(google Somogyi Effect).A fasting bg check is just that.......you don't eat anything.  The advice is to just drink water in-between, so if you are testing to see how your bg fluctuates between breakfast and tea you would eat breakfast as normal (make sure it's low in fat) and then begin to test your bg 4 hours after eating, you would skip lunch altogether (including your insulin) and continue to test every hour up until tea-time, by rights if your basal insulin is set at the right dose it shouldn't increase or drop by more than 1.7mmol/l, if it does then you need to increase or decrease your basal dose.  Best to do fasting bg checks on a day where your not going to be particularly stressed or more active than usual.As for protein, it converts to glucose in the absence of carbs by around 50%, I find I need nearly as much insulin for low-carb meals with protein than I do for a meal with carbs and a moderate amount of protein and fat.</blockquote>
