I have no idea, Gezzathorpe! I think we need Yorksman to answer these questions as he knows so much. ;-)

I cannot work out whether variation or predictability in the diet would be better. Would the body respond better to a degree of unpredictability of carb intake or does the pancreas respond better when it knows what to expect? At the moment I'm taking the 'predictable' approach by having a small amount of carbs in the evening with (so far) no big spikes. However, after a few days it seemed to create slightly higher preprandial readings, and then the preprandial readings seemed to fall slightly, and just when I thought I had a predictable pattern the preprandial figures went up just a bit.
So…what works for you? Do you have your carbs evenly divided and predictable to avoid spiking?

I did read from yet another incredibly reliable source! that first-phase insulin is based upon previous recent meals.
Who was that source Gezza? I'm interested

janeecee said:Vivienem, I'm a bit curious as to how you know how many carbs I eat. It's not as if I post what I eat on here. But anyways…I don't eat a lot of carbs. I was eating 80-90g per day on average and half of that from veg and my one portion of fruit per day, which is some sort of berry. Yesterday I had salmon with non-starchy veg and I was 7.2 at 1 hour and 6.0 at 2 hours. Strictly speaking, that's hardly non-diabetic numbers, and to be honest I've had better numbers eating small quantities of pasta at 1 and 2 hours, so I don't get it at all.
As for fat—perhaps I should make this a sticky —I cannot stand fatty foods, I can't digest fats easily. Even tinned mackerel is a bit heavy in the stomach for me. Being lactose intolerant I need to avoid cheese, cream, butter and all that stuff. The smell of bacon makes me want to puke, honest. For some folk it makes them hungry, but it has the opposite effect on me. Eating fatty foods makes me bilious.
I don't know what the answer is, and I don't know what stage I am at re beta cells etc, and whether there is any hope for restoring it, or whatever else. Nothing seems to be helping, as far as I can tell. When I've cut back on carbs my numbers have actually gone up.
I've never had a sugar habit and didn't eat much in the way of cakes and pastries etc, and with no weight to lose, all the advice dished out to prediabetics is of no use to me. I rarely touch alcohol, I think the last time I had a glass of wine was February, and before that it was Christmas. So, I have nothing to "give up". Even on Friday I ate only 850 kcal trying to keep the numbers down, and that isn't sustainable.
I don't get these GPs saying 9s and 10s at 2 hours is 'normal' but I will persevere with them.

Janeecee, I didn't mean to upset you and I hope I haven't. I was going by the one meal that you posted on here earlier, which contained both chickpeas and brown rice. I know you said they were both small portions and I believe you, but even a tablespoonful of each, eaten together, would spike me. But as I say, I'm carb intolerant.
I do know that some people can't tolerate fats, and definitely that Atkins doesn't suit everyone. Lactose intolerance must be a real pain!
As I said before, I didn't mean to cause any offence. Apologies if I did.
If you've told all the above to your various GPs and got nowhere, even with all your readings and food recorded in a diary to show them, in your place I would be pushing to see a consultant.
Sadly, diabetes isn't well covered in GP's basic training, and they tend to cover Type 1 rather than Type 2. In addition, the words "Diabetes Specialist GP" don't necessarily mean they know that much more about diabetes - just that they have responsibility for all the diabetics in the practice, and are the first point of communication. They do get extra training, I believe, but it's basic NHS training which is a tad out of date!
Good luck

It seems that spiking does quite a lot of damage. Yes, everybody spikes, but it's the length of time that matters. By 2 hours after eating you should be back within the appropriate range. I work on less than 7.8, 2 hours after eating, which is supposed to be more beneficial than the "below 8.5" that is quoted for Type 2s.
Even short bursts of very high blood glucose does some damage to the small blood vessels. Mince pies are my worst - 11.2, 2 hours after eating one :shock: . So I don't eat them any more.
The problem with relying on an HbA1c to check your BG control is that the highs and lows cancel each other out over time - smooth the curve, so to speak - so you don't know exactly what's happening - and nor does the doctor!
It's interesting to check your blood reactions against a non-diabetic occasionally, if you don't mind changing the lancets (and if you can get a non-diabetic to co-operate!). Last time my brother came we had fish & chips (a little treat for me ). I had a handful of chips, cod in batter and mushy peas, and was 6.2, 2 hours after - very pleased with that.
He had about 5 times as many chips, with the same fish and mushy peas. 5.2, 2 hours after. That's what our BGs would be doing if our insulin response, whether production or resistance, was okay.
I eat chocolate sometimes, too. But no more than a couple of squares of 85% cocoa solids, which doesn't spike me.
In short, I try not to eat anything that will leave me over 7.8 at the 2 hour mark, except very, very occasionally.
Hope this helps!

Below is an idealised glucose response curve:
The speed of the insulin response, the amount of insulin produced and the insulin sensitivity all play a part. Hence non diabetics get a lower peak. The area under the three different curves reflects the the glucose levels in the blood plasma. This in turn allows more glucose to bind with the haemoglobin, the hba1c measure. Over the period of a day, the total area under a graph means there is considerably more glucose in the blood, despite it going up and down:
