Thanks for the replies.
I have a non fasting blood glucose level of around 5mmol and a ketone level of between 0.5 - 1.1 . No metabolic conditions that I know of. I do have raised blood pressure and an under active thyroid for which I am taking medication for both).
My reasons for wanting to eat this way are to lose body fat which is about 45% the last time I checked but also to be more healthy overall. I believe in this way of eating but the main driver for me is to lose the fat.
The nuts are because I like to have something to nibble on in the evening when watching tv and not because of hunger. I will cut them out and see if this makes a difference.
