Pipp, I'm amazed that you don't occasional test any more - especially as you are radically changing your eating patterns.
I appreciate you consider your diabetes to have gone away, and you have restarted the diet to lose weight solely.
In your shoes I might feel absolutely zero testing + rising weight might be riding my luck a little too far.  I'd be testing, driven by fear, I think.
Have you considered testing, see if the diet further impact your blood scores?
		
		
	 
Thank you, AndBreathe, I don't really consider my diabetes to have gone away.  It is lurking somewhere ready to pounce just when I don't expect it. i am not dieting solely to lose weight, I am doing so to make sure I don't get elevated BG again.  I do have 3monthly HbA1c checks by GP nurse. So I am not really zero testing.
I have had a lot of quite scary health stuff going on since I first lost the weight so rapidly a few years ago.  This was due to my accident 20 odd years ago.  I have had two major operations requiring me to be in intensive care. A reason or possibly excuse for my lapse. I have recently been in and out of hospital, where they insisted on doing BG tests 4 times a day, and even in the days, which were frequent, when I wasn't eating BGs were averaging 4.2.
My GP nurse told me to stop doing tests myself when I finished my first stint of Newcastle dieting.  Whether this was an acknowledgement of my achievement or cost cutting I am not sure.  I have, only this morning retrieved my BG monitor from the bag to go to the tip, having already thought about the wisdom of doing such a radical eating regime and not testing.  Of course the test strips are out of date so I have sent for some more.  In the meantime, I got a diabetic mate to test for me.  Post prandial 2 hours, 4.8.
I am monitored by GP and local weight management service, who know what I am doing. I am awaiting latest HbA1c results, and will discuss with nurse, but you are right to flag up the wisdom of testing when changing diet.  I am grateful to you. It is important that others do not misunderstand what I am doing.That is what is so good about this forum.  We, have just as much, if not more,  knowledge as health professionals.
Many thanks
Pipp
