Well I'm a bit late arriving to this thread sorry guys, I only just noticed my name appearing several times.
To the OP I would say I agree with Bluetit1802 - you're BG's are shooting up high because you are eating more carbs. I also agree with her that a low carb diet is for life. I would say if you are only prediabetic and feel you are fine with a little less than 100g of carbs then stick with that level and see what happens. Keep checking your BG's. I am sorry that the squabbling broke out on your thread. Please don't be put off by this. You may be anewcomer but you are still a valid member of the forum - welcome
To everyone else:-
A fuller version of the quote I used a precis of in another thread is this:-
(thank you Indy51 for showing me this in the first place)
Dr Eades:
"Following a low-carb diet makes one a little glucose intolerant, which is the reason that the instructions for a glucose tolerance test always include the admonition to eat plenty of carbs in the week before the test. Why? Because all the macronutrients–glucose, fat and protein–are broken down by enzymes during the metabolic process. And all the enzymes necessary for the metabolism of the various macronutrients are made on demand but not immediately.
If you are on a high carbohydrate diet, then you will have plenty of enzymes on hand to deal with the carbohydrates you consume. If you switch to a low-carbohydrate diet, it takes a while to manufacture the enzymes in the quantities needed to deal with the extra fat and protein that your metabolic system hadn't been exposed to. This deficiency of protein/fat metabolizing enzymes is the reason people starting a low-carb diet become so easily fatigued–they've got plenty of enzymes on hand to break down carbs, they just don't have the carbs to metabolize. Once they produce the enzymes necessary to deal with the load of protein and fat, which takes a few days, they become low-carb adapted and no longer feel fatigued.
Once people become low-carb adapted then the same thing happens if they go face down in the donuts. They don't have the enzymes on board to deal with the sudden influx of glucose, and, as a consequence, their blood sugar spikes higher than it would on a person eating the same amount of carbohydrate who is already carb adapted."
So the answer would seem to be adopt the diet you feel suits you (and low carb generally suits diabetics, particularly type 2's) and stick with it, then there should be no problems.
I originally gave a précis of this to a forum member because he was convinced that you could 'train your pancreas' to produce more insulin by eating doughnuts and pot noodle. I was trying to explain that it is in fact the enzyme levels which take a while to catch up when there is a change of diet. I was not saying that low carbing is bad because the enzyme levels take a few days to adjust. I was saying eating junk food is bad.
Now to those of you who don't like low-carbing, that is fine you are free to follow whatever diet you like. I have no problem with that. However please do not try to put others off because they may like to try it too, surely that is also their right? I am aware that sometimes people have twisted my words to try to make me look bad in the eyes of my fellow low-carbers. I am and always will be a strong believer that low carb is the way to go (for anyone, diabetic or otherwise).
I have posted on this thread because my name was mentioned (I wasn't tagged though, so I wasn't given a fair chance to defend myself). I do not intend to comment further as I no longer wish to be involved in petty arguments with someone who may simply be posting to make others look bad and to cause unnecessary rifts between us. We should all be fighting against diabetes, not each other.
To the OP: hopefully you can claim your thread back now

I wish you all the best..
