My hypoglycaemia feels more stable on low carb and I wouldn’t say everything else drastically declined at the same time. But yes maybe it could be causing some longer term damage which is becoming more and more apparent.
What sort of digestible carbs are you eating day to day? Do you have a rough idea of how many grams you are consuming? 60 tends to be the threshold for ketosis. In fruit terms that would be 3 apples which I know my gut would struggle with. For starch it would be less but I’m in the same boat in being unable to digest it very well.
I tend to get brain fog and tiredness when reintroducing carbs. Maybe I need to push through this. I tried white rice in small amounts for 2 weeks and felt horrible! Hoping the plan will helps with my constipation but 8 days in its not looking good!
