I have been on reduced carb, with balancing fats, for 5 years now. I'm now additionally gluten-free, but this isn't diabetes related. My stats go something like this:
T2 since October 2013. No medication.
HbA1c:
October 13: 73 or 8.8% (How did that happen?)
February 14: 37 or 5.5%
May 14: 34 or 5.3%
August 14: 32 or 5.1%
November 14: 33 or 5.1%
May 15: 31 or 5.0%
October 15: 33 or 5.1%
September 16: 31 or 5.0%
November 17: 33 or 5.1%
March 18: A "bonus", unexpected test due to other bloods - 30 or 4.9%. I joined the 4s club! I hadn't expected a reduction, having got used to toggling 33<>31<>33<>31 for the last 3 years, literally.
Work in progress, but GP has taken me off the Diabetes Register.
It seems to work for me. All medical markers improved from the point of diagnosis. I'm just about due an annual A1c test, but I did a home A1cNow test about 4 weeks ago, prior to some extended travel, and it came in at 4.8%. I usually find those to be +/-0.1% pf my lab results.
Could we help you with anything in particular?
Edited to add that this forum supports whatever works for any given individual, it's just that quite a few folks, particularly T2s, have found reducing carbs to be helpful to them.
