It does, though I can't bring myself to believe it. I did some testing using a Freestyle Libre 2 last month, by which time I had lost around 17Kg since diagnosis. During the 14 days I intentionally ate a range of foods that I've been largely avoiding and took screenshots of my blood glucose responses to those foods. The plan is to repeat the experiment in June, by which time I hope to hit my target weight, and again early next year. The idea to to determine whether my insulin secretion improves as Roy Taylor documented in his research, by eating a series of repeatable high-carb meals and creating BG graphs I can compare over time. I want to know if I have gained any greater capacity to process carbs over time following weight loss as Taylor suggests is possible, and use the information to guide my eating patterns in future.
During the 14 days of testing I had numerous big BG spikes, as you'd expect, but the calculated HbA1c for the two weeks remained very low. HbA1c is a good blood test but it is a reflection of average BG over several weeks to months. Big BG spikes make hardly a dent on HbA1c so long as they only last a few hours of the day. For this reason I don't trust that a series of low HbA1c test results would give me carte blanche to eat whatever I like - I don't trust remission-level blood test results to protect my eyes in the hours after a pizza feast. Maybe BG spikes are irrelevant in the context of a generally low average BG level. Maybe not. I just can't bring myself to believe that a low HbA1c result means that any potential harm from eating masses of carbs in one sitting is now 'on pause' so long as my next HbA1c is also low, if that make sense.
