mental fog

[Drfarxan]

Is it the diet or the insulin resistance i don't know or it might have nothing to do with either. Any of you experienced the same?a mental fog after starting a keto diet or around being diagnosed with dm 1 or 2 or lada? Just trying to find out if it had anything to do with those 2

A year before being diagnosed i had the same issue,insomnia although not severe definitely played a part i know. But i want to know if you guys have the same experience since being diagnosed or starting lchf? or maybe you experience the opposite?


A month ago i let myself go with carbs and even eat cakes it was a holiday and what not. My sugar was below 100 most of the time and my hba1c is 5.7.I find it hard to have energy after going back to keto. Diabetics have a hard time going into ketosis or just adapting to a lchf, according to professionals this is normal it takes non diabetics 1 to 2 weeks. How long did it take after starting or going back to lchf diet for you to adapt?

There's being "in ketosis" and being "fat adapted" which are two different things and can happen quite a while apart, for some it can take a couple of months to become truly fat adapted and it will to an extent depend on how much stored glucose you have.
Once your glucose stores are depleted and you aren't adding any extra then your body will become used to running on fat and ketones. Until then you may feel weaker with less energy a bit like marathon runners "hitting the wall" (not that I have any personal experience of that!).
Your holiday binge has probably restocked your glucose stores so you'll likely have to burn through those before you are back to being fat adapted.

The brain fog is probably something similar as almost everyone I have ever encountered has reported a lifting of brain fog once taking up keto.

I've posted several times before about my brain fog which was caused by a (not to my choice!) high carb diet well before I was diagnosed with T2. As soon as I cut back down on the carbs after diagnosis it cleared.

Re ketosis vs fat adapted: I'd always eaten normal full fat food for 70+ years, so my body was already well used to dual fuel mode burning fats as well as carbs for fuel. But I'd agree that going from a long term high carb diet to a low carb one could result in a lack of (brain) fuel while a body (re)learned how to use fat as extra fuel to replace an often drastic reduction in carbs

However, having got to basic grips with our T2 fuel mechanics system, I don't really understand why my brain fog, except perhaps scoffing all those additional carbs meant I wasn't ever needing to use the fat I still ate and presumably it was just getting stored away for some possible future eventuality....
