Hi Jo, I am very pleased that you happed to have a doctor who gave the correct advice about carbs - still so rare! Too bad he kept to that old crazy idea that you can (as jjraak put it) 'drive without a speedo'. A meter is essential to enable you with a low carb diet. Otherwise how can you tell which meals were wrong or just slightly too much etc. We are all slightly different in our tolerance of carbs, some can eat root veg, but I can't without spiking my BG. Don't expect too much of the DN - you have already beaten the odds with the GP! Hi NDP, Do you have a BG meter? 45 is not really high - was that before the Metformin? Diet as in Lifestyle (unless you are a lot overweight in which case a little more diet than lifestyle) is a bigger factor in reducing Blood Glucose levels than exercise. The standard 5 x 30min brisk walks per week is sufficient for most - no need to risk your health in a gym!
