I know this is going to sound stupid but I wasn't aware this was a high carb diet, there's less bread in my diet than I have been advised to eat, I've been advised to have bread with every meal!!
The problem with the "healthy diet"/"eatwell plate" is that these diets are very high in glucose. So much so is that even a reduction by half or two thirds can still be too much for some people.
It's the "starchy foods" which are highest highest in glucose. Thus reducing these is likely to be more important for blood glucose control than anything to do with "sugar". Indeed you'd have to turn a cup of coffee into a thick syrup to get as much glucose in it as two slices of bread.
I've started to test my BG this week, not enough information yet to spot trends etc, although it does seem to be raised most of the time.
How often are you testing and what results are you getting.
Fed up already with the lack of information from my GP/DSN and I'm only 7 weeks into this.
Lack of information may be better than bad information though.
The other thing to be concerned about would be the Satins. (Diabetics already have one major metabolic disorder. Deliberatly inducing another isn't the most sensible of things.) Having, drug induced, hypocholesterolemia will do nothing to help with diabetes. If anything it's likely to make it worst. (With things like neuopathy being symptoms of both diabetes and hyopcholesterolemia...)
According to a BHF/WHO study the "healthy range" for cholesterol is 5.2-6.2 mmol/l with lowest CVD risk being at 5.4 mmol/l. It's also possible for HMG-CoA reductase inhibitors to shift LDL towards "pattern B", which increases CVD and stroke risk. (A high LDL-C in an insulin resistant person may may actually be due to their liver attempting to reduce harmful pattern B LDL particles.)
The only really useful tests for determining CVD risk are apoB count or LDL count and size profiling. (Even where LDL-C is actually measured it's of little use since the number of LDL particles is of far greater importance.) Since the common justification for dishing out Satins like "sweeties" is reduction of CVD risk it's utterly daft not to perform the relevent tests FIRST.
By comparison Metformin is a fairly safe drug. Unlikely to do any harm even in people it does no good.
N.B. LDL, HDL, (VLDL & IDL) are lipoproteins NOT "cholesterol" and anyone who insists of calling them that simply dosn't know what they are talking about.
