A questions here...
Your highs when you haven't done exercise for a couple of days! Are you adjusting your insulin dose to compensate for lack of exercise!
I've never tried low carb pasta, but I do find that making my own pasta it doesn't impact on my blood glucose in the same manner has shop brought pasta...
I would agree with the 'Trend' of T1's doing Bernstein, it something I've seen over the years, it comes into fashion then disappears again, similar to any VLC diet mainly due to only a few are able to maintain their motivation over a long period of time...
When you looking into VLC diets, it's wise to pay very particular attention to your insulin dose, and your insulin profiles, Bernstein actually uses 3 types of insulin, a background, a soluble quick acting i.e humulin S and a quick acting insulin such as humalog.. The latter being mainly used for corrections..
As the older soluble insulin, has a slower profile to reach it's peak, so can be easier to match it's slower profile to the adsorption of high fat/protein meal..
Another thing you've got to consider and be wry off, is when you running your BG in a tight range near the lower end of the 4's this can diminish you hypo awareness... As the more time you levels duck under the 4mmol/l and run just under this mark, it desensitise the body's hypo warning symptoms, which then means when you do pick up hypo's you have a very brief window to get yourself out of the hypo, before a medical emergency is created...
Another consideration, is do you have a driving licence! Because running your levels at the bottom end of 4mmol/l, which could mean you are ducking under 4mmol/l for period of times, this will revoke your driving licence... If you have a driving accident, and it's found that you've started your journey at the low end of 4mmol/l and your BG has dropped below this then you could land yourself up in court, driving without due care and attention and/or driving under the influence...
But whether you have to go to a vlc diet, may be not.. May be that you just need to look at the portion sizes you eat, and cut these back slightly to improve good control... T1's I know who have been long term diabetic, and I'm talking about 40plus years, all eat a normal but moderate carb diet, and haven't suffered long term complications...
I eat a normal diet, but it's not that high in carbs as such but I do have a small appetite so in my case this helps...
