Hi Joxy
Have a look at Viv's Modified Atkins Diet , which is a Sticky Thread on the Low-carb Diet section of the forum. Not only will you lose weight on this, but it will lower your blood glucose, blood pressure and cholesterol levels.
The diet as it stands is very low carbohydrate - 25g daily. As your blood glucose has been running high for a while I wouldn't go that low immediately - maybe start on about 100g carb daily and lower that over a number of weeks. As Candiloo says, a Carb Counter book is essential for adding in lower-carb vegetables and fruit until you get your desired amount of carbs. Not too much fruit - berries, apricots and plums are not too bad. If you want bread, look for Bergen, which is full of seeds and lower carb/lower GI, and have 1 or at most 2 slices daily.
Don't be afraid of fat - natural unprocessed fat, that is. Stay away from anything processed or artificial, eg shop-bought cakes. But you won't be eating those, will you? :wink:
Do you have a blood glucose meter? You really do need to monitor your blood glucose levels very carefully as you reduce your carbs, because you will probably have to reduce your medication too, otherwise you may end up going hypo. I suggest, before you start, that you go to discuss this with your GP. Don't tell him/her that you are going very low carb; some (like mine) approve, but many others don't. Say you are going to try contolling your carb intake to help you lose weight and get control of your BGs, and ask him what you should do about your medication. And ask for test strips on prescription, if you don't already get them. And you will need to test first thing (as soon as you wake up), before each meal, 2 hours after eating, and at bed-time. Once you get control and learn what you can and can't eat, you'll test less often.
As for A&E - yes, many people, particularly Type 1s, go to A&E with levels over 15. If you feel very ill with it, get yourself down there. You can't be too careful.
Hope this helps. Ask any questions you like - there's no such thing as a silly question, on this site.
