I don't know for sure if I'm in Ketosis but it's highly likely.Research has shown that ME/CFS patients are short of several amino acids. To stay in ketosis one must be fairly low in protein also.
Are you sure you're in ketosis?
And are you taking supplements to make up for the nutrients not in this radical diet, like folate, B5, biotin, alpha lipoic acid, vitamin E, molybdenum, iodine to name just a few?
.
Regarding protein: this is a misconception. The important factor is the amount of carbs per day.
It's not a fixed value but 20g is a level which keeps almost everyone in ketosis.

To illustrate my level of nutrients I've added two screenshots of a report of the app I use for tracking ( Cronometer).
And yes, I take supplements... more than I like to admit ;-)
Multivitamin, Magnesium, Vit D3, Vit B12, Curcumin, Thiamin, Nac, Vit C, etc...

Unfortunately since living with CFS my intellectual capacities have degraded massively.
Therefore usually - if something seems worth a shot - I try it and see if it has any benefits.
With Keto I've improved quite a lot - especially in the beginning - but even after a year it's a positive factor.
As always it's not a cure but helpful.
With NAC + LDN it has helped the most.
