The usual timing is two hours after starting to eat.
If you have been doing a different timing then maybe do a double check to see if the result is very different and maybe select the one you feel is most useful.
I have been having a ding dong on Twitter with a number of people who all claim different reasons for other people having diabetes or have opinions on how to cure it - the last one was certain that we only needed to lose weight (by which he meant fat) and all would be well.
Sigh.
Not one was prepared to come and help on a diabetes forum so - I suspect it was rather a wasted effort on my part.
I have been isolating for a while, and sometimes the cupboards are a bit bare.
I have had a cauliflower and seafood 'curry' where the steamed from frozen ingredients were mixed with mayonnaise into which curry powder was stirred then the result was left in the warm for ten minutes for the temperatures to even out from scalding hot to fridge cold.
I found a packet of kippers in the bottom of the freezer and made a sort of bready slice to put them on - I would have had low carb Livlife bread from Waitrose normally.
There was the white fish with cauliflower sort of kegeree, so there are alternatives to eggs if you have eggs for breakfast.
I think that type two diabetes can be different things which have got lumped together, but easy weight gain is far more usual with type two than being slender. I too think that you need to keep your GP on their toes just in case you are not the ordinary type two after all.
