I got my various diagnosis at the end of last january
Carbs are basically sugars (when processed after eating), so I only needed to minimise added sugars and concentrate on carbs. I initially cut carbs to 100 grams a day, and later increased those to 130, for the last 4 months they've been 150 grams a day and my bloods came back ok, so 150ish is obviously ok for me now. The future, well I guess I can play chicken with the carbs - increase a bit more, and see how the next blood test is.
I'm just eating a reduced amount of protein (within the guidelines) rather than substituting, a bit annoying but meh, health matters. Fats is easy of course, limit saturated, job done.
I haven't been well since I had Covid in march 2021 but am actually a whole lot better than I was! Ever since then I've had an ectopic heartbeat, low energy & low stamina, so what I do on any given day depends on how I feel, and if I feel I need a rest day.
The dietary changes were easy to put in place as I've had no real appetite in the past 4 years. But I did lose a load of weight (I needed to). I noticed my resting heart rate was dropping and told my doc it seemed due to the rapid weight loss. He agreed, and I altered my diet again to get more food / calories.I'm still working on stabilising my weight - the dietician does not want me to lose more. It's been a challenging year.
Strange but true Covid side affect for me ...
After I got it I was completely unable to drink alcohol
As soon as it hit my stomach I got raging hiccups!
Occasional testing found that i was starting to tolerate it a little, and that effect seems to have gone now
