I think the point here is that there isn't just a diet for Type 1. It's a whole lot more factors than that. Logically, it makes sense to reduce carbohydrate in order to reduce the need for insulin and therefore the variance attributable to that, but it's not the only thing that matters. I've spent plenty of time eating low carb, and not had any physiological resistance. But at the same time I've also exercised, usually involving a decent amount of resistance training. Much along the lines of what Bernstein recommends, as it happens. Why is this important? We all know that exercise is great at increasing insulin sensitivity as it seems to activate and maintain GLUT4 transporters in an active state. I personally find that, even with pre-bolusing, and we're talking 30-45 mins here, standard carbs will still cause me to go higher than I want to, which is not an issue I see with low carbs. The doses are right, but the way the insulin works just doesn't offset the effects of the food properly. I also find that if I need to lose weight, low carb works. Moderate carb just doesn't. But then we're all different. A lot of non-forum members have jumped on the low carb approach and had very good results from doing so. Quite a lot of forum members have too. While education can help with getting numbers in line, typically, the DAFNE outcome is measured in reduction in Hba1C, not achieving the recommended level, as even then, very few DAFNE graduates do. What's been interesting reading the Libre group on Facebook is the number of people realising that reducing their carb intake makes a big difference to the mountain range that they see on the device. Sure, they also learned about pre-bolusing and basal testing more efficiently, but that's been one of the biggest things to come out of the widespread Libre take up that I've seen. But rather than rambling on, I don't think there is a T1 Diet. If you look at any personal training approach to getting body transformation results, they don't simply say one size fits all. Any diet that you decide to use needs to work for you, so for some, 180g of carbs a day might be fine, but for others, it simply doesn't work. My advice would always be to try the various approaches until you find something that works for you. My best variance and Hba1Cs have been achieved using low carb, so that's a diet that works for me.
