When I switched to a ketogenic diet my need for NDT dropped significantly - I went from 2.25 tablets to 1.25. For the first 8 months or so I stuck to 20-25grams of carbohydrate daily. That's not a lot, and significantly limits variety in the diet. So I bought myself a ketone meter and started to experiment with higher levels of carbohdrates. I found I could eat about double the original amount as long as I kept away from sugar and high carb foods like rice and potato.
I didn't notice that I was becoming more fatigued, and my weight even crept up a little bit. Its taken over 3 months for me to realise that my T3 levels must have dropped! I increased my NDT the last 3 days and feel heaps better!
So, I want to understand the whole process of T4 to T3 conversion better. I've found references to the diet improving conversion in people on medication. But what is the role of blood glucose? and/or ketone levels?
