I have been doing a LCHF diet for 1 year and 2 months now, Im type 1 since 35+ years!
My Hba1c have been around 7.9 - 8.0 for years and I have not been able to improve it much.
I started LCHF, in 3 months my HbA1c dropped from 7.9 to 6.5, my doctors response was, your LDL is HIGH, you must take statins! I resisted since my triglycerides and HDL was good or very good. The next check my LDL was back in acceptable levels, still 'high' but enough for my doc not to freak out. My total colesterol was still on the high side, but if you considered all values they where not bad.
As Alaska states, there is no proof that 'high' LDL is bad for you if you are not in the risk zone, and getting your HbA1c down will reduce your risk.
The improvements that I have seen:
* Better HbA1c!
* Less highs
* Less lows, AND when I do have lows I have much less reaction, before I tried to follow the 15 rule, but often ate much more than 15g carb, because I felt so bad and I 'needed' the carbs, this got me high .... now I treat my hypos with 4g sugar or even less and I feel much better (keton power!!)
* I feel more focused, I had not realized how tired you get by yoyo-ing between 15 and 3 mmol/l blood sugar all the time, since I had been doing that for 30+ years I was used to it. Now I feel bad when I reach 8, before 8 was an ok value.
* I lost almost 10kg, no big thing but good for sure.
* I don't feel it, but I'm pretty sure that I have stopped all complications that was catching up with me, I really think/hope that my next eye check will say that the three very small spots that I had have gone away.
Low carb is good for you, keep the good work up!!
