You are making the assumption that blood glucose remains steady with the eggs and bacon for most of the day.
Have you tested that? For me, eggs and bacon would give a gentle sloping rise then fall (maybe 1mmol/l in all) which would last 2-3 hours. Then my bg would drift nicely downwards and then coast til my next meal. But I only know this through steady testing every half hour or so, all day.)
And - this is key - what are your bg levels
before you eat either breakfast? Do you test your fasting blood glucose, and your pre-breakfast blood glucose?
Have you heard of Dawn Phenomenon? AKA morning glucose dumps? Your raised bg after the protein breakfast could be more to do with Dawn Phenomenon than what you ate for brekkie.
As
@bluetit says, it is the rise from the food that is most important. So you need to measure before eating, and then 2 hrs later, consistently, to be able to compare different meals. And in order to compare them properly, you would need to have the same amount of exercise after each meal, otherwise you are introducing some pretty wild card variables (time, exercise AND carbs).
Sorry if I am making it sound complicated. It isn't. We just have to be consistent during the testing phase, then once we have learned our body's reactions to set meals, we can be much more free flow about it all.
