Interesting discussion, I have very recently lowered my carb intake to between 60 and 100g per day, not a big issue from a preparation perspective as we usually prep all our own food and eat a pretty healthy diet that doesn’t make it hard to ditch some of the carbs.
Why did I do it? It makes my life a huge amount more pleasant, or has so far. On paper, my HbA1C was pretty good (40-44) and all my blood markers were excellent. I was a sugar surfer and kept a close eye on things (I weighed most of the food I ate), I documented, tested, experimented, documented and so on, I tested different doses of insulin on a stable BG, tested the response of carbs at different times and starting points. One of the key points for me was that with higher carbs and higher insulin doses, there were just too many sources of error and too many unpredictable reactions, although I could catch and prevent most extremes, it was still very frustrating at times. I also have inflammatory bowel disease which was quite unpleasant and funnily I couldn’t eat much fat without symptoms, overall IBS also complicated everything. Steered quite a bit by Michael Mosleys clever guts diet, I have played around with various diet changes, with one of the key positive changes for me being low carb, funnily I can now eat fat again and I don’t have constant stomach pain which is a bonus.
Where am I now? Still in the early stages of this, but as long as my insulin doses are < 2 units my life is much nicer. I don’t have quick swings and my BG is usually around 5.5 mmol, I’m a lot more comfortable running it lower, even when I exercise it doesn’t plummet like it used to on occasion. Interestingly as the weeks pass, I’m also needing a lot less carbs during exercise and not having issues post exercise either. I exercise most days, running, mountain biking (usually 60-120 minutes and a fair bit of ascent), weights etc. I will see how it goes and keep an eye on my blood markers. My bodies response to insulin and carbs has been quite variable in the past, so it is still early days.
Re the last point on blood markers, there are now quite a few intelligent, rigorous medics and researchers supporting lower carbohydrate diets from a cardiovascular health perspective, follow Dr Aseem Malhotra on twitter if you want to see lots of vigorous disagreement about this topic with both the for and against groups. There are a number of expert groups formed now in the UK supporting lower carbohydrate (“lower” being a key point?). There have been various articles in the last 18 months in the British Journal of Sports Medicine and similar on this topic and there should be a Cochrane review on its way in the very near future.
I am currently leafing through Dr Bernsteins book, and although he makes some interesting points generally, I couldn’t be described as a fan of his overall attitude and approach.
A final thought, I don’t think I’ve ever enjoyed food so much when we talk about unlimited, I just want to live the best life I can and be healthy, happy and wise (or least listen to wise people )
