As a person with type 1 diabetes I would like to add that, just as one has to learn what amounts of insulin to inject when one first starts using insulin with his/her given diet, one would need to learn what amounts of insulin are appropriate for the days one is on this diet.

And if you had to abort the fast a few times before you home in on your insulin needs during the fast, that is not a life or death situation.

I feel you are being too cautious. Please chime in if you feel I'm being cavalier. Thanks!

I too use a continuous glucose monitor.
