won't really help. BOTTOM LINE: how can I tell when I've cleaned my liver and pancreas of what I am sure was 40+ years of accumulated lipids?? 2) I've decided I want to maintain my current weight. (BMI of 21.5) Is is there a trick to leaving a reduced calorie diet without increasing weight? The obvious thing is to simply increase very slowly and let my body adjust. Does anyone have experience or tips how to do this... especially for someone in my somewhat unusual case? Thank you!
