Ah yes,
@tiredgirl91 - it will be very interesting, and important for you of course! To find out if you are a LADA/MODY case - having an autoimmune disease rather than a metabolic one at least.
The issue of you possibly having anemia, and that affecting your blood glucose readings has been posed. (And you are just within the very low prediabetes range, for many countries at least.)
The matter of nutrition, and keeping you well fed is much more straight forward! You need a decent amount of protein and healthy dietary fat to survive and thrive. With those two macronutrients, and water, those macros are not 'options on the menu' in the way choosing a way of eating is, and what level of carbs to eat is. If you are skinny, and getting skinnier because fats make you feel sick, and proteins spike you so you are choosing not to eat them? - you have a really big immediate health issue at stake. Malnutrition can kill you, or at least go a long way to causing the organ damage that puts your life in danger. I hope you don't mind me being direct about this.
You need to eat protein, regardless of the spiking involved demonstrated on your blood glucose meter. And some fat. Just to repeat - Eating protein and fats and getting enough water are not options for us to live and thrive.
You may already be being seen by a nutritionist? What are your loved ones, and your doctor saying about your being nourished properly by food? If you don't mind me asking... I know it's pretty personal. But the deep dive into food and nutrition is pretty par for the course in this Forum, due to the dietary nature of metabolic disease, and the fact that management of the autoimmune diabetes also requires knowledge of food and macros and so on. This means that in depth discussions of diet and exercise sometimes, are a big part of what we share.
